請問這兩組代碼有什么不同的意義？為什么會得到不同的結果？
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);
???????
???????

意義是不同的，計算機在編譯的時候是按照順序的，所以你看到第一組代碼的輸出three的值是不一樣的，但是第二組代碼的輸出值都是同一個
