上面的回答是对的

总的来说是定义算式再输出结果

int three = 0 ;

        three=one+two;

        System.out.println("three=one+two==>"+three);

        three+=one;

        System.out.println("three+=one==>"+three);

        three-=one;

        System.out.println("three-=one==>"+three);

        three*=one;

        System.out.println("three*=one==>"+three);

        three/=one;

        System.out.println("three/=one==>"+three);

        three%=one;

        System.out.println("three%=one==>"+three);

    }

}
