进制转换，十进制转为二进制、八进制、十六进制

package wzt;public class Bit1 {public static void main(String[] args) {int i=255;System.out.println(i);System.out.println(Integer.toBinaryString(i));//10转2System.out.println(Integer.toOctalString(i));//10转8System.out.println(Integer.toHexString(i));//10转16+System.out.println(0b11111111);//2转10System.out.println(010);//8转10System.out.println(0xff);//16转10System.out.println(0b101);//2转10}
