Simple gui

Hello i am trying to produce a gui which with a textarea that takes over half the length of a frame and half its depth. I have produced this code and at present it only is setting the textarea to a third at most of the length of the frame. If anyone knows how to alter this behavior it would be appreciated. I am also looking at adding other components to the bottom half of the frame - is my approach the best way or is there a better approach. Heres my code so far

Code:

---

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


public class Serverside1 extends JFrame
{

private JFrame window;

public Serverside1()
{

    window = new JFrame("Network Packet Sniffer");
    window.setSize(700,500);
    window.setVisible(true);
    window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JPanel panel = new JPanel();
 
    TextArea text = new TextArea("Network packets will he here",18, 30, TextArea.SCROLLBARS_NONE);
    panel.add(text);
    window.getContentPane().add(panel);
    window.show();
     
   
 
  }
public static void main(String[] args){
Serverside1 s = new Serverside1();
}
}

Thankyou.

You haven't told Swing that you want it to be that size. How should it know?

Investigate the method .setPreferredSize().
