Answer 1

Ive tried many of the things that search suggested but none of them pertained enough to what i am doing for it to work. Here is my code:package gameFunctions;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class loginScreen extends JFrame implements ActionListener
     JTextField USERNAME, Username, PASSWORD, Password; // yeah i know, bad practice but there is some logic to the names relative to capitalization
     String username, password;
     JButton LOGIN;
     Dimension res = Toolkit.getDefaultToolkit().getScreenSize();
     ImageIcon background = new ImageIcon("C:\\FileTesting\\testImage.jpg");;
     JPanel pane;
public static void main(String[] args)
          loginScreen frame = new loginScreen();
          frame.setVisible(true);
public loginScreen()
          Container c = getContentPane();
          setSize(400, 300);
          setLocation((int)res.getWidth()/2-getWidth()/2, (int)res.getHeight()/2-getHeight()/2);
          setResizable(false);
          setLayout(null);
          pane = new JPanel();
          pane.setSize(getWidth(), getHeight());
          pane.setLayout(null);
          c.add(pane);
          USERNAME = new JTextField("Username:");
          USERNAME.setSize(68,25);
          USERNAME.setLocation(getWidth()/2-USERNAME.getWidth()/2-80, getHeight()/2-USERNAME.getHeight()/2-50);
          USERNAME.setEditable(false);
          pane.add(USERNAME);
          PASSWORD = new JTextField("Password:");
          PASSWORD.setSize(68,25);
          PASSWORD.setLocation(USERNAME.getX(), USERNAME.getY()+30);
          PASSWORD.setEditable(false);
          pane.add(PASSWORD);
          Username = new JTextField();
          Username.setSize(150,25);
          Username.setLocation(USERNAME.getX()+USERNAME.getWidth()+5, USERNAME.getY());
          Username.setEditable(true);
          pane.add(Username);
          Password = new JTextField();
          Password.setSize(150,25);
          Password.setLocation(Username.getX(), Username.getY()+30);
          Password.setEditable(false); // because im not working with PW's yet
          pane.add(Password);
          LOGIN = new JButton("LOGIN");
          LOGIN.setSize(80,30);
          LOGIN.setLocation(getWidth()/2-LOGIN.getWidth()/2, PASSWORD.getY()+30);
          pane.add(LOGIN);
          setDefaultCloseOperation(EXIT_ON_CLOSE);
public void actionPerformed(ActionEvent event)
}i want "pane" to be the image of "background" imageIcon is the only thing that works like this because i dont know how to use straight up "Image". everything works if i set the ImageIcon "background" to be the background of JButton "LOGIN"
any help would be greatly appreciated
