File Account.java contains a definition for a simple bank account class with methods to withdraw, deposit, get the balanceand account number, and return a String representation. Note that the constructor for this class creates a random accountnumber. Save this class to your directory and study it to see how it works. Then modify it as follows: 1. Overload the constructor as follows: public Account (double initBal, String owner, long number) - initializes the balance, owner, and account

number as specified public Account (double initBal, String owner) - initializes the balance and owner as specified; randomlygenerates the account number. public Account (String owner) - initializes the owner as specified; sets the initial balance to 0 and randomlygenerates the account number.

2. Overload the withdraw method with one that also takes a fee and deducts that fee from the account. File TestAccount.java contains a simple program that exercises these methods. Save it to your directory, study it to see whatit does, and use it to test your modified Account class.

public class Account

private double balance;

private String name;

private long acctNum; //-------------------------------------------------//Constructor -- initializes balance, owner, and account number//-------------------------------------------------

public Account(double initBal, String owner, long number)

{

balance = initBal;

name = owner;

acctNum = number;

} //-------------------------------------------------// Checks to see if balance is sufficient for withdrawal.// If so, decrements balance by amount; if not, prints message.//-------------------------------------------------

public void withdraw(double amount)

{

if (balance >= amount)

balance -= amount;

elseSystem.out.println("Insufficient funds");

}

//-------------------------------------------------// Adds deposit amount to balance.//------------------------------------------------- public void deposit(double amount){balance += amount;

} //-------------------------------------------------// Returns balance.//-------------------------------------------------

public double getBalance()

{

return balance;

} //-------------------------------------------------// Returns a string containing the name, account number, and balance.//-------------------------------------------------

public String toString()

{

return "Name:" + name +

" Account Number: " + acctNum +

" Balance: " + balance;

}

}
