哪里错了帮我看下 谢谢
public class HelloWorld{
public static void main(String[] args) {
int one = 10 ;
int two = 20 ;
int three = 0 ;
three = one + two;
System.out.printlh("three = one + two ==>) " + three );
three += one ;
System.out.printlh("three += one ==>" + three );
three -= one ;
System.out.printlh("three -= one ==>" + three );
three *= one ;
System.out.printlh("three *= one ==>" + three );
three /= one ;
System.out.printlh("three /= one ==>" + three );
three %= one ;
System.out.printlh("three %= one ==>" + three );
