The account class contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. modify the file as follows: 1. overload the constructor as follows: a. public account (double initbal, string owner, long number) - initializes the balance, owner, and account number as specified. b. public account (double initbal, string owner) - initializes the balance and owner as specified; randomly generates the account number. c. public account (string owner) - initializes the owner as specified; sets the initial balance to 0 and randomly generates the account number.2. overload the withdraw method with one that also takes a fee and deducts that fee from the account.

I've updated the Account class as per the instructions. The instructions mention "the constructor for this class creates a random account number" although I didn't find where that was. As a result, I created a simple method to generates the account number (located at the bottom of the class). Be sure you understand the changes (highlighted in yellow) and feel free to ask follow-up questions:

Explanation:

//

// Account.java

//

// A bank account class with methods to deposit to, withdraw from,

// change the name on, and get a String representation

// of the account.

//

import java.util.Random;   // Used for Random # generator

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;

}

//

public Account(double initBal, String owner)

     {

        balance = initBal;

               name = owner;

            acctNum = generateAccountNumber();

       }

  //

 public Account(String owner)

     {

        balance = 0;

             name = owner;

            acctNum = generateAccountNumber();

       }

   //

 // 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;

               else

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

}

 //

   public void withdraw(double amount, double fee)

  {

        double amountWithFee = amount + fee;

               if (balance >= amountWithFee)

                 balance -= amountWithFee;

        else

                     System.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 +

          "\nAccount Number: " + acctNum +

         "\nBalance: " + balance;

 }

 //

//

// Returns a random account number between 10000 - 99999

 //

       private long generateAccountNumber()

     {

        Random r = new Random();        // Seed the random number genertor with the system time

         return 10000 + r.nextInt(89999);        // .nextInt(89999) will return a value between 0 and 89999)

      }

}

i just did so your welcome!
