JLabel not showing in painted background

I have put a background image using "paint" and as I've tried to add a Jlabel it is not showing upon running. Here's my code and screenshots.

JLABEL not Showing (Upper Left)
I have tried removing the painted background image and it worked however I also need that background image to be there.

Can't seem to be able to move my objects using java

I seem to be unable to move any objects I bring into my class, my other classes seem to be functional when I set bounds, but not this one.
I'm wondering why it isn't working and functionally like my other classes.
Some of the bounds are extreme as that's me making sure I can notice if any of the objects are moving; which they are not.

no content in Jframe java

i have two jframes in my app, Addnmember.java and Frame1.java
Frame1 is the main Jframe,
i want when someone presses the Add button, the Addmember will be shown, i have done this with this code, and every thing is fine:
AddB.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
frame.dispose();
AddMember addmem = new AddMember();
addmem.setVisible(true);
}
});
But in the new Jframe, i want to come back again when Done Bt is selected, i have done this whit this code:
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
//dispose();
Frame1 addmem = new Frame1();
addmem.setVisible(true);
}

thanks.

As to why your second Frame1 shows no data, I'm not 100% sure, but perhaps it has something to do with your failure to close your database connection. Regardless, it seems wasteful and even potentially dangerous to want to gather the database data twice when you've already obtained it once, and to create your Frame1 GUI twice when you've already created it once.
You should re-design your GUI. The main JFrame GUI should remain visible, and the Frame1 window should be a modal JDialog. As a modal dialog, it will prevent users from being able to interact with the parent JFrame until the dialog is no longer visible.
Note that to get started requires only a few changes:
in Frame1.java
AddB.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
// frame.dispose();
AddMember addmem = new AddMember(Frame1.this); // !!
addmem.setVisible(true);
}
});
in AddMember.java
class AddMember extends JDialog {
public AddMember(JFrame frame) {
super(frame, "", ModalityType.APPLICATION_MODAL);
setTitle("\u0627\u0641\u0632\u0648\u062F\u0646 \u0639\u0636\u0648 \u062C\u062F\u06CC\u062F");
// !! setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
// dispose();
dispose(); // !!
// !! Frame1 addmem = new Frame1();
// addmem.setVisible(true);
}
});
Also, you'll want to avoid null layouts and setBounds(...) as this will lead to very rigid, hard to debug and improve programs.

How to close second JFrame without terminating program

How do I dispose my second frame while retaining my MainFrame?
I have a JFrame( CCurrencyConverterFrame) that I call from the Main Frame.
JMenuItem mntmCurrencyConverter = new JMenuItem("Currency Converter");
mntmCurrencyConverter.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
CCurrencyConverterFrame frame = new CCurrencyConverterFrame();
myFrame = frame;
JPanel contentPane = new CCurrencyConverter(myFrame);
frame.setContentPane(contentPane);
frame.setVisible(true);
}
});
In CCurrencyConverterFrame.java,
public CCurrencyConverterFrame() {
setFont(new Font("Dialog", Font.BOLD, 12));
getContentPane().setFont(new Font("Tahoma", Font.BOLD, 16));
setTitle("Currency Converter ");
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setBounds(100, 100, 469, 470);
//Center
setLocationRelativeTo(null) ;
}
I have tried using JFrame.HIDE_ON_CLOSE but it still terminates my application. What can I do to resolve this?

Calling JPanel from another JPanel

I know this is ill advised but I am using absolute layout and trying to go from panel to panel and was curious how to do this.
public class Mainscreen extends JFrame {
private JPanel Home;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Mainscreen frame = new Mainscreen();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
public Mainscreen() {
final Dataentrylog DEL = new Dataentrylog();
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setResizable(false);
setBounds(100, 100, 618, 373);
Home = new JPanel();
Home.setBackground(new Color(255, 250, 250));
Home.setBorder(new LineBorder(Color.DARK_GRAY, 1, true));
setContentPane(Home);
Home.setLayout(null);
JButton btnNewButton = new JButton("Data Entry login");
btnNewButton.setFont(new Font("Tahoma", Font.PLAIN, 14));
btnNewButton.setForeground(new Color(0, 0, 0));
btnNewButton.setBackground(UIManager.getColor("Menu.selectionBackground"));
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
Home.setVisible(false);
setContentPane(DEL);
setLayout(null);
}
});
btnNewButton.setBounds(44, 214, 204, 61);
Home.add(btnNewButton);
}
}
Calling this JPanel which works
import java.awt.EventQueue;
public class Dataentrylog extends JPanel {
public Dataentrylog() {
setBounds(100, 100, 618, 373);
setBackground(new Color(255, 250, 250));
setBorder(new LineBorder(Color.DARK_GRAY, 1, true));
setLayout(null);
DEadmin DEA = new Deadmin();
final JButton btnSignIn = new JButton("Sign in");
btnSignIn.setFont(new Font("Tahoma", Font.PLAIN, 14));
btnSignIn.setBackground(UIManager.getColor("EditorPane.selectionBackground"));
btnSignIn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
}
});
btnSignIn.setBounds(226, 282, 153, 52);
add(btnSignIn);
}
}
While this works if I try an call another JPanel from Dataentry log the JFrame is blank. What can I do to call another JPanel? Any help would be great. Also, I know that layoutmanagers are the norm but for what I had to do I wasn't able to find anything that worked so I choose to use null despite my best judgement. THANKS!

Intialization of Dataentrylog should be like this
final Dataentrylog DEL = new Dataentrylog(this);
we have to pass the parent jframe.
public class Dataentrylog extends JPanel {
public Dataentrylog(final JFrame parent ) {
setBounds(100, 100, 618, 373);
setBackground(new Color(255, 250, 250));
setBorder(new LineBorder(Color.DARK_GRAY, 1, true));
final JButton btnSignIn = new JButton("Sign in");
btnSignIn.setFont(new Font("Tahoma", Font.PLAIN, 14));
btnSignIn.setBackground(UIManager.getColor("EditorPane.selectionBackground"));
btnSignIn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
setVisible(false);
JPanel panel = new JPanel();
panel.add(new JButton("Solved"));
parent.setContentPane(panel);
}
});
btnSignIn.setBounds(226, 282, 153, 52);
add(btnSignIn);
}
}
