Amount deposited: 80000.00
Years: 15
Interest rate: 7.75

Hint: to solve this problem, compute 80000.00 (1 + 7.75 / 100)15

program should contain 4 rows by 2 columns of GUI components. They should be JLabels for displaying information and JTextFields for accepting input data from the user. Labels on the left column should be right-aligned; the result on the right column should be left-aligned

Explanation / Answer

mport java.awt.*;

import javax.swing.*;

import java.awt.event.*;

class TotalAmount extends JFrame

{

TotalAmount(){

JLabel lab1=new JLabel("Amount");

final JTextField text1=new JTextField(20);

JLabel lab2=new JLabel("Rate of Interest");

final JTextField text2= new JTextField(20);

JLabel lab3=new JLabel("Time");

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());

double t=Double.parseDouble(text3.getText());

double v1=r/100;

double v2=1+v1;

double v3=Math.pow(v2,t);

double amount=p*v3;

JOptionPane.showMessageDialog(null, "Total Amount is: "+amount);

}

});

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(10,70,100,20);

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 TotalAmount();

}

}
