Please code this lab in Java and also add explanation:

The atm$-$lab code creates the ATM, but the methods in the Bank and BankAccount

classes which actually do the banking functions are incomplete.

The lab class exercise is to complete the BankAccount.

There are four places in the code you need to change:

$-$ in the Bank class, the login method needs code to find a bank account,

given a username and password

$-$ in the BankAccount class, the three methods withdraw, deposit and balance

need code added to make them work properly.

Add any more functionality that is possbile with a bank account$/$statements$/$issuing checks etc.
