1. Write statements that perform the following one‐dimensional‐array operations:
2. Create a class Account with the following data members: balance, accountHolder. Create two objects with different states. Create a driver class BankAccounts with the main method to create the objects of the Account class. 3. Modify the class Account to provide a method called debit that withdraws money from an Account. Ensure that the debit amount does not exceed the Account’s balance. If it does, the balance should be left unchanged and the method should print a message indicating ―Debit amount exceeded account balance. Modify class BankAccounts to test method debit. 4. Modify the class Account to provide a method called credit that deposits money into an Account. Modify class BankAccounts to test method credit. |

Modify the class Account to provide a method called debit that withdraws money from an Account. Ensure that the debit amount does not exceed the Account’s balance. If it does, the balance should be left unchanged and the method should print a message indicating ―Debit amount exceeded account balance.
Modify class BankAccounts to test method debit.
Modify the class Account to provide a method called credit that deposits money into an Account.
Modify class BankAccounts to test method credit.
