Java 位运算符示例

下面的程序是一个简单示例，演示了位运算符。复制粘贴以下Java程序到Test.java文件中，然后编译和运行该程序 –

示例

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;       /* 15 = 1111 */
      System.out.println("a >> 2  = " + c );

      c = a >>> 2;      /* 15 = 0000 1111 */
      System.out.println("a >>> 2 = " + c );
   }
}

这将生成以下结果 −

输出

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