A SAMPLE APPLICATION DEVELOPMENT BY USING SWING COMPONENTS

//creating a shopping form

//here I am creating a sample form by using the JApplet class in the swings

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

public class MyForm extends JApplet implements ActionListener

{

//vars

JLabel n,a,i,lbl;

JTextField name;

JTextArea addr;

JList lst;

JButton b1,b2;

Object x[];

Container c;

String str="" ,str1="",str2="";

public void init()

{

//create frame and content pane

JFrame jf = new JFrame();

c=jf.getContentPane();

c.setBackground(Color.yellow);

c.setLayout(null);

jf.setSize(500,400);

jf.setTitle("MyForm");

jf.setVisible(true);

//heading

lbl=new JLabel();

lbl.setForeground(Color.red);

lbl.setFont(new Font("Dialog",Font.BOLD,36));

lbl.setText(" ONLINE SHOPPING");

lbl.setBounds(200,10,550,40);

c.add(lbl);

//label and text fields for name

n= new JLabel("Enter name:",JLabel.RIGHT);

name=new JTextField(20);

n.setBounds(50,50,150,40);

name.setBounds(200,50,200,40);

c.add(n);

c.add(name);

//Label and textArea for address

a=new JLabel("Enter address:",JLabel.RIGHT);

addr=new JTextArea(6,20);

a.setBounds(50,100,150,40);

addr.setBounds(200,100,200,150);

c.add(addr);

c.add(a);

//a Label and ListBox for user Selection

i=new JLabel("select Items:",JLabel.RIGHT);

String data[] ={"T-shirts","Trousers","shorts","Jeans"};

lst=new JList(data);

i.setBounds(50,270,150,40);

lst.setBounds(200,270,200,100);

c.add(i);

c.add(lst);

//Push Buttons

b1= new JButton("ok");

b2= new JButton("Cancel");

b1.setBounds(200,400,150,40);

b2.setBounds(400,400,70,40);

c.add(b1);

c.add(b2);

//add ActionListener to buttons

b1.addActionListener(this);

b2.addActionListener(this);

}

public void actionPerformed(ActionEvent ae)

{

str=ae.getActionCommand();

if(str.equals("ok"))

{

str1+=name.getText()+"\n";

str1+=addr.getText()+"\n";

x=lst.getSelectedValues();

for(int i=0;i<x.length;i++)

str2+=(String)x[i]+"\n";

//send the data into addr

addr.setText(str1+str2);

str1="";

str2="";

}

else

{

name.setText("");

addr.setText("");

lst.clearSelection();

}

//html file -1 it contains the above form class

<! This page contains My form class>

<html>

</applet>

</html>

Another animated application

// here I am designing the animate class by using the awt and applet conecpts

import java.awt.*;

import java.applet.*;

public class Animate extends Applet

{

public void init()

{

}

public void paint(Graphics g)

{

Image i = getImage(getDocumentBase(),"Gajanan.gif");

for(int x=0;x<800;x++)

{

g.drawImage(i,x,0,this);

try

{

Thread.sleep(20);

}

catch(InterruptedException ie)

{ }

}

//html file with animate.class

<! this page contains Animate class>

<html>

</applet>

</html>
