Assignment Activity 1:
Project: Comparing loans with various interest rates
Problem Description:
Rewrite Exercise 5.21 to create a user interface, as shown in the following figure. Your program should let the user enter the loan amount and loan period in number of years from a text field and should display the monthly and total payments for each interest rate starting from 1percent to 8 percent, with increments of one-eighth, in a text area.
Design: (Maw a sketch of UI)
Coding: (Paste your code here)
Screen shots:
Submit the following items:
1. Submit this Word document to Moodie (you must submit the program regardless whether it complete or incomplete, correct or incorrect)
2. Fill in self-evaluation:
- Is the Ul created correctly?
- Are the values computed correctly?
- Is the table displayed correctly?
Assignment Activity 2:
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:

Use the formulas below to compute monthly payment and total payment.
Analysis: (Describe the problem including input and output in your own words.)
Design: (Describe the major steps for solving the problem.) Coding: (Copy and Paste Source Code here. Format your code using Courier lOpts)
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 Moodie (you must submit the program regardless whether it complete or incomplete, correct or incorrect)
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.
