然后看了下toUnsignedString函数,作用是int转换成对应的进制的字符串表示,先上代码: public static String toUnsignedString(long i, int radix) { if (i >= 0) return toString(i, radix); else { switch (radix) { case 2: return toBinaryStrin
* @see #parseUnsignedInt(String, int) * @see #toUnsignedString(int, int) * @since JDK1.0.2 */ public static String toBinaryString(int i) { return toUnsignedString0(i, 1); } /** * Convert the integer to an unsigned number. */ private static String toUnsignedString0(int val, int...
public static StringtoOctalString(int i) { return toUnsignedString(i, 3); } 这个地方的3就是因为转换为8进制,8 = 2 ^3,调用与16进制相同的方法。 将整数转换为二进制: public static StringtoBinaryString(int i) { return toUnsignedString(i, 1); } 这个地方的1同上,2 = 2^1,调用方法都是相...
}if(nm.startsWith("-", index) || nm.startsWith("+", index))thrownewNumberFormatException("Sign character in wrong position");try{ result = Integer.valueOf(nm.substring(index), radix);//底层调用valueOf(String str, int radix) --> parseInt(String str, int radix)result = negative ? Int...
ToBinaryString(Int64) Returns a string representation of the long argument as an unsigned integer in base 2. ToHexString(Int64) Returns a string representation of the long argument as an unsigned integer in base 16. ToOctalString(Int64) Returns a string representation of the long...

Installation Guide has been updated with changes to Installing With a Configuration File.Options related to string deduplication have been added to the java command tool page. String deduplication reduces the memory footprint of String objects on the Java heap by taking advantage of the fact that ...
