program
. Develop a program that accepts an initial amount of money (called the principal), a simple annual interest rate, and a number of months will compute the balance at the end of that time. Assume that no additional deposits or withdrawals are made and that a month is 1/12 of a year. Total interest is the product of the principal, the annual interest rate expressed as a decimal, and the number of years.

Hi Friend,
Try the following code:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
class TotalInterest extends JFrame
{
TotalInterest(){
JLabel lab1=new JLabel("Principal");
final JTextField text1=new JTextField(20);
JLabel lab2=new JLabel("Rate of Interest");
final JTextField text2= new JTextField(20);
JLabel lab3=new JLabel("Number of Months");
final JTextField text3=new JTextField(20);
JButton b=new JButton("Get");
b.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
double p=Double.parseDouble(text1.getText());
double r=Double.parseDouble(text2.getText())/100;
double t=Double.parseDouble(text3.getText())/12;
double interest=p*r*t;
JOptionPane.showMessageDialog(null, "Total Interest is: "+interest);
}
});
setLayout(null);
lab1.setBounds(10,10,100,20);
text1.setBounds(150,10,200,20);
lab2.setBounds(10,40,100,20);
text2.setBounds(150,40,200,20);
lab3.setBounds(10,70,120,20);
text3.setBounds(150,70,200,20);
b.setBounds(150,110,70,20);
add(lab1);
add(text1);
add(lab2);
add(text2);
add(lab3);
add(text3);
add(b);
setVisible(true);
setSize(400,200);
}
public static void main(String[] args)
{
new TotalInterest();
}
}
Thanks
