Java位運算符示例
下麵的簡單示例程序演示了位運算符。複製並粘貼下麵的Java程序於 Test.java 文件,並編譯和運行這個程序:
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 ); } }
這將產生以下結果:
a & b = 12 a | b = 61 a ^ b = 49 ~a = -61 a << 2 = 240 a >> 15 a >>> 15
