System.out.println(Integer.valueOf(0x10,16));
16

System.out.println("10\u7684\u4e8c\u8fdb\u5236="+Integer.toBinaryString(10));
System.out.println("10\u7684\u516b\u8fdb\u5236="+Integer.toOctalString(10));
System.out.println("10\u7684\u5341\u516d\u8fdb\u5236="+Integer.toHexString(10));
10\u7684\u4e8c\u8fdb\u5236=1010
10\u7684\u516b\u8fdb\u5236=12
10\u7684\u5341\u516d\u8fdb\u5236=a

var w=function(s){
document.write(''+s)
};
\u8f6c\u6362\u65b9\u6cd5\uff1a
w(parseInt(x,16));

举例：
System.out.print(Integer.parseInt("F", 16));)；
结果就是：15。
