为什么 three = one + two；不能int three = one + two 吗
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);
为什么不要加int。。。。。
