| 57 | /** | ||
| 58 | * An interpreter for printf-style format strings. This class provides support | ||
| 59 | * for layout justification and alignment, common formats for numeric, string, | ||
| 60 | * and date/time data, and locale-specific output. Common Java types such as | ||
| 61 | * {@code byte}, {@link java.math.BigDecimal BigDecimal}, and {@link Calendar} | ||
| 62 | * are supported. Limited formatting customization for arbitrary user types is | ||
| 63 | * provided through the {@link Formattable} interface. | ||
| 64 | * | ||
| 65 | * <p> Formatters are not necessarily safe for multithreaded access. Thread | ||
| 66 | * safety is optional and is the responsibility of users of methods in this | ||
| 67 | * class. | ||
| 68 | * | ||
| 69 | * <p> Formatted printing for the Java language is heavily inspired by C's | ||
| 70 | * {@code printf}. Although the format strings are similar to C, some | ||
| 71 | * customizations have been made to accommodate the Java language and exploit | ||
| 72 | * some of its features. Also, Java formatting is more strict than C's; for | ||
| 73 | * example, if a conversion is incompatible with a flag, an exception will be | ||
| 74 | * thrown. In C inapplicable flags are silently ignored. The format strings | ||
| 75 | * are thus intended to be recognizable to C programmers but not necessarily | ||
| 76 | * completely compatible with those in C. | ||
| 77 | * | ||
| 78 | * <p> Examples of expected usage: | ||
| 79 | * | ||
| 80 | * <blockquote><pre> | ||
| 81 | * StringBuilder sb = new StringBuilder(); | ||
| 82 | * // Send all output to the Appendable object sb | ||
| 83 | * Formatter formatter = new Formatter(sb, Locale.US); | ||
| 84 | * | ||
| 85 | * // Explicit argument indices may be used to re-order output. | ||
| 86 | * formatter.format("%4$2s %3$2s %2$2s %1$2s", "a", "b", "c", "d") | ||
| 87 | * // -> " d c b a" | ||
| 88 | * | ||
| 89 | * // Optional locale as the first argument can be used to get | ||
| 90 | * // locale-specific formatting of numbers. The precision and width can be | ||
| 91 | * // given to round and align the value. | ||
| 92 | * formatter.format(Locale.FRANCE, "e = %+10.4f", Math.E); | ||
| 93 | * // -> "e = +2,7183" | ||
| 94 | * | ||
| 95 | * // The '(' numeric flag may be used to format negative numbers with | ||
| 96 | * // parentheses rather than a minus sign. Group separators are | ||
| 97 | * // automatically inserted. | ||
| 98 | * formatter.format("Amount gained or lost since last statement: $ %(,.2f", | ||
| 99 | * balanceDelta); | ||
| 100 | * // -> "Amount gained or lost since last statement: $ (6,217.58)" | ||
| 101 | * </pre></blockquote> | ||
| 102 | * | ||
| 103 | * <p> Convenience methods for common formatting requests exist as illustrated | ||
| 104 | * by the following invocations: | ||
| 105 | * | ||
| 106 | * <blockquote><pre> | ||
| 107 | * // Writes a formatted string to System.out. | ||
| 108 | * System.out.format("Local time: %tT", Calendar.getInstance()); | ||
| 109 | * // -> "Local time: 13:34:18" | ||
| 110 | * | ||
| 111 | * // Writes formatted output to System.err. | ||
| 112 | * System.err.printf("Unable to open file '%1$s': %2$s", | ||
| 113 | * fileName, exception.getMessage()); | ||
| 114 | * // -> "Unable to open file 'food': No such file or directory" | ||
| 115 | * </pre></blockquote> | ||
| 116 | * | ||
| 117 | * <p> Like C's {@code sprintf(3)}, Strings may be formatted using the static | ||
| 118 | * method {@link String#format(String,Object...) String.format}: | ||
| 119 | * | ||
| 120 | * <blockquote><pre> | ||
| 121 | * // Format a string containing a date. | ||
| 122 | * import java.util.Calendar; | ||
| 123 | * import java.util.GregorianCalendar; | ||
| 124 | * import static java.util.Calendar.*; | ||
| 125 | * | ||
| 126 | * Calendar c = new GregorianCalendar(1995, MAY, 23); | ||
