Java位运算符示例

下面的简单示例程序演示了位运算符。复制并粘贴下面的Java程序于 Test.java 文件,并编译和运行这个程序:

public class Test {

  public static void main(String args[]) {
     int a = 60;	/* 60 = 0011 1100 */  
     int b = 13;	/* 13 = 0000 1101 */
     int c = 0;

     c = a & b;       /* 12 = 0000 1100 */ 
     System.out.println("a & b = " + c );

     c = a | b;       /* 61 = 0011 1101 */
     System.out.println("a | b = " + c );

     c = a ^ b;       /* 49 = 0011 0001 */
     System.out.println("a ^ b = " + c );

     c = ~a;          /*-61 = 1100 0011 */
     System.out.println("~a = " + c );

     c = a << 2;     /* 240 = 1111 0000 */
     System.out.println("a << 2 = " + c );

     c = a >> 2;     /* 215 = 1111 */
     System.out.println("a >> 2  = " + c );

     c = a >>> 2;     /* 215 = 0000 1111 */
     System.out.println("a >>> 2 = " + c );
  }
} 

这将产生以下结果:

a & b = 12
a | b = 61
a ^ b = 49
~a = -61
a << 2 = 240
a >> 15
a >>> 15
