AWT-Abstract Window Toolkit

Class BorderLayout

The BorderLayout is used to arrange the components in five regions: North, South, East, West and Center.
Each region (area) may contain one component only.
It is the default layout of frame window.
While adding component we must specify its location(region) by calling method add( Component , Location ) of class Container.
Location can be North, South, East, West or Center.

For ex:

        b1=new Button("OK");
        add(b1,"North");
        b2=new Button("Cancel");
        add(b2,"South");

Constructors

BorderLayout()

BorderLayout(int hgap, int vgap)

#Design a frame with 2 buttons OK and Cancel at top and bottom.

 import java.awt.*;
 class MyFrame extends Frame 
 {
    Button b1,b2;
    public MyFrame()
    {
        BorderLayout lm=new BorderLayout();
        this.setLayout(lm);
        b1=new Button("OK");
        b2=new Button("Cancel");
        add(b1,"North");
        add(b2,"South");
    }
 } 
 class demo
 {
    public static void main(String args[])
    {
        MyFrame frm=new MyFrame();
        frm.setSize(400,300);
        frm.setVisible(true);
    }
 }
