APJI-Lab3-Layout Manager, Swing Menu
Application Programming I
Module 3 – Layout Manager
Module 4 – Swing Menu Component
Lab Guide for Session 3
Session Objectives
In this session, you will be practicing with
Different types of Layout Manager:FlowLayout, BorderLayout, GridLayout
CardLayout, GroupLayout.
Menu component:JMenuBar, JMenu, JMenuItem, JCheckBoxMenuItem,
JRadioButtonMenuItem, JPopupHenu
JFileChooser and its subclasses
JToolBar
Part 1 – Getting started (30 minutes)
1. Create an application that shows 20 buttons in a frame using FlowLayout(10 minutes)
Scan the code first, type the code, compile, run and observe the result.
import java.awt.Container;
import java.awt.FlowLayout;
import javax.swing.JButton;
public class TestFlowLayout extends javax.swing.JFrame
{
/** Creates new form TestFlowLayout */
public TestFlowLayout() {
Container cp = getContentPane();
cp.setLayout(new FlowLayout());
for (int i = 0; i < 20; i++) {
cp.add(new JButton("Button " + i));
}
pack();
setDefaultCloseOperation(
javax.swing.WindowConstants.EXIT_ON_CLOSE);
}
public static void main(String args[]) {
new TestFlowLayout().setVisible(true);
}

}
2. Create an application that shows 5 buttons in a frame using BorderLayout(10 minutes)
Scan the code first, type the code, compile, run and observe the result.
import
import
import
import
java.awt.BorderLayout;
java.awt.Container;
javax.swing.JButton;
javax.swing.JFrame;
public class TestBorderLayout extends JFrame{
public TestBorderLayout() {
setLayout(new BorderLayout());
Container c= getContentPane();
c.add(new JButton("EAST"), BorderLayout.EAST);
c.add(new JButton("WEST"), BorderLayout.WEST);
c.add(new JButton("NORTH"), BorderLayout.NORTH);
c.add(new JButton("SOUTH"), BorderLayout.SOUTH);
c.add(new JButton("CENTER"), BorderLayout.CENTER);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pack();
}
public static void main(String[] args) {
new TestBorderLayout().setVisible(true);
}
}
3. Create an application with a frame and menu structure(10 minutes):
Subjects
Physics
Metaphysics
Astrophysics
Biology
Microbiology
Biotechnology
Chemistry

import javax.swing.*;
import java.awt.*;
public class MenuTest extends JFrame{
MenuTest() {
JMenuBar mb = new JMenuBar();
JMenu subjects = new JMenu("Subjects");
JMenu submenu1 = new JMenu("Physics");
submenu1.add(new JCheckBoxMenuItem("Metaphysics"));
submenu1.add(new JCheckBoxMenuItem("Astrophysics"));
subjects.add(submenu1);
submenu1 = new JMenu("Biology");
submenu1.add(new JCheckBoxMenuItem("Microbiology"));
submenu1.add(new JCheckBoxMenuItem("Biotechnology"));
subjects.add(submenu1);
submenu1 = new JMenu("Chemistry");
submenu1.add(new JCheckBoxMenuItem("Organic"));
submenu1.add(new JCheckBoxMenuItem("Inorganic"));
subjects.add(submenu1);
mb.add(subjects);
setJMenuBar(mb);
setTitle("MenuTest");
setSize(200,200);
}
public static void main(String[] args){
new MenuTest().setVisible(true);
}
}
Part 2 – Workshops (30 minutes)
Quickly look at workshops for Module 3 and Module 4 for reviewing basic steps
Try to compile, run and observe the output of sample code provided for related workshop.
Discuss with your class-mate and your instructor if needed.
Part 3 – Lab Assignment (60 minutes)
Do the assignment for Module 3 and Module 4 carefully. Discuss with your class-mates and
your instructor if needed.
