<DL>
<DD>Creates a string representation of the first argument in the radix specified by the second argument. <p> If the radix is smaller than <code>Character.MIN_RADIX</code> or larger than <code>Character.MAX_RADIX</code>, then the radix <code>10</code> is used instead. <p> If the first argument is negative, the first element of the result is the ASCII minus character <code>'-'</code> (<tt>'\u002d'</tt>). If the first argument is not negative, no sign character appears in the result. <p> The remaining characters of the result represent the magnitude of the first argument. If the magnitude is zero, it is represented by a single zero character <tt>'0'</tt> (<tt>'\u0030'</tt>); otherwise, the first character of the representation of the magnitude will not be the zero character. The following ASCII characters are used as digits: <blockquote><pre> 0123456789abcdefghijklmnopqrstuvwxyz </pre></blockquote> These are <tt>'\u0030'</tt> through <tt>'\u0039'</tt> and <tt>'\u0061'</tt> through <tt>'\u007a'</tt>. If the <tt>radix</tt> is <var>N</var>, then the first <var>N</var> of these characters are used as radix-<var>N</var> digits in the order shown. Thus, the digits for hexadecimal (radix 16) are <blockquote><pre> <tt>0123456789abcdef</tt>. </pre></blockquote><DD><DL>

<DD>Creates a string representation of the integer argument as an unsigned integer in base 16. <p> The unsigned integer value is the argument plus 2<sup>32</sup> if the argument is negative; otherwise, it is equal to the argument. This value is converted to a string of ASCII digits in hexadecimal (base 16) with no extra leading <code>0</code>s. If the unsigned magnitude is zero, it is represented by a single zero character <tt>'0'</tt> (<tt>'\u0030'</tt>); otherwise, the first character of the representation of the unsigned magnitude will not be the zero character. The following characters are used as hexadecimal digits: <blockquote><pre> 0123456789abcdef </pre></blockquote> These are the characters <tt>'\u0030'</tt> through <tt>'\u0039'</tt> and <tt>'u\0039'</tt> through <tt>'\u0066'</tt>.<DD><DL>

This value is converted to a string of ASCII digits in octal (base 8) with no extra leading <code>0</code>s. <p> If the unsigned magnitude is zero, it is represented by a single zero character <tt>'0'</tt> (<tt>'\u0030'</tt>); otherwise, the first character of the representation of the unsigned magnitude will not be the zero character.

<DD>Creates a string representation of the integer argument as an unsigned integer in base 2. <p> The unsigned integer value is the argument plus 2<sup>32</sup>if the argument is negative; otherwise it is equal to the argument. This value is converted to a string of ASCII digits in binary (base 2) with no extra leading <code>0</code>s. If the unsigned magnitude is zero, it is represented by a single zero character <tt>'0'</tt> (<tt>'\u0030'</tt>); otherwise, the first character of the representation of the unsigned magnitude will not be the zero character.

The characters in the string must all be digits of the specified radix (as determined by whether <A HREF="../../java/lang/Character.html#digit(char, int)"><CODE>Character.digit(char, int)</CODE></A> returns a nonnegative value), except that the first character may be an ASCII minus sign <code>'-'</code> (<code>'\u002d'</code>) to indicate a negative value. The resulting integer value is returned. <p> An exception of type <tt>NumberFormatException</tt> is thrown if any of the following situations occurs:⌨️ 快捷键说明