| 127 | * String s = String.format("Duke's Birthday: %1$tm %1$te,%1$tY", c); | ||
| 128 | * // -> s == "Duke's Birthday: May 23, 1995" | ||
| 129 | * </pre></blockquote> | ||
| 130 | * | ||
| 131 | * <h3><a name="org">Organization</a></h3> | ||
| 132 | * | ||
| 133 | * <p> This specification is divided into two sections. The first section, <a | ||
| 134 | * href="#summary">Summary</a>, covers the basic formatting concepts. This | ||
| 135 | * section is intended for users who want to get started quickly and are | ||
| 136 | * familiar with formatted printing in other programming languages. The second | ||
| 137 | * section, <a href="#detail">Details</a>, covers the specific implementation | ||
| 138 | * details. It is intended for users who want more precise specification of | ||
| 139 | * formatting behavior. | ||
| 140 | * | ||
| 141 | * <h3><a name="summary">Summary</a></h3> | ||
| 142 | * | ||
| 143 | * <p> This section is intended to provide a brief overview of formatting | ||
| 144 | * concepts. For precise behavioral details, refer to the <a | ||
| 145 | * href="#detail">Details</a> section. | ||
| 146 | * | ||
| 147 | * <h4><a name="syntax">Format String Syntax</a></h4> | ||
| 148 | * | ||
| 149 | * <p> Every method which produces formatted output requires a <i>format | ||
| 150 | * string</i> and an <i>argument list</i>. The format string is a {@link | ||
| 151 | * String} which may contain fixed text and one or more embedded <i>format | ||
| 152 | * specifiers</i>. Consider the following example: | ||
| 153 | * | ||
| 154 | * <blockquote><pre> | ||
| 155 | * Calendar c = ...; | ||
| 156 | * String s = String.format("Duke's Birthday: %1$tm %1$te,%1$tY", c); | ||
| 157 | * </pre></blockquote> | ||
| 158 | * | ||
| 159 | * This format string is the first argument to the {@code format} method. It | ||
| 160 | * contains three format specifiers "{@code %1$tm}", "{@code %1$te}", and | ||
| 161 | * "{@code %1$tY}" which indicate how the arguments should be processed and | ||
| 162 | * where they should be inserted in the text. The remaining portions of the | ||
| 163 | * format string are fixed text including {@code "Dukes Birthday: "} and any | ||
| 164 | * other spaces or punctuation. | ||
| 165 | * | ||
| 166 | * The argument list consists of all arguments passed to the method after the | ||
| 167 | * format string. In the above example, the argument list is of size one and | ||
| 168 | * consists of the {@link java.util.Calendar Calendar} object {@code c}. | ||
| 169 | * | ||
| 170 | * <ul> | ||
| 171 | * | ||
| 172 | * <li> The format specifiers for general, character, and numeric types have | ||
| 173 | * the following syntax: | ||
| 174 | * | ||
| 175 | * <blockquote><pre> | ||
| 176 | * %[argument_index$][flags][width][.precision]conversion | ||
| 177 | * </pre></blockquote> | ||
| 178 | * | ||
| 179 | * <p> The optional <i>argument_index</i> is a decimal integer indicating the | ||
| 180 | * position of the argument in the argument list. The first argument is | ||
| 181 | * referenced by "{@code 1$}", the second by "{@code 2$}", etc. | ||
| 182 | * | ||
| 183 | * <p> The optional <i>flags</i> is a set of characters that modify the output | ||
| 184 | * format. The set of valid flags depends on the conversion. | ||
| 185 | * | ||
| 186 | * <p> The optional <i>width</i> is a non-negative decimal integer indicating | ||
| 187 | * the minimum number of characters to be written to the output. | ||
| 188 | * | ||
| 189 | * <p> The optional <i>precision</i> is a non-negative decimal integer usually | ||
| 190 | * used to restrict the number of characters. The specific behavior depends on | ||
| 191 | * the conversion. | ||
| 192 | * | ||
| 193 | * <p> The required <i>conversion</i> is a character indicating how the | ||
| 194 | * argument should be formatted. The set of valid conversions for a given | ||
