求助哪里有問題？
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)；?
? ??
}
}
執行總是出錯，why？？？

恩，分號輸入錯了

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);
}
}
除了第一個輸出使用英文分號;????后面幾個都是用中文分號；。
