看了好多遍還是不知道那里錯了，請大神指教？
public class HelloWorld{
? ? public static void main(String[] args) {
? ? int one = 10 ;
? ? ? ? int two = 20 ;
? ? ? ? int three = 0 ;
? ? ? ?three=one+two;
? ? System.out.printf("three = one + two ==>" + three);
? ? ? ? three+=one;
? ? System.out.printf("three += one ==>"? + three);
? ? ? ? three-=one;
? ? System.out.printf("three -= one ==>"? + three);
? ? ? ? three*=one;
? ? System.out.printf("three *= one ==>"? + three);
? ? ? ? three/=one;

我給你改完了，你看看你的代碼和我寫的是不是一樣。注意兩點結(jié)尾的｝你有幾個。println這個單詞是否打?qū)α恕?/p>

+ three在一開始加一次就可以了吧。不用在每個打印里都加一次把。如果加的話，會重疊。
