Transforming Code

[Chase Becicka]

I am attempting to Transform an old Inventory Program into a banking Program as to save time writing a new program, its made up of three files a GUI, a controller (db and GUI middle man) and a db connection. I have almost everything working except a few errors in my GUI on my performGameDisplay method,I don't get why its giving me these errors because the variables that are producing the syntax problem are correctly declared in the other two files ive rewrote them a few times as to make sure I didnt have incompatable datatypes or something, so please if anyone knows why my variables arn't getting along with the compiler or if you know of any good refernces such as online tutorials I could refer to that would be a great help Heres my Code

import java.awt.*; //imports the Abstract Windows Toolkit Package
import java.awt.event.*; //imports the Abstract Windows Toolkit Package Event Package
import javax.swing.*; //imports the Swing GUI Package
import javax.swing.event.*; //imports Swing event Package
import java.text.*; //imports the text Package that assists in reading database information
import java.sql.*; //Imports the SQL Package which provides database manipulation and interfaces
 

public class inventFrame extends JFrame{ 
   public inventFrame(){
      setTitle("Teller Program"); //Set Title name in the top display bar of the code
      Toolkit tk = Toolkit.getDefaultToolkit();//Gets toolkit
      Dimension d = tk.getScreenSize();//Sets Boundiers for Frame size
      int width = 400, height = 375;
      setBounds((d.width - width)/2, (d.height - height)/2, width, height);
      setResizable(false);
