class BitTest {
    public static void main(String[] args) {
        int m = 12;
        int n = 5;
        System.out.println("m & n :" + (m & n));
        System.out.println("m | n :" + (m | n));
        System.out.println("m ^ n :" + (m ^ n));
    }
}

//1&1=1 否则0
//0|0=0 否则1
//1^1=0 0^0=0 1^0=1 0^1=1

运行结果：
m & n :4
m | n :13
m ^ n :9
