不要加int 再次声明了，声明一次就可以额

不要重复声明变量的数据类型，声明一次就够了。three声明了好几回数据类型。就好比一个人，都声明是男人，反复声明他是男人没多大意义。
参考代码
public class HelloWorld{ public static void main(String[] args) { int one = 10 ; int two = 20 ; 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); } }
