Please help me finish off this program

Hi, I am working on a program and can not seem to be able to finish it exactly. I am having problems at the end. Any help would be greatly appreciated.

Code:

-The problems come at the end with the 2 lines that have //. The first is say .class expect and the second line gives me the error cant find symbol, method setText(java.lang.string). When I compile without those lines it works but does not compute the other numbers, it does the first then stops.

The assignment is the following- Use a one-dimensional array to solve the following problem: Write an application that inputs five numbers, each between 10 and 100, inclusive. As each number is read, display it only if it's not a duplicate of a number already read. Provide for the "worst case" in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values input after the user enters each new value. Use a GUI with a textfield to enter each value and a text area to display the unique values.
Thank you for your time.

1) You don't convert a String to an int via String.valueOf(...) as this for doing the exact opposite -- converting an int (or other primitive) to a String. Consider using Integer.parseInt instead.

2) displayFinal is a JPanel, so the compiler is correct to complain that you can't call setText(...) on it since this method doesn't exist for JPanel, nor should it. Perhaps you want to call this on a JLabel or JTextField variable instead?
