Question

1. In this assignment you create a small project with a base class 'Account' which represents a generic account independent of whether the account is a Client or Vendor or Bank account. Then we will define a derived class 'BankAccount' class that represents the bank account. The BankAccount class is derived from the Account class, and extends the Account class functionality. The functionality of the BankAccount class is to handle deposits and withdrawals. You create a base class called Account and a derived class called BankAccount. You create two methods in BankAccount class: one for Deposit() and another one Withdraw() . See below for the Interface design.ghh
2. Your main form has eight label controls, two textbox controls and four buttons.
3. Customer Name and Account are static value.
4. You enter Starting Account Balance and Transaction Amount. Clicking on Deposit button adds the Transaction Amount to Starting Account Balance and displays in Account Balance label.
5. Clicking on Withdraw button checks to make sure there is sufficient fund in Starting Account Balance, if not it displays a message: The amount to withdraw exceeds account balance.

class Account{

static long balance=0;

}

class Bankaccount extends Account {

Scanner sc=new Scanner(System.in);

    balance=balance+amt;

  }

  void withdrawal()

  {

    long amount;

    System.out.println("Enter Amount U Want to withdraw : ");

    amount=sc.nextLong();

    if(balance>=amount)

    {

      balance=balance-amount;

    }

    }

  }

   Bankaccount b = new Bankaccount();

    int ch;

    do

    {

      System.out.println("Main Menu\n1.Balance\n2.Deposit\n3.Withdrawal\n4.Exit");

      ch=sc.nextInt();

      switch(ch)

      {

        case 1:

          b.Showbalance();

          break;

        case 2:

          b.deposit();

          break;

        case 3:

          b.withdrawal();

          break;

        case 4:

          System.out.println("Good Bye..");

          break;

      }

    }

    while(ch!=4);

  }
