MITS4002 Activity 07

This assessment item relates to the unit learning outcomes as in the unit descriptors.
This checks your understanding about object-oriented software development.
This assessment covers the following LOs.
LO1 Demonstrate understanding of classes, constructors, objects, data types and
instantiation; Convert data types using wrapper methods and objects
LO2 Independently analyse customer requirements and design object-oriented programs
using scope, inheritance, and other design techniques; Create classes and objects that
access variables and modifier keywords. Develop methods using parameters and return
values
LO3 Demonstrate adaptability in building control and loop structures in an objectoriented environment; Demonstrate use of user defined data structures and array
manipulation

Project: Comparing Loans
Problem Description:
Write a program that lets the user enter the loan amount and loan period in number of
years and displays the monthly and total payments for each interest rate starting from 5%
to 8%, with an increment of 1/8. Here is a sample run:

Loan Amount: 10000
Number of Years: 5
Interest Rate
5.000%
5.125%
5.250%
...
7.875%
8.000%

Monthly Payment
$188.71
$189.28
$189.85
$202.17
$202.76

Total Payment
$11,322.74
$11,357.13
$11,391.59
$12,129.97
$12,165.83


Use the formulas below to compute monthly payment and total payment.

Design: (Describe the major steps for solving the problem.)

Coding: (Copy and Paste Source Code here. Format your code using Courier 10pts)

Output screenshot: (Paste your output screenshot here)

Testing: (Describe how you test this program)

Submit the following items:

1. This Word document and Submit to Moodle (you must submit the program regardless
whether it complete or incomplete, correct or incorrect)
Hint:
1. Can you get the first four rows manually? This will help you understand
how to compute the numbers mathematically.
2. Can you write a program to produce the first four rows? This will help you
see the pattern.
3. Can you generalize it in a loop to produce all the rows?
4. Finally, format the output correctly.
