System.out.println("three=one+two ==>"+(one+two));
      
       System.out.println("three+=one ==>"+(three+one));
     
       
       
         System.out.println("three-=one ==>"+(three-one));
       System.out.println("three*=one ==>"+(three*one));
       System.out.println("three/=one ==>"+(three/one));
       System.out.println("three%=one ==>"+(three%one));
        
        哪里错了？
