при импорте Jpanel в другую Jpanel я хочу иметь размер Jpanel из класса Home такой же, как Jpanel из calss tstone

Question

при импорте Jpanel в другую Jpanel, я хочу, чтобы размер Jpanel из класса Home был таким же, как у Jpanel из calss tstone

это когда я запускаю приложение, он показывает Jpanel из класса Home внутри Jpanel из основного класса "tstone", но не одного и того же размера, я хочу иметь оба одинаковых размера благодаря alote

это класс tstone:

import java.awt.GraphicsEnvironment;
import javax.swing.JFrame;
import project.Dashboard;
import project.Home;


public class tstone extends javax.swing.JFrame {
Home main_home = new Home();

public tstone() {
    initComponents();
    tstone.this.setExtendedState(JFrame.MAXIMIZED_BOTH);
    GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
    tstone.this.setMaximizedBounds(env.getMaximumWindowBounds());
    this.setLocationRelativeTo(null);



    pane3.add(main_home.Forme_Home);
    pane3.setVisible(true);
 }
