為什么不能運行呢？
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 = onr + two==>"+ three);
??????? three+=one;
??????? System.out.println("three += one ==>" + three);
??????? three-=one;
??????? System.out.println("three -= one ==>" + three);
??????? three*=one;
??????? System.out.ptintln("three *= one ==>" + three);
??????? three/=one;
??????? System.out.println("three /= one ==>" + three);
??????? three%=one;
??????? System.out.println("three %= one ==>" + three);
??????? }
??????? }

第7行one寫錯了，第13行println寫錯了，細心一點就好啦

System.out.println("three?=?one?+?two?==>"+(three=one+two));????????System.out.println("three?+=?one?==>"+(three?+=one));????????System.out.println("three?-=?one?==>"+(three?-=one));????????System.out.println("three?*=?one?==>"+(three?*=one));????????System.out.println("three?%=?one?==>"+(three?%=one));2018-09-19
還有你的第四個println也寫錯了呢，細心點哦，加油！

?System.out.println("three = onr + two==>"+ three);
你的one寫錯了吧，改了試試
