TextField txtPanjang, txtLebar, txtHasil;

Button btnHitung;

Label lblPanjang, lblLebar, lblHasil;

double hasil;

public nomer3flowlayout(String title) {

super(title);

this.addWindowListener(new WindowAdapter() {

public void window(WindowEvent e) {

dispose();

System.exit(1);

}});

Panel panelWest   = new Panel();

Panel panelCenter = new Panel();

panelWest.setLayout(new GridLayout(4, 1));

panelWest.add(lblPanjang = new Label(“Panjang: “));

panelWest.add(lblLebar   = new Label(“Lebar: “));

panelWest.add(new Label());

panelCenter.add(txtHasil   = new TextField());

btnHitung.addActionListener(this);

add(panelWest, BorderLayout.WEST);

add(panelCenter, BorderLayout.CENTER);

setSize(300, 150);

setVisible(true);

}

public void actionPerformed(ActionEvent e) {

if (e.getSource().equals(btnHitung)) {

hasil = Double.parseDouble(txtPanjang.getText()) * Double.parseDouble(txtLebar.getText());

txtHasil.setText(“”+hasil);

}}

public static void main(String[] args) {

nomer3flowlayout frm = new nomer3flowlayout(“Luas Persegi Panjang”);

}}

Border Layout

public class nomer3borderlayout extends JFrame {

public nomer3borderlayout (String title) {

super(title);

Container contentPane = getContentPane();

contentPane.setLayout(new BorderLayout(2,2));

contentPane.add(BorderLayout.NORTH, new JButton(“Utara”));

contentPane.add(BorderLayout.SOUTH, new JButton(“Selatan”));

contentPane.add(BorderLayout.EAST, new JButton(“Timur”));

contentPane.add(BorderLayout.WEST, new JButton(“Barat”));

contentPane.add(BorderLayout.CENTER, new JButton(“Tengah”));

}

public static void main(String args[]) {

nomer3borderlayout frame = new nomer3borderlayout(“Arah Mata Angin”);

frame.setDefaultCloseOperation(EXIT_ON_CLOSE);

frame.setSize(500, 300);

frame.setVisible(true);

}}

1.     Menampilkan gambar

Source Code :

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

import java.io.*;

public class nomer4 extends JFrame{

String gambar[] ={“No picture”,”a.jpg”, “b.jpg”, “c.jpg”,  “bunga.gif”};

Icon icons[] = { new ImageIcon( gambar[0] ),new ImageIcon( gambar[1] ), new ImageIcon( gambar[2] ),new ImageIcon( gambar[3] ),new ImageIcon( gambar[4] ) };

JLabel label;

JComboBox rafles;

public static void main(String[] args){

nomer4 program = new nomer4();}

public nomer4(){

super(“Menampilkan Gambar”);

Container container = getContentPane();

container.setLayout(new  FlowLayout(FlowLayout.CENTER, 0, 0));

rafles = new JComboBox( gambar );

rafles.setForeground(Color.BLUE);

rafles.setMaximumRowCount(2);

rafles.addItemListener(

new ItemListener() {

public void itemStateChanged(ItemEvent event ){

if( event.getStateChange() ==ItemEvent.SELECTED)

label.setIcon( icons[ rafles.getSelectedIndex() ] );

}});

container.add(“North”,rafles);

label = new JLabel( icons[0] );

container.add( label );

getContentPane().setBackground( Color.WHITE);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setSize(500,400);

setLocation(100,50);

setVisible(true);

}}

Memberi warna

Source Code :

package pendahuluan8;

import java.awt.*;

public class nomer4ke2 extends Frame {

Button merah= new Button(“Tombol merah”);

Button hijau= new Button(“Tombol hijau”);

Button biru= new Button(“Tombol biru”);

public nomer4ke2(){

this.setLayout(new FlowLayout());

this.add(merah, null);

this.add(hijau, null);

this.add(biru, null);

merah.setBackground(Color.red);

hijau.setBackground(Color.green);

biru.setBackground(Color.blue);

}

public static void main(String args []){

nomer4ke2 tombol=new nomer4ke2();

tombol.pack();

tombol.setTitle(“Tombol Coba AWT”);

tombol.setVisible(true);
