【散分贴】一道运算符的JAVA题，求解析

Question

int a=-67,b=116,c=78;
int d=~a|b&c;
System.out.println(d);请高手们 详细指导指导一下，本人基础差一点

Answer 1

位运算啊。这样就看清楚了：
（整数32位，~是按位取反，&是按位与，|是按位或） int a=-67,b=116,c=78;
int d=~a|b&c;
System.out.println(Integer.toBinaryString(a));
System.out.println("0000000000000000000000000" + Integer.toBinaryString(~a));
System.out.println("0000000000000000000000000" + Integer.toBinaryString(b));
System.out.println("0000000000000000000000000" + Integer.toBinaryString(c));
System.out.println("0000000000000000000000000" + Integer.toBinaryString(b&c));
System.out.println("0000000000000000000000000" + Integer.toBinaryString(d));
System.out.println(d);

Answer 2

-67:111...1011 1101 
116:000...0111 0100
78: 000...0100 1110116&78: 000...0100 0100
~67:    000...0100 0010|:      000...0100 0110所以结果是70，我dt了，竟然真的自己算了遍
