What does the following print (assuming it compiles, which it does):

public class StrungOut {

      public static void main(String[] args) {

            String s = new String("Hello world");

            System.out.println(s);

      }

}

class String{

      private final java.lang.String s;

      public String(java.lang.String s){

            this.s = s;

      }

      public java.lang.String toString(){

            return s;

      }

}