| 195 | * argument depends on the argument's data type. | ||
| 196 | * | ||
| 197 | * <li> The format specifiers for types which are used to represents dates and | ||
| 198 | * times have the following syntax: | ||
| 199 | * | ||
| 200 | * <blockquote><pre> | ||
| 201 | * %[argument_index$][flags][width]conversion | ||
| 202 | * </pre></blockquote> | ||
| 203 | * | ||
| 204 | * <p> The optional <i>argument_index</i>, <i>flags</i> and <i>width</i> are | ||
| 205 | * defined as above. | ||
| 206 | * | ||
| 207 | * <p> The required <i>conversion</i> is a two character sequence. The first | ||
| 208 | * character is {@code 't'} or {@code 'T'}. The second character indicates | ||
| 209 | * the format to be used. These characters are similar to but not completely | ||
| 210 | * identical to those defined by GNU {@code date} and POSIX | ||
| 211 | * {@code strftime(3c)}. | ||
| 212 | * | ||
| 213 | * <li> The format specifiers which do not correspond to arguments have the | ||
| 214 | * following syntax: | ||
| 215 | * | ||
| 216 | * <blockquote><pre> | ||
| 217 | * %[flags][width]conversion | ||
| 218 | * </pre></blockquote> | ||
| 219 | * | ||
| 220 | * <p> The optional <i>flags</i> and <i>width</i> is defined as above. | ||
| 221 | * | ||
| 222 | * <p> The required <i>conversion</i> is a character indicating content to be | ||
| 223 | * inserted in the output. | ||
| 224 | * | ||
| 225 | * </ul> | ||
| 226 | * | ||
| 227 | * <h4> Conversions </h4> | ||
| 228 | * | ||
| 229 | * <p> Conversions are divided into the following categories: | ||
| 230 | * | ||
| 231 | * <ol> | ||
| 232 | * | ||
| 233 | * <li> <b>General</b> - may be applied to any argument | ||
| 234 | * type | ||
| 235 | * | ||
| 236 | * <li> <b>Character</b> - may be applied to basic types which represent | ||
| 237 | * Unicode characters: {@code char}, {@link Character}, {@code byte}, {@link | ||
| 238 | * Byte}, {@code short}, and {@link Short}. This conversion may also be | ||
| 239 | * applied to the types {@code int} and {@link Integer} when {@link | ||
| 240 | * Character#isValidCodePoint} returns {@code true} | ||
| 241 | * | ||
| 242 | * <li> <b>Numeric</b> | ||
| 243 | * | ||
| 244 | * <ol> | ||
| 245 | * | ||
| 246 | * <li> <b>Integral</b> - may be applied to Java integral types: {@code byte}, | ||
| 247 | * {@link Byte}, {@code short}, {@link Short}, {@code int} and {@link | ||
| 248 | * Integer}, {@code long}, {@link Long}, and {@link java.math.BigInteger | ||
| 249 | * BigInteger} | ||
| 250 | * | ||
| 251 | * <li><b>Floating Point</b> - may be applied to Java floating-point types: | ||
| 252 | * {@code float}, {@link Float}, {@code double}, {@link Double}, and {@link | ||
| 253 | * java.math.BigDecimal BigDecimal} | ||
| 254 | * | ||
| 255 | * </ol> | ||
| 256 | * | ||
| 257 | * <li> <b>Date/Time</b> - may be applied to Java types which are capable of | ||
| 258 | * encoding a date or time: {@code long}, {@link Long}, {@link Calendar}, and | ||
| 259 | * {@link Date}. | ||
| 260 | * | ||
| 261 | * <li> <b>Percent</b> - produces a literal {@code '%'} | ||
| 262 | * (<tt>'\u0025'</tt>) | ||
| 263 | * | ||
| 264 | * <li> <b>Line Separator</b> - produces the platform-specific line separator | ||
| 265 | * | ||
| 266 | * </ol> | ||
| 267 | * | ||
| 268 | * <p> The following table summarizes the supported conversions. Conversions | ||
| 269 | * denoted by an upper-case character (i.e. {@code 'B'}, {@code 'H'}, | ||
| 270 | * {@code 'S'}, {@code 'C'}, {@code 'X'}, {@code 'E'}, {@code 'G'}, | ||
| 271 | * {@code 'A'}, and {@code 'T'}) are the same as those for the corresponding | ||
| 272 | * lower-case conversion characters except that the result is converted to | ||
| 273 | * upper case according to the rules of the prevailing {@link java.util.Locale | ||
| 274 | * Locale}. The result is equivalent to the following invocation of {@link | ||
