Question

Write a test program (class named TestAccount) that does the following: • Creates 2 objects - a Saving Account and a Checking Account. Get user inputs for account information that is needed to create these 2 objects. • Get user input for an amount to be withdrawn from the Checking Account (for example, $2,500) and an amount to be deposited to the Checking Account (for example, $3,000). Make sure the overdraft restrictions work. • Similarly, withdraw and deposit from and into the Saving Account also. • Finally, print the account information for both the Checking and Saving accounts (i.e., print the current balance (after withdrawal and deposit), the monthly interest, and the date when these two accounts were created).

       Scanner scan = new Scanner(System.in);

       System.out.println("Account for " + name + ":");

       acctNum = scan.nextLong();
       acct = new Account(balance, name, acctNum);
       System.out.println("Account for " + name + ":");
       System.out.println(acct);

       System.out.print(" Depositing 100 into account, balance is now ");
       acct.deposit(100);
       System.out.println(acct.getBalance());
       System.out.print(" Withdrawing $2500, balance is now ");
       acct.withdraw(2500);
       System.out.println(acct.getBalance());
       System.out.print(" Withdrawing $25, balance is now ");
       acct.withdraw(25);
       System.out.println(acct.getBalance());

   }
}

OUTPUT:

Enter account holder's first name

Account Number: 0
Balance: 0.0

Enter initial balance

Account for Srinivas:
Name:Srinivas
Account Number: 3244
Balance: 234.0

Depositing 100 into account, balance is now 334.0

Withdrawing $2500, balance is now Insufficient funds
334.0

Withdrawing $25, balance is now 309.0
