My iterator method is having trouble finding an entered record. The method I am using is this:

iterator = gamesList.listIterator();
int Code = Integer.parseInt(JOptionPane.showInputDialog("Enter Code:"));

boolean Found = false;

for (int i = 0; i < gamesList.size(); i++) 
{
    setMembers(iterator.next());
    if(obj.getId() == Code)
    {
        Found = true;
        break;
    }
}

if(Found == true)
{
    System.out.println("Success!");
}

This method is proven to work with other programs of this type.

What line is causing the null pointer exception? – Brian Schlenker May 21 '16 at 16:55
My guess is that you get a NPE because `getId()` returns a null `Integer` – May 21 '16 at 16:56
What is `obj`, did you checked if it's `null` – piyushj May 21 '16 at 17:00
It think the NullPointerException comes from your obj variable. Where do you initialize it? – tfosra May 21 '16 at 17:04
Obj is my variable for instantiating a java class – GipsyD May 21 '16 at 18:33
The error is at the if() statement – GipsyD May 21 '16 at 18:34
