DEMO ACTION & KEY

 DEMO ACTION;

Contoh program demo action;

import java.awt.*;

import javax.swing.*;

import java.awt.event.*;

public class DemoAction  extends JFrame {

    private JButton BTNsimpan =new JButton("Simpan"),

BTNclear =new JButton("Clear");

private JLabel LBLsimpan =new JLabel("jihan nabela"),

LBLclear =new JLabel("Data Anda Terhapus");

DemoAction(){

super("Demo Action Listener");

JPanel Panel1 =new JPanel();

Panel1.setLayout(new FlowLayout());

Panel1.add(BTNsimpan);

Panel1.add(BTNclear);

getContentPane().add(Panel1);

setSize(200,150);

 setDefaultCloseOperation(EXIT_ON_CLOSE);

BTNclear.addActionListener(new ActionListener(){

public void actionPerformed (ActionEvent evn){

BTNsimpan.setVisible(false);

BTNclear.setVisible(false);

LBLclear.setVisible(true);

Panel1.add(LBLclear);

BTNsimpan.setEnabled(false);

}

});

BTNsimpan.addActionListener(new ActionListener(){

public void actionPerformed (ActionEvent evn){

BTNsimpan.setVisible(false);

BTNclear.setVisible(false);

LBLsimpan.setVisible(true);

Panel1.add(LBLsimpan);

BTNclear.setEnabled(false);

}

});

setVisible(true);

}

public static void main(String[] args){

DemoAction Demoaksi =new DemoAction();

} }

maka ketika program di Run akan menampilkan;

DEMO KEY;

Contoh program demo key;

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

public class DemoKey extends JFrame implements KeyListener{

    private String baris1="";

private JTextArea textArea;

public DemoKey(){

super("Mencoba Key Event");

textArea =new JTextArea (10,15);

textArea.setText("Tekan sembarang tombol di keyboard...");

textArea.setEnabled(false);

textArea.setDisabledTextColor(Color.BLACK);

getContentPane().add(textArea);

addKeyListener (this);

setSize (300,150);

setLocationRelativeTo(null);

setVisible(true);

}

public void keyPressed (KeyEvent e){

textArea.setText("Tombol yang ditekan : "+

e.getKeyText(e.getKeyCode()));

}

public void keyReleased (KeyEvent e){

textArea.setText("Tombol yang dilepas : "+

e.getKeyText(e.getKeyCode()));

}

public void keyTyped (KeyEvent e){

textArea.setText("Tombol yang ditulis : "+

e.getKeyChar());

}

public static void main (String args[]){

DemoKey test =new DemoKey();

test.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

}

maka ketika program di Run akan menampilkan;

DEMO ACTIONKEY;

contoh program demo ActionKey(gabungan);

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

public class DemoAction2  extends JFrame{

private String baris1="";

private JTextArea textArea; 

private JButton BTNsimpan =new JButton("simpan"),

BTNclear =new JButton("Clear");

private JLabel LBLsimpan =new JLabel("Jihan nabela"),

LBLclear =new JLabel("Data telah terhapus");

DemoAction2(){

super("Gabungan demo Action demo key");

textArea =new JTextArea (10,15);

textArea.setText("Silahkan masukkan nama anda....");

textArea.setEnabled(false);

textArea.setDisabledTextColor(Color.BLACK);

getContentPane().add(textArea);

setSize (300,150);

setLocationRelativeTo(null);

setVisible(true); 

JPanel Panel1 =new JPanel();

Panel1.setLayout(new FlowLayout());

Panel1.add(BTNsimpan);

Panel1.add(BTNclear);

getContentPane().add(Panel1);

setSize(200,150);

setDefaultCloseOperation(EXIT_ON_CLOSE);

BTNclear.addActionListener(new ActionListener(){

public void actionPerformed (ActionEvent evn){

BTNsimpan.setVisible(false);

BTNclear.setVisible(false);

LBLclear.setVisible(true);

Panel1.add(LBLclear);

BTNsimpan.setEnabled(false);

}

});

BTNsimpan.addActionListener(new ActionListener(){

public void actionPerformed (ActionEvent evn){

BTNsimpan.setVisible(false);

BTNclear.setVisible(false);

LBLsimpan.setVisible(true);

Panel1.add(LBLsimpan);

BTNclear.setEnabled(false);

}

});

setVisible(true);

}

public static void main(String[]args){

DemoAction2  Demoaksi =new DemoAction2();

}

}

maka jika program dirun akan menampilkan;
