The "X" format specifier converts a numeric value to a hexadecimal (base 16) string representation. The precision specifier determines the minimum number of digits returned. If no precision specifier is supplied, the minimum number of digits needed to represent the value is returned; otherwise, t...
// 通过 ofDelimiter 方法创建HexFormat,指定分隔符HexFormat format=HexFormat.ofDelimiter(":");String hex=format.formatHex("hello springdoc.cn".getBytes());System.out.println("Hex="+hex);byte[]bytes=format.parseHex(hex);System.out.println("bytes="+new String(bytes));// 获取分隔符Stringdeli...
Let’s now look at a Java code example that demonstrates the conversion of a hexadecimal number to decimal using theString.formatmethod: publicclassHexToDecimalConverter{publicstaticinthexToDec(Stringhex){returnInteger.parseInt(hex,16);}publicstaticvoidmain(String[]args){StringhexNumber="1A";intdeci...

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 toBinaryString(i); ...

Java String format width Thewidthfield is the minimum number of characters to be written to the output. It cannot be used together with the line separator. Main.java void main() { System.out.println(1); System.out.println(16); System.out.println(1655); ...
("X") format specifier converts a number to a string of hexadecimal digits. The case of the format specifier indicates whether to use uppercase or lowercase characters for hexadecimal digits that are greater than 9. For example, use "X" to produce "ABCDEF", and "x" to produce "abcdef...
