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 object- oriented 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:
<Output>
Loan Amount: 10000 Number of Years: 5
| Interest | Rate | Monthly Payment | Total Payment |
| 5.000% | $188.71 | $11,322.74 | |
| 5.125% | $189.28 | $11,357.13 | |
| 5.250% | $189.85 | $11,391.59 | |
| … 7.875% | $202.17 | $12,129.97 | |
| 8.000% | $202.76 | $12,165.83 |
<End output>
Use the formulas below to compute monthly payment and total payment.
𝑚𝑜𝑛𝑡ℎ𝑙𝑦𝑃𝑎𝑦𝑚𝑒𝑛𝑡 = (𝑙𝑜𝑎𝑛𝐴𝑚𝑜𝑢𝑛𝑡 ∗ 𝑚𝑜𝑛𝑡ℎ𝑙𝑦𝐼𝑛𝑡𝑒𝑟𝑒𝑠𝑡𝑅𝑎𝑡𝑒)/1 – (1 / (1 + 𝑚𝑜𝑛𝑡ℎ𝑙𝑦𝐼𝑛𝑡𝑒𝑟𝑒𝑠𝑡𝑅𝑎𝑡𝑒)12∗𝑛𝑢𝑚𝑏𝑒𝑟𝑂𝑓𝑌𝑒𝑎𝑟𝑠)
𝑡𝑜𝑡𝑎𝑙𝑃𝑎𝑦𝑚𝑒𝑛𝑡 = 𝑚𝑜𝑛𝑡ℎ𝑙𝑦𝑃𝑎𝑦𝑚𝑒𝑛𝑡 ∗ 12 ∗ 𝑛𝑢𝑚𝑏𝑒𝑟𝑂𝑓𝑌𝑒𝑎𝑟𝑠
