【java】java中的 &= 和 |= 和 ^= 的区别

今日份代码：

public class MainMethod {
    public static void main(String[] args) {
        boolean flag = true;
        flag &= true;
        System.out.println("true	&=	true	==>	" + flag);
        flag = true;
        flag &= false;
        System.out.println("true	&=	false	==>	" + flag); 
        flag = false;
        flag &= true;
        System.out.println("false	&=	true	==>	" + flag); 
        flag = false;
        flag &= false;
        System.out.println("false	&=	false	==>	" + flag+"
"); 
        
        flag = true;
        flag |= true;
        System.out.println("true	|=	true	==>	" + flag);
        flag = true;
        flag |= false;
        System.out.println("true	|=	false	==>	" + flag); 
        flag = false;
        flag |= true;
        System.out.println("false	|=	true	==>	" + flag); 
        flag = false;
        flag |= false;
        System.out.println("false	|=	false	==>	" + flag+"
"); 
        
        System.out.println("^=  相同为假，不同为真");
        flag = true;
        flag ^= true;
        System.out.println("true	^=	true	==>	" + flag);
        flag = true;
        flag ^= false;
        System.out.println("true	^=	false	==>	" + flag); 
        flag = false;
        flag ^= true;
        System.out.println("false	^=	true	==>	" + flag); 
        flag = false;
        flag ^= false;
        System.out.println("false	^=	false	==>	" + flag); 
    }
}
