Rumus Gaya dengan Java

Tugas 2 java terdiri atas 2 file

1. file internal

yang berisi :

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

public class internal extends JInternalFrame{

//private JInternalFrame saya = new JInternalFrame ();

private JLabel label1 = new JLabel("massa (m) ="),

label2 = new JLabel("percepatan (a)="),

label3 = new JLabel("gaya (F) =");

private JTextField txt1 = new JTextField(),

txt2 = new JTextField(),

txt3 = new JTextField();

private JLabel gambar = new JLabel (new ImageIcon("adhi2.jpg"));

private JButton btnCari = new JButton("hitung");

public internal(){

super("GAYA",false,true,true,true);

getContentPane().setLayout(null);

label1.setBounds(30,20,100,20);

label2.setBounds(30,60,100,20);

label3.setBounds(30,100,100,20);

gambar.setBounds(0,0,250,250);

txt1.setBounds(130,20,100,20);

txt2.setBounds(130,60,100,20);

txt3.setBounds(130,100,100,20);

btnCari.setBounds(130,140,100,20);

getContentPane().add(label1);

getContentPane().add(label2);

getContentPane().add(label3);

getContentPane().add(txt1);

getContentPane().add(txt2);

getContentPane().add(txt3);

getContentPane().add(btnCari);

getContentPane().add(gambar);

btnCari.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent e){

int Hasil = Integer.parseInt(txt1.getText()) * Integer.parseInt(txt2.getText());

txt3.setText(Integer.toString(Hasil));

}

});

setVisible(true);

setSize(280,280);

}

}

untuk file ke dua ber judul RmsAdhi

yang isi nya :

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

public class RmsAdhi{

viewzoomin= new JMenuItem ("zoom in ");

private JToolBar tool = new JToolBar ();

private JButton btnnew = new JButton (new ImageIcon("adhie.jpg"));

//private JLabel gambar = new JLabel (new ImageIcon("g.jpg"));

public RmsAdhi (){

file.add(filenew);

adhi.setJMenuBar(cahya);

ActionListener mulai = new ActionListener(){

public void actionPerformed(ActionEvent e){

baru.add(x);

x.setVisible(true);

}

};

btnnew.addActionListener(mulai);

tool.add(btnnew);

baru.setBackground(Color.blue);

adhi.getContentPane().add(tool, BorderLayout.NORTH);

adhi.getContentPane().add(baru, BorderLayout.CENTER);

//afdal.getContentPane().add(gambar);

adhi.setVisible(true);

adhi.setSize (800,500);

adhi.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

public static void main (String[] args ){

new RmsAdhi ();
