BorderLayout as Layout Manager in Java

[ASHGARD8]

This tutorial is about the BorderLayout as Layout Manager in Java. A BorderLayout is a layout where it has a rectangular screen area divided into five regions - North, South, East, West, and Center position regions.

So, now let's start this tutorial!

1. Open JCreator or NetBeans and make a java program with a file name of borderLayout.java.

2. Import the following packages:

1. import
   
   java.awt.*
   
   ;
   
   //used to access the BorderLayout class
   
2. import
   
   javax.swing.*
   
   ;
   
   //used to access the JFrame and JButton class
   

3. Initialize your variable in your Main, variable frame for JFrame, and 4 buttons namely btnNorth, btnSouth, btnEast, and btnWest as JButton.

1. JFrame
   
   frame =
   
   new
   
   JFrame
   
   (
   
   "BorderLayout as Layout Manager"
   
   )
   
   ;
   
2. JButton
   
   btnNorth, btnSouth, btnEast, btnWest;
   
3. 
   
4. btnNorth =
   
   new
   
   JButton
   
   (
   
   "North"
   
   )
   
   ;
   
5. btnSouth =
   
   new
   
   JButton
   
   (
   
   "South"
   
   )
   
   ;
   
6. btnEast =
   
   new
   
   JButton
   
   (
   
   "East"
   
   )
   
   ;
   
7. btnWest =
   
   new
   
   JButton
   
   (
   
   "West"
   
   )
   
   ;
   

4. To set your program layout to BorderLayout, we will use the setLayout method of the JFrame and put inside the BorderLayout class on it.

1. frame.getContentPane
   
   (
   
   )
   
   .setLayout
   
   (
   
   new
   
   BorderLayout
   
   (
   
   )
   
   )
   
   ;
   

Then, we will add the four buttons into the frame with a different positions in a BorderLayout.

1. frame.getContentPane
   
   (
   
   )
   
   .add
   
   (
   
   btnNorth, BorderLayout
   
   .NORTH
   
   )
   
   ;
   
2. frame.getContentPane
   
   (
   
   )
   
   .add
   
   (
   
   btnSouth, BorderLayout
   
   .SOUTH
   
   )
   
   ;
   
3. frame.getContentPane
   
   (
   
   )
   
   .add
   
   (
   
   btnEast, BorderLayout
   
   .EAST
   
   )
   
   ;
   
4. frame.getContentPane
   
   (
   
   )
   
   .add
   
   (
   
   btnWest, BorderLayout
   
   .WEST
   
   )
   
   ;
   

The BorderLayout.NORTH assumes that the button is in the top position, BorderLayout.SOUTH in the bottom, BorderLayout.EAST in the left, and BorderLayout.WEST is in the right position, respectively.

5. Lastly, set the size, visibility, and the close operation of the frame. Have this code below:

1. frame.setDefaultCloseOperation
   
   (
   
   JFrame
   
   .EXIT_ON_CLOSE
   
   )
   
   ;
   
2. frame.setSize
   
   (
   
   200
   
   , 100
   
   )
   
   ;
   
3. frame.setVisible
   
   (
   
   true
   
   )
   
   ;
   

Output:

Here's the full code of this tutorial:

1. import
   
   java.awt.*
   
   ;
   
   //used to access the BorderLayout class
   
2. import
   
   javax.swing.*
   
   ;
   
   //used to access the JFrame and JButton class
   
3. 
   
4. public
   
   class
   
   borderLayout{
   
5. 
   
6. public
   
   static

   {
