SENG1110/6110 Programming Assignment 1 – Semester 2, 2018
GOODMATES LOAN INSTITUTION - Help to start
This document aims to give some initial steps to help you to start the assignment 1. Note that you do not need to follow
exactly these steps in the same order. In addition, the suggestions in each step are just one of the several options that you
have to implement the assignment. Note as well that these are just a starting point. Each time that you implement a new
method, test it before proceeding. It will save you time.
Step 1.
Write the first version of Account.java (there is a template already available to you in Blackboard)
From the assignment specification, declare the instance variables. Compile.
Implement a couple of the methods. You can start with setMonths() and getMonths(), for example. Compile.
Step2.
Write the first version of Client.java (there is a template already available to you in Blackboard).
From the assignment specification, declare the instance variables. Compile.
Implement a couple of the methods. You can start with setName() and getName(), for example. Compile.
Step3.
Write the first version of LoanCalculator.java (there is a template already available to you in Blackboard).
Let’s first write some statements to test the class Client.
Write the following statements in the method run() in LoanCalculator.java (some of them are already written in the
template):
Scanner console = new Scanner(System.in);
Client client = new Client();
String name;
System.out.print("name? ");
Client.setName(name);
System.out.println("name = "+client.getName());
Compile and run. If it works, then implement the next set/get methods in Client and try the same test.
After testing, delete these lines (they were used just for testing your Client class).
When you finish the implementation of all get/set methods in Client, then go to the next step.
Step5.
Let’s first write some statements in LoanCalculator.java to test the class Account.
Write the following statements in the method run() in LoanCalculator.java (some of them are already written in the
template):
Scanner console = new Scanner(System.in);
Account accountTest = new Account();
int months;
System.out.print("months? ");
accountTest.setMonths(months);
System.out.println("months = "+ accountTest.getMonths());
Compile and run. If it works, then implement the next methods in Account and try the same test.
After testing, delete these lines (they were used just for testing your Account class).
When you finish the implementation of all get/set methods in Account, then go to the next step.
Step 7.
Write the initial statements to ask and receive inputs from the user (name, age, income, amount, numberOfMonths,
typeOfAccount). Remember to check if the input numbers are positive. If they are negative, you should ask the input again.
Now you can instantiate the object client with these inputs. There are different ways to do this. Ask help if you are not sure
how to do it.http://www.5daixie.com/contents/9/1627.html
Step8.
Now go to the assignment instructions and implement each functionality. Remember to implement each one, compile, test
and when it is all working, go to the next one.
As said above, these steps are just the starting point. Depending on the questions from students, I will add more information
in Blackboard and send an email to all to let you know. Remember to use the discussion board to post your questions, but DO
NOT post your code.
