列举Java中的逻辑运算符  

int a = 20;
        int b = 15;
        int c = 10;

        if (a == b && b == c && c == a) {
            System.out.println(true);
        }else{
            System.out.println(false);
        }



int a = 20;
        int b = 15;
        int c = 10;

        if (a == b && b == c && c == a) {
            System.out.println(true);
        }else{
            System.out.println(false);
        }

 boolean a = true;
        boolean b = false;

        System.out.println(a || b);
