I know people are probably gonna tell me to use layouts instead of this but for the project im doing I would really like to able to set the positioning myself.

The problem im having is that I have all the positioning and sizing correct in the panels but when I run the code it simply doesnt have either the dimensions or the positioning I set and I dont understand why.

import javax.swing.*;
import java.awt.*;

class MyFrame extends JFrame {
    MyFrame() {
        SwingUtilities.invokeLater(() -> {
            JPanel combatPanel = new JPanel();
            combatPanel.setLayout(null);
            combatPanel.setBounds(0,0,1380,805);
            combatPanel.setBackground(Color.darkGray);

            JPanel combatImage = new JPanel();
            combatImage.setLayout(null);
            combatImage.setBounds(0,0,1380,575);
            combatImage.setBackground(Color.black);

            JPanel combatActions  = new JPanel();
            combatActions.setLayout(null);
            combatActions.setBounds(0,575,480,230);
            combatActions.setBackground(Color.gray);

            JPanel combatActionInfo = new JPanel();
            combatActionInfo.setLayout(null);
            combatActionInfo.setBounds(480,575,900,115);
            combatActionInfo.setBackground(Color.lightGray);

            JPanel combatPlayerInfo = new JPanel();
            combatPlayerInfo.setLayout(null);
            combatPlayerInfo.setBounds(480,690,900,115);
            combatPlayerInfo.setBackground(Color.red);


            ImageIcon icon = new ImageIcon("image.png");

            this.setTitle("F&H 342"); // sets title of frame
            this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // exit out of application
            this.setResizable(false); // prevent frame from being resized
            this.setSize(1380, 805); // sets the x-dimension, and y-dimension of frame
            this.setVisible(true); // make frame visible
            this.getContentPane().setBackground(Color.yellow);
            this.setIconImage(icon.getImage());
            this.setLayout(null);

            combatPanel.add(combatImage);
            combatPanel.add(combatActions);
            combatPanel.add(combatActionInfo);
            combatPanel.add(combatPlayerInfo);
            this.add(combatPanel);
        });
    }
}

public class Main {
    public static void main(String[] args) {
        MyFrame myFrame = new MyFrame();
    }
}

what i was trying to do

Tried to make dimensions like in the image.
