Example of BoxLayout class with Y-AXIS

1. import java.awt.*;  
2. import javax.swing.*;  
3.   
4. public class BoxLayoutExample1 extends Frame {  
5.  Button buttons[];  
6.   
7.  public BoxLayoutExample1 () {  
8.    buttons = new Button [5];  
9.     
10.    for (int i = 0;i<5;i++) {  
11.       buttons[i] = new Button ("Button " + (i + 1));  
12.       add (buttons[i]);  
13.     }  
14.   
15. setLayout (new BoxLayout (this, BoxLayout.Y_AXIS));  
16. setSize(400,400);  
17. setVisible(true);  
18. }
