basic java

string text = "500";
 int num = int.Parse(text);
 Console.WriteLine(num);

  String text = "500";

        int num = int.Parse(text);
 System.out.println(num); 

-----------------------------------------------------------

  String text = "500"; 

           int num = int.Parse(text);//incorrect 
 int num = Integer.parseInt(text);//do this
 System.out.println(num);
