Primitive types + * must be passed using wrapper types. The formatting + * is controlled by a control string. + *<p> + * A control string is a Java string that contains a + * control specification. The control specification + * starts at the first percent sign (%) in the string, + * provided that this percent sign + *<ol> + *<li>is not escaped protected by a matching % or is + * not an escape % character, + *<li>is not at the end of the format string, and + *<li>precedes a sequence of characters that parses as + * a valid control specification. + *</ol> + *</p><p> + * A control specification usually takes the form: + *<pre> % ['-+ #0]* [0..9]* { . [0..9]* }+ + * { [hlL] }+ [idfgGoxXeEcs] + *</pre> + * There are variants of this basic form that are + * discussed below.</p> + *<p> + * The format is composed of zero or more directives + * defined as follows: + *<ul> + *<li>ordinary characters, which are simply copied to + * the output stream; + *<li>escape sequences, which represent non-graphic + * characters; and + *<li>conversion specifications, each of which + * results in the fetching of zero or more arguments. + *</ul></p> + *<p> + * The results are undefined if there are insufficient + * arguments for the format. Usually an unchecked + * exception will be thrown. If the format is + * exhausted while arguments remain, the excess + * arguments are evaluated but are otherwise ignored. + * In format strings containing the % form of + * conversion specifications, each argument in the + * argument list is used exactly once.</p> + * <p> + * Conversions can be applied to the <code>n</code>th + * argument after the format in the argument list, + * rather than to the next unused argument. In this + * case, the conversion characer % is replaced by the + * sequence %<code>n</code>$, where <code>n</code> is + * a decimal integer giving the position of the + * argument in the argument list.</p> + * <p> + * In format strings containing the %<code>n</code>$ + * form of conversion specifications, each argument + * in the argument list is used exactly once.</p> + * + *<h4>Escape Sequences</h4> + *<p> + * The following table lists escape sequences and + * associated actions on display devices capable of + * the action. + *<table> + *<tr><th align=left>Sequence</th> + * <th align=left>Name</th> + * <th align=left>Description</th></tr> + *<tr><td>\\</td><td>backlash</td><td>None. + *</td></tr> + *<tr><td>\a</td><td>alert</td><td>Attempts to alert + * the user through audible or visible + * notification. + *</td></tr> + *<tr><td>\b</td><td>backspace</td><td>Moves the + * printing position to one column before + * the current position, unless the + * current position is the start of a line. + *</td></tr> + *<tr><td>\f</td><td>form-feed</td><td>Moves the + * printing position to the initial + * printing position of the next logical + * page. + *</td></tr> + *<tr><td>\n</td><td>newline</td><td>Moves the + * printing position to the start of the + * next line. + *</td></tr> + *<tr><td>\r</td><td>carriage-return</td><td>Moves + * the printing position to the start of + * the current line. + *</td></tr> + *<tr><td>\t</td><td>tab</td><td>Moves the printing + * position to the next implementation- + * defined horizontal tab position. + *</td></tr> + *<tr><td>\v</td><td>vertical-tab</td><td>Moves the + * printing position to the start of the + * next implementation-defined vertical + * tab position. + *</td></tr> + *</table></p> + *<h4>Conversion Specifications</h4> + *<p> + * Each conversion specification is introduced by + * the percent sign character (%). After the character + * %, the following appear in sequence:</p> + *<p> + * Zero or more flags (in any order), which modify the + * meaning of the conversion specification.</p> + *<p> + * An optional minimum field width. If the converted + * value has fewer characters than the field width, it + * will be padded with spaces by default on the left; + * t will be padded on the right, if the left- + * adjustment flag (-), described below, is given to + * the field width. The field width takes the form + * of a decimal integer. If the conversion character + * is s, the field width is the the minimum number of + * characters to be printed.</p> + *<p> + * An optional precision that gives the minumum number + * of digits to appear for the d, i, o, x or X + * conversions (the field is padded with leading + * zeros); the number of digits to appear after the + * radix character for the e, E, and f conversions, + * the maximum number of significant digits for the g + * and G conversions; or the maximum number of + * characters to be written from a string is s and S + * conversions. The precision takes the form of an + * optional decimal digit string, where a null digit + * string is treated as 0. If a precision appears + * with a c conversion character the precision is + * ignored. + * </p> + *<p> + * An optional h specifies that a following d, i, o, + * x, or X conversion character applies to a type + * short argument (the argument will be promoted + * according to the integral promotions and its value + * converted to type short before printing).