JWindow and JFrame Component in Java

Submitted by donbermoy on Wednesday, November 26, 2014 - 09:58.

This is a tutorial in which we will going to create a program that will have a JWindow and JFrame Component in Java. We will first differentiate the two components. The JFrame can be a container of other components, has title and border, and has buttons for minimize, maximize, and close. Unlike JFrame, a JWindow can also hold other components but it has no title and border, and no minimize, maximize, and close button. So, now let's start this tutorial! 1. Open JCreator or NetBeans and make a java program with a file name of jWindowComponent.java. 2. Import the following packages:

import javax.swing.*; // used to access the JFrame, JWindow, and JPanel class
import java.awt.*; // used to access the FlowLayout class

3. Initialize your variable in your Main, variable frame for JFrame, variable window for JWindow, and variable panel for JPanel.

    JFrame frame = new JFrame("This is a Frame");
    JWindow window = new JWindow();
    JPanel panel = new JPanel();

4. We will add the JPanel component into the window, and it will have a default BorderLayout of Center position.

window.getContentPane().add(panel, "Center");

Now, we will create a FlowLayout for the panel and a Label inside the panel.

    panel.setLayout(new FlowLayout());
    panel.add(new Label("This is a Window"));

5. Lastly, we will set the size and location of the Frame and the Window.

    frame.setSize(300, 300);
    frame.setLocation(100, 100);
    
    window.setSize(300, 300);
    window.setLocation(500, 100);

Then, we will set the visibility to True for the two components to be seen by the user.

    frame.setVisible(true);
    window.setVisible(true);

Frame: output

Window: output

Output: output

Here's the full code of this tutorial:

import javax.swing.*; // used to access the JFrame, JWindow, and JPanel class
import java.awt.*; // used to access the FlowLayout class
 
 
public class jWindowComponent {
  public static void main(String[] args) {
    JFrame frame = new JFrame("This is a Frame");
    JWindow window = new JWindow();
    JPanel panel = new JPanel();
    
    window.getContentPane().add(panel, "Center");
 
    panel.setLayout(new FlowLayout());
    panel.add(new Label("This is a Window"));
    
    frame.setSize(300, 300);
    frame.setLocation(100, 100);
    
    window.setSize(300, 300);
    window.setLocation(500, 100);
    
    frame.setVisible(true);
    window.setVisible(true);
  }
}
