这样写对吗?
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==>"+(one+two));
System.out.println("three+=one==>"+(three+one));
System.out.println("three-=one==>"+(three+one-one));
System.out.println("three*=one==>"+(three*one));
System.out.println("three/=one==>"+(three*one/one));
System.out.println("three%=one==>"+three%one);