</p> + *<p> + * An optional l (ell) specifies that a following + * d, i, o, x, or X conversion character applies to a + * type long argument.</p> + *<p> + * A field width or precision may be indicated by an + * asterisk (*) instead of a digit string. In this + * case, an integer argument supplised the field width + * precision. The argument that is actually converted + * is not fetched until the conversion letter is seen, + * so the the arguments specifying field width or + * precision must appear before the argument (if any) + * to be converted. If the precision argument is + * negative, it will be changed to zero. A negative + * field width argument is taken as a - flag, followed + * by a positive field width.</p> + * <p> + * In format strings containing the %<code>n</code>$ + * form of a conversion specification, a field width + * or precision may be indicated by the sequence + * *<code>m</code>$, where m is a decimal integer + * giving the position in the argument list (after the + * format argument) of an integer argument containing + * the field width or precision.</p> + * <p> + * The format can contain either numbered argument + * specifications (that is, %<code>n</code>$ and + * *<code>m</code>$), or unnumbered argument + * specifications (that is % and *), but normally not + * both. The only exception to this is that %% can + * be mixed with the %<code>n</code>$ form. The + * results of mixing numbered and unnumbered argument + * specifications in a format string are undefined.</p> + * + *<h4>Flag Characters</h4> + *<p> + * The flags and their meanings are:</p> + *<dl> + * <dt>'<dd> integer portion of the result of a + * decimal conversion (%i, %d, %f, %g, or %G) will + * be formatted with thousands' grouping + * characters. For other conversions the flag + * is ignored. The non-monetary grouping + * character is used. + * <dt>-<dd> result of the conversion is left-justified + * within the field. (It will be right-justified + * if this flag is not specified).</td></tr> + * <dt>+<dd> result of a signed conversion always + * begins with a sign (+ or -). (It will begin + * with a sign only when a negative value is + * converted if this flag is not specified.) + * <dt><space><dd> If the first character of a + * signed conversion is not a sign, a space + * character will be placed before the result. + * This means that if the space character and + + * flags both appear, the space flag will be + * ignored. + * <dt>#<dd> value is to be converted to an alternative + * form. For c, d, i, and s conversions, the flag + * has no effect. For o conversion, it increases + * the precision to force the first digit of the + * result to be a zero. For x or X conversion, a + * non-zero result has 0x or 0X prefixed to it, + * respectively. For e, E, f, g, and G + * conversions, the result always contains a radix + * character, even if no digits follow the radix + * character (normally, a decimal point appears in + * the result of these conversions only if a digit + * follows it). For g and G conversions, trailing + * zeros will not be removed from the result as + * they normally are. + * <dt>0<dd> d, i, o, x, X, e, E, f, g, and G + * conversions, leading zeros (following any + * indication of sign or base) are used to pad to + * the field width; no space padding is + * performed. If the 0 and - flags both appear, + * the 0 flag is ignored. For d, i, o, x, and X + * conversions, if a precision is specified, the + * 0 flag will be ignored. For c conversions, + * the flag is ignored. + *</dl> + * + *<h4>Conversion Characters</h4> + *<p> + * Each conversion character results in fetching zero + * or more arguments. The results are undefined if + * there are insufficient arguments for the format. + * Usually, an unchecked exception will be thrown. + * If the format is exhausted while arguments remain, + * the excess arguments are ignored.</p> + * + *<p> + * The conversion characters and their meanings are: + *</p> + *<dl> + * <dt>d,i<dd>The int argument is converted to a + * signed decimal in the style [-]dddd. The + * precision specifies the minimum number of + * digits to appear; if the value being + * converted can be represented in fewer + * digits, it will be expanded with leading + * zeros. The default precision is 1. The + * result of converting 0 with an explicit + * precision of 0 is no characters. + * <dt>o<dd> The int argument is converted to unsigned + * octal format in the style ddddd. The + * precision specifies the minimum number of + * digits to appear; if the value being + * converted can be represented in fewer + * digits, it will be expanded with leading + * zeros. The default precision is 1. The + * result of converting 0 with an explicit + * precision of 0 is no characters. + * <dt>x<dd> The int argument is converted to unsigned + * hexadecimal format in the style dddd; the + * letters abcdef are used. The precision + * specifies the minimum numberof digits to + * appear; if the value being converted can be + * represented in fewer digits, it will be + * expanded with leading zeros. The default + * precision is 1. The result of converting 0 + * with an explicit precision of 0 is no + * characters. + * <dt>X<dd> Behaves the same as the x conversion + * character except that letters ABCDEF are + * used instead of abcdef. + * <dt>f<dd> The floating point number argument is + * written in decimal notation in the style + * [-]ddd.ddd, where the number of digits after + * the radix character (shown here as a decimal + * point) is equal to the precision + * specification. A Locale is used to determine + * the radix character to use in this format. + * If the precision is omitted from the + * argument, six digits are written after the + * radix character; if the precision is + * explicitly 0 and the # flag is not specified, + * no radix character appears. If a radix + * character appears, at least 1 digit appears + * before it. The value is rounded to the + * appropriate number of digits. + * <dt>e,E<dd>The floating point number argument is + * written in the style [-]d.ddde{+-}dd + * (the symbols {+-} indicate either a plus or + * minus sign), where there is one digit before + * the radix character (shown here as a decimal + * point) and the number of digits after it is + * equal to the precision. A Locale is used to + * determine the radix character to use in this + * format. When the precision is missing, six + * digits are written after the radix character; + * if the precision is 0 and the # flag is not + * specified, no radix character appears. The + * E conversion will produce a number with E + * instead of e introducing the exponent. The + * exponent always contains at least two digits. + * However, if the value to be written requires + * an exponent greater than two digits, + * additional exponent digits are written as + * necessary. The value is rounded to the + * appropriate number of digits. + * <dt>g,G<dd>The floating point number argument is + * written in style f or e (or in sytle E in the + * case of a G conversion character), with the + * precision specifying the number of + * significant digits. If the precision is + * zero, it is taken as one. The style used + * depends on the value converted: style e + * (or E) will be used only if the exponent + * resulting from the conversion is less than + * -4 or greater than or equal to the precision. + * Trailing zeros are removed from the result. + * A radix character appears only if it is + * followed by a digit. + * <dt>c,C<dd>The integer argument is converted to a + * char and the result is written. + * + * <dt>s,S<dd>The argument is taken to be a string and + * bytes from the string are written until the + * end of the string or the number of bytes + * indicated by the precision specification of + * the argument is reached. If the precision + * is omitted from the argument, it is taken to + * be infinite, so all characters up to the end + * of the string are written. + * <dt>%<dd>Write a % character; no argument is + * converted. + *</dl> + *<p> + * If a conversion specification does not match one of + * the above forms, an IllegalArgumentException is + * thrown and the instance of PrintfFormat is not + * created.</p> + *<p> + * If a floating point value is the internal + * representation for infinity, the output is + * [+]Infinity, where Infinity is either Infinity or + * Inf, depending on the desired output string length. + * Printing of the sign follows the rules described + * above.</p> + *<p> + * If a floating point value is the internal + * representation for "not-a-number," the output is + * [+]NaN. Printing of the sign follows the rules + * described above.</p> + *<p> + * In no case does a non-existent or small field width + * cause truncation of a field; if the result of a + * conversion is wider than the field width, the field + * is simply expanded to contain the conversion result. + *</p> + *<p> + * The behavior is like printf. One exception is that + * the minimum number of exponent digits is 3 instead + * of 2 for e and E formats when the optional L is used + * before the e, E, g, or G conversion character. The + * optional L does not imply conversion to a long long + * double. </p> + * <p> + * The biggest divergence from the C printf + * specification is in the use of 16 bit characters. + * This allows the handling of characters beyond the + * small ASCII character set and allows the utility to + * interoperate correctly with the rest of the Java + * runtime environment.</p> + *<p> + * Omissions from the C printf specification are + * numerous.
