Question

Ok, here’s the issue!

I have a class GetStuff

public class GetStuff {

   public GetStuff(String data) {
       // stuff
   }

}

In this class I have a method getMyStuff() which calls a second method:

getAllMyStuff();

Now, I want to extend my class so I’ll make a:

public class GetSecondStuff extends GetStuff {

      public GetSecondStuff(String data, int newData) {
           super(data);
      }

}

in this 2nd class I will override my getAllMyStuffMethod, but inside this method I’ll need to use the newData parameter from the constructor:

private String getAllMyStuffMethod() {
   if (newData==0) // do something
}

How can I use here newData ? 🙁

Answer 1

public class GetStuff {
    public GetStuff(String data) {
        System.out.println(data);
    }
}

public class GetSecondStuff extends GetStuff {
    private int newData;

    public GetSecondStuff(String data, int newData) {
        super(data);
        this.newData = newData;


        data = "GetSecondStuff";        
        System.out.println(data);

        System.out.println(getAllMyStuffMethod());

    }

    private String getAllMyStuffMethod() {
        String ret=null;
          if (this.newData==0)
              ret="0";
          else
              ret="1";

        return "new data : "+ret;
    }
}

public class main {

    public static void main(String[] args) {        

        GetSecondStuff gf2 = new GetSecondStuff("GetStuff",1);      
    }

}

OUTPUT :

GetStuff

GetSecondStuff

new data : 1
