Lab 4: Bank Account

• Review the dice simulation example files Die.java and DieTest.java. and other examples.
  
• In a file named BankAccount.java, create a class named BankAccount to simulate a bank account.
  • The bank balance should be stored in a private floating point variable named balance.
    
  • The BankAccount class should have the following methods:
  • withdraw() and deposit() should accept a single parameter which will decrease or increase the balance.
    For this assignment they should not have a return value, so their type should be void.
    
  • A constructor method BankAccount() should have an initial deposit parameter to initialise the account.
    
• In a file named BankAccountTest.java, create a class named BankAccountTest with just one method named main().
  • Ask the user to enter an initial deposit.
  • Create a new account object of type BankAccount with this initial deposit.
    
  • Loop through the following until the user enters 0:
    
  • Ask the user to enter a positive number for deposit, negative number for withdrawal, or 0 to exit.
  • After each deposit or withdrawal, print the current balance.
    
• Check: Make sure all your variables, methods and classes are either public or private as appropriate.
• Compile the programs by typing javac BankAccount.java BankAccountTest.java
  • If there are no other Java files in the current directory you can simply type javac *.java
• Run, test, debug and document the programs.
• Note: it is possible that the account balance will become negative. You may want to consider ways to prevent this.
  
• Send the source code to the instructor as two attachments in a message with subject java lab4.
