        boolean a = true;
        boolean b = false;

        System.out.println("a && b:"+(a&&b));//逻辑与运算，真真才真
        System.out.println("a || b:"+(a||b));//或运算，有真则真
        System.out.println("!(a && b):"+!(a&&b));//真则假 假则真

        //短路运算
        //：如果为假 则后面不会执行
        // eg
        int c = 4;
        boolean d = (c<4)&&(++c<10);
        System.out.println(c);
        System.out.println(d);