| 275 | * String#toUpperCase()} | ||
| 276 | * | ||

| 608 | * | ||
| 609 | * <h4> Width </h4> | ||
| 610 | * | ||
| 611 | * <p> The width is the minimum number of characters to be written to the | ||
| 612 | * output. For the line separator conversion, width is not applicable; if it | ||
| 613 | * is provided, an exception will be thrown. | ||
| 614 | * | ||
| 615 | * <h4> Precision </h4> | ||
| 616 | * | ||
| 617 | * <p> For general argument types, the precision is the maximum number of | ||
| 618 | * characters to be written to the output. | ||
| 619 | * | ||
| 620 | * <p> For the floating-point conversions {@code 'e'}, {@code 'E'}, and | ||
| 621 | * {@code 'f'} the precision is the number of digits after the decimal | ||
| 622 | * separator. If the conversion is {@code 'g'} or {@code 'G'}, then the | ||
| 623 | * precision is the total number of digits in the resulting magnitude after | ||
| 624 | * rounding. If the conversion is {@code 'a'} or {@code 'A'}, then the | ||
| 625 | * precision must not be specified. | ||
| 626 | * | ||
| 627 | * <p> For character, integral, and date/time argument types and the percent | ||
| 628 | * and line separator conversions, the precision is not applicable; if a | ||
| 629 | * precision is provided, an exception will be thrown. | ||
| 630 | * | ||
| 631 | * <h4> Argument Index </h4> | ||
| 632 | * | ||
| 633 | * <p> The argument index is a decimal integer indicating the position of the | ||
| 634 | * argument in the argument list. The first argument is referenced by | ||
| 635 | * "{@code 1$}", the second by "{@code 2$}", etc. | ||
| 636 | * | ||
| 637 | * <p> Another way to reference arguments by position is to use the | ||
| 638 | * {@code '<'} (<tt>'\u003c'</tt>) flag, which causes the argument for | ||
| 639 | * the previous format specifier to be re-used. For example, the following two | ||
| 640 | * statements would produce identical strings: | ||
| 641 | * | ||
| 642 | * <blockquote><pre> | ||
| 643 | * Calendar c = ...; | ||
| 644 | * String s1 = String.format("Duke's Birthday: %1$tm %1$te,%1$tY", c); | ||
| 645 | * | ||
| 646 | * String s2 = String.format("Duke's Birthday: %1$tm %<te,%<tY", c); | ||
| 647 | * </pre></blockquote> | ||

| 650 | * <h3><a name="detail">Details</a></h3> | ||
| 651 | * | ||
| 652 | * <p> This section is intended to provide behavioral details for formatting, | ||
| 653 | * including conditions and exceptions, supported data types, localization, and | ||
| 654 | * interactions between flags, conversions, and data types. For an overview of | ||
| 655 | * formatting concepts, refer to the <a href="#summary">Summary</a> | ||
| 656 | * | ||
| 657 | * <p> Any characters not explicitly defined as conversions, date/time | ||
| 658 | * conversion suffixes, or flags are illegal and are reserved for | ||
| 659 | * future extensions. Use of such a character in a format string will | ||
| 660 | * cause an {@link UnknownFormatConversionException} or {@link | ||
| 661 | * UnknownFormatFlagsException} to be thrown. | ||
| 662 | * | ||
| 663 | * <p> If the format specifier contains a width or precision with an invalid | ||
| 664 | * value or which is otherwise unsupported, then a {@link | ||
| 665 | * IllegalFormatWidthException} or {@link IllegalFormatPrecisionException} | ||
| 666 | * respectively will be thrown. | ||
| 667 | * | ||
| 668 | * <p> If a format specifier contains a conversion character that is not | ||
| 669 | * applicable to the corresponding argument, then an {@link | ||
| 670 | * IllegalFormatConversionException} will be thrown. | ||
| 671 | * | ||
| 672 | * <p> All specified exceptions may be thrown by any of the {@code format} | ||
| 673 | * methods of {@code Formatter} as well as by any {@code format} convenience | ||
| 674 | * methods such as {@link String#format(String,Object...) String.format} and | ||
