為什么 three = one + two；不能int three = one + two 嗎
? ? ? ? int three = one + two;
? ? ? ? System.out.println("three = one + two ==>" + three);
? ? ? ? int three += one;
? ? ? ? System.out.println("three += one ==>" + three);
? ? ? ? int three -= one;
? ? ? ? System.out.println("three -= one ==>" + three);
? ? ? ? int three *= one;
? ? ? ? System.out.println("three *= one ==>" + three);
? ? ? ? int three /= one;
? ? ? ? System.out.println("three /= one ==>" + three);
? ? ? ? int three %= one;
? ? ? ? System.out.println("three %= one==>" + three);
為什么不要加int。。。。。

three在那之前已經用int定義過了、
