?int one = 10 ;

? ? ? ? int three = 0 ;

? ? ? ? three = one +two;

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

? ? ? ? three+=one;

? ? ? ? three-=one;

? ? ? ? three*=one;

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

? ? ? ? three/=one;

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

? ? ? ? three%=one;

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

? ? ? ??

這段代碼的最好為什么three%=one的結果是0呢，three此時為30，30%10因該為3才對啊