| 675 | * {@link java.io.PrintStream#printf(String,Object...) PrintStream.printf}. | ||
| 676 | * | ||
| 677 | * <p> Conversions denoted by an upper-case character (i.e. {@code 'B'}, | ||
| 678 | * {@code 'H'}, {@code 'S'}, {@code 'C'}, {@code 'X'}, {@code 'E'}, | ||
| 679 | * {@code 'G'}, {@code 'A'}, and {@code 'T'}) are the same as those for the | ||
| 680 | * corresponding lower-case conversion characters except that the result is | ||
| 681 | * converted to upper case according to the rules of the prevailing {@link | ||
| 682 | * java.util.Locale Locale}. The result is equivalent to the following | ||

| 1769 | * <p> Format specifiers can reference arguments in three ways: | ||
| 1770 | * | ||
| 1771 | * <ul> | ||
| 1772 | * | ||
| 1773 | * <li> <i>Explicit indexing</i> is used when the format specifier contains an | ||
| 1774 | * argument index. The argument index is a decimal integer indicating the | ||
| 1775 | * position of the argument in the argument list. The first argument is | ||
| 1776 | * referenced by "{@code 1$}", the second by "{@code 2$}", etc. An argument | ||
| 1777 | * may be referenced more than once. | ||
| 1778 | * | ||
| 1779 | * <p> For example: | ||
| 1780 | * | ||
| 1781 | * <blockquote><pre> | ||
| 1782 | * formatter.format("%4$s %3$s %2$s %1$s %4$s %3$s %2$s %1$s", | ||
| 1783 | * "a", "b", "c", "d") | ||
| 1784 | * // -> "d c b a d c b a" | ||
| 1785 | * </pre></blockquote> | ||
| 1786 | * | ||
| 1787 | * <li> <i>Relative indexing</i> is used when the format specifier contains a | ||
| 1788 | * {@code '<'} (<tt>'\u003c'</tt>) flag which causes the argument for | ||
| 1789 | * the previous format specifier to be re-used. If there is no previous | ||
| 1790 | * argument, then a {@link MissingFormatArgumentException} is thrown. | ||
| 1791 | * | ||
| 1792 | * <blockquote><pre> | ||
| 1793 | * formatter.format("%s %s %<s %<s", "a", "b", "c", "d") | ||
| 1794 | * // -> "a b b b" | ||
| 1795 | * // "c" and "d" are ignored because they are not referenced | ||
| 1796 | * </pre></blockquote> | ||
| 1797 | * | ||
| 1798 | * <li> <i>Ordinary indexing</i> is used when the format specifier contains | ||
| 1799 | * neither an argument index nor a {@code '<'} flag. Each format specifier | ||
| 1800 | * which uses ordinary indexing is assigned a sequential implicit index into | ||
| 1801 | * argument list which is independent of the indices used by explicit or | ||
| 1802 | * relative indexing. | ||
| 1803 | * | ||
| 1804 | * <blockquote><pre> | ||
| 1805 | * formatter.format("%s %s %s %s", "a", "b", "c", "d") | ||
| 1806 | * // -> "a b c d" | ||
| 1807 | * </pre></blockquote> | ||
| 1808 | * | ||
| 1809 | * </ul> | ||
| 1810 | * | ||
| 1811 | * <p> It is possible to have a format string which uses all forms of indexing, | ||
| 1812 | * for example: | ||
| 1813 | * | ||
| 1814 | * <blockquote><pre> | ||
| 1815 | * formatter.format("%2$s %s %<s %s", "a", "b", "c", "d") | ||
| 1816 | * // -> "b a a b" | ||
| 1817 | * // "c" and "d" are ignored because they are not referenced | ||
| 1818 | * </pre></blockquote> | ||
| 1819 | * | ||
| 1820 | * <p> The maximum number of arguments is limited by the maximum dimension of a | ||
| 1821 | * Java array as defined by | ||
| 1822 | * <cite>The Java™ Virtual Machine Specification</cite>. | ||
| 1823 | * If the argument index is does not correspond to an | ||
| 1824 | * available argument, then a {@link MissingFormatArgumentException} is thrown. | ||
| 1825 | * | ||
| 1826 | * <p> If there are more arguments than format specifiers, the extra arguments | ||
| 1827 | * are ignored. | ||
| 1828 | * | ||
| 1829 | * <p> Unless otherwise specified, passing a {@code null} argument to any | ||
| 1830 | * method or constructor in this class will cause a {@link | ||
| 1831 | * NullPointerException} to be thrown. | ||
