New to Java

public class Stuff {
     public static final int MY_CONSTANT = 5;
     public static int doStuff(int x){ return (x++)*x;}
}
import xcom.Stuff.*;
import java.lang.System.out;
class User {
   public static void main(String[] args){
   new User().go();
   }
   void go(){out.println(doStuff(MY_CONSTANT));}
}

Will the above code compile?
can be call a static method without mentioning the class name?
