求指教，為什么顯示全是Three?
public class HelloWorld{
? ? public static void main(String[] args) {
? ?int one = 10 ;
? ? ? ? int two = 20 ;
? ? ? ? int three = 0 ;
? ? ? ? int three0 =one+two;
? ? ? ? System.out.println("three");three += one;
? ? ? ? System.out.println("three");three += one;
? ? ? ? System.out.println("three");three -= one;
? ? ? ? System.out.println("three");three *= one;
? ? ? ? System.out.println("three");three /= one;
? ? ? ? System.out.println("three");three %= one;
? ? ? ??
這樣對(duì)嗎？為什么顯示出來全是three?

因?yàn)槟爿敵龊瘮?shù)里的three是字符串，注意"three",表示你這里是一個(gè)字符串常量。去掉""后，就是變量了，就能顯示變量three的值
