Instructions

Start Apache NetBeans.

Create a new project called YourlastnameLab$2$

Write the following program in the editor window making sure to use your name

instead of Bram Stoker:

package cscilo$11.$lab$2$;

import java.util.Scanner;

$\frac{?}{?}****$

CSCI $1011$ Lab $2$

@author Bram Stoker

A program that calculates interest on a deposit

$*/$

public class BramStokerLab$2\{$

$\frac{?}{?}****$

@param args the command line arguments

$*$ APSU

public static void main$($String$[]$ args$)\{$

Scanner keyboard $=$ new Scanner$($

System.in$)$;

System.out.println$("$Welcome to Bram Stoker's interest

calculator."$)$;

System.out.println$()$;

System.out.println$("$Please enter your initial deposit

amount:"$)$;

double balance $=$ keyboard.nextDouble$()$;

balance $=$ balance balance $**0\mathrm{.}049$;

System.out.println$("$With a $4\mathrm{.}9\%$ APR your deposit will be worth

Run the program and test it with sample input. Do this several times.

Modify the program so it uses a named constant in place of $0\mathrm{.}049.$

Run the program and test it to see if it gives the same values.

Modify the interest rate to $0\mathrm{.}059.$

Run the program again and test it to see the values it gives have changed.

Did you change the output, so it now says $5\mathrm{.}9\%?$ If not make that change and run the

program again.

Since it would be easier not to have to change the program in two places, declare a

new double variable called percent and set its value to $100$ times the interest rate.

Modify your output statement so it uses the percent variable instead of $5\mathrm{.}9.$

Run the program again and test it to make sure it still works properly.

Add some additional statements to compute what the balance will be after a second

year of earning interest and display this result along with the original result.

Run the program again and test it to make sure that the new code works.
