CSC139 Chapter 9 Lab Assignments (1) Classes and Objects Objectives In this lab assignment, students will learn: - How to design and define class - How to create object - How to define a tester program to test the object Goals In this lab assignment, students will demonstrate the abilities to: - Design and define class - Create object - Define a tester program to test the object Grading - Design and create a GUI (20 pts) - Design and define class (40 pts) - Define tester program (40 pts) Develop a " BankAccount " windows form project, which will allow user to - Enter amount of money to deposit, withdraw or move - Deposit money in checking or savings account. - Withdraw money from checking or savings account. - Move money between checking account and saving account. - View the new balance on the form after each transaction. Here is sample input/output: When start to run project, initial balances for both checking and saving accounts ($1000.00) should be displayed on the form. After deposit $500.00 to checking account. After move $800.00 from saving to checking account. If user attempts to withdraw $4000.00 from checking account at this moment, a MessageBox should be displayed with an error message. Project specifications -------- 1. This project should perform object-oriented programming. Add a class file "Account.vb" to define class "Account", rename "Form1.vb" file as "AccountTesterForm.vb" which will create account object and test the object’s attributes and behaviors. 2. This is the GUI for the bank. The amount of money need to be entered from the textbox, each button represents a type of transaction. The new balance will be displayed on the form after each transaction. Please use the same control names in order to use the tester program code below. balanceLabel amountTextBox moveStoCButton withdrawSavingButton depositSavingButton moveCtoSButton depositCheckingButton withdrawCheckingButton 3. Here is the definition of class Account, some codes are missing, you may copy the code to your project in Visual Studio and complete the missing code. Public Class Account Private savingBalance As Decimal 'instance variable for balance in saving account Private checkingBalance As Decimal 'instance variable for balance in checking account 'constructor which initialize balances in both accounts to 1000.00 Public Sub New() savingBalance = 1000.0 checkingBalance = 1000.0 End Sub 'property for savingBalance Public Property Saving() As Double Get Return savingBalance End Get Set(ByVal value As Double) If value < 0 Then savingBalance = 0 Else savingBalance = value End If End Set End Property 'property for checkingBalance Public Property Checking() As Double 'write your code here End Property 'define how to deposit money to checking a.
