public class Mobile extends Gadget
{
    // instance variabrles 
    private int creditRemaining;

    /**
     * Constructor for objects of class Mobile
     */
    
    public Mobile(int creditRemaining, int theWeight, double thePrice, String theModel, String theSize);
    {
           super(theWeight, thePrice, theModel,theSize);        
           creditRemaining = RemainingCredit; 
    } 

this is the coding for the subclass, the superclass of gadget
can someone please tell me where I am going wrong, as I am new to this.

thank you :)

It is a bit hard to tell with a description of what the problem is.

But a guess:

creditRemaining = RemainingCredit;

->

this.creditRemaining = creditRemaining;

Obviously you have a problem with your variable naming. Do you 
understand what you are doing? You can name a passed parameter 
and the instance variable the same if you use the prefix "this" 
to distinguish between them, as Arne demonstrates. You might 
want to review the online tutorial...
