JList and JPanels

[JetsYanks]

Hey everyone, Ive recently started working with Java and have a basic grasp to it, but I hit a problem. When I enter a JList into a JPanel, the list will show up, but any other JPanels I add will not show up(when I run void-main option in BlueJ), and Im not sure as to what Im doing wrong because I'm having no Compiling Issues.

Heres an example of my code-

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

public class Test extends JFrame {
    
    private String[] stringNames = {"Test1", 
                                  "Test2", 
                                  "Test3", 
                                  "Test4",
                                  "Test5",
                                  "Test6",
                                  "Test7",
                                  "Test8",
                                  "Test9",
                                  "Test10",
                                  "Test11"};
     private JList jlist = new JList(stringNames); 
     private JTextField jtext = new JTextField("--Welcome--");
     
     public static void main(String[] args) {
         Test frame = new Test();
         frame.setSize(650, 550);
         frame.setTitle("Welcome to Java");
         frame.setLocationRelativeTo(null);
         frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         frame.setVisible(true);
        }
        public Test() {
            Container container = getContentPane();
            getContentPane().setLayout(new FlowLayout());
    

            getContentPane().add(jlist);
            getContentPane().add(jtext);
            
            JList jlist = new JList(stringNames);
            JPanel p1 = new JPanel();
            p1.add(jlist);
                
            JPanel p2 = new JPanel();
            JPanel p3 = new JPanel();
            p2.add(jtext);
                p2.add(p1, BorderLayout.WEST);
                p3.add(p2, BorderLayout.EAST);
        
        }
}

What about JScrollPane? have you try to use it for the JList?

I think he wants add more than one JPanel on a frame.

yah...

@ OP, have a look at the getContentPane().add(something)...
only jlist and jtext are added...

You can bring them at the bottom.
and add the panels like what you did in jlist
