Question

File Account.java (see 4.1. A Flexible Account Class exercise) contains a definition for a simple bank account class withmethods to withdraw, deposit, get the balance and account number, and return a String representation. Note that theconstructor for this class creates a random account number. Save this class to your directory and study it to see how it works.Now modify it to keep track of the total number of deposits and withdrawals (separately) for each day, and the total amountdeposited and withdrawn. Write code to do this as follows:

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 +

"\nAccount Number: " + acctNum +

"\nBalance: " + balance;

}

}

//************************************************************// TestAccount.java//// A simple driver to test the overloaded methods of// the Account class.//************************************************************
import java.util.Scanner;
public class TestAccount

{

public static void main(String[] args)

{

String name;

double balance;

long acctNum;

Account acct;
Scanner scan = new Scanner(System.in);
System.out.println("Enter account holder's first name");

name = scan.next();

acct = new Account(name);

System.out.println("Account for " + name + ":");

System.out.println(acct);
System.out.println("\nEnter initial balance");

balance = scan.nextDouble();

acct = new Account(balance,name);

System.out.println("Account for " + name + ":");

System.out.println(acct);

System.out.println("\nEnter account number");

acctNum = scan.nextLong();

acct = new Account(balance,name,acctNum);

System.out.println("Account for " + name + ":");

System.out.println(acct);
System.out.print("\nDepositing 100 into account, balance is now ");

acct.deposit(100);

System.out.println(acct.getBalance());

System.out.print("\nWithdrawing $25, balance is now ");

acct.withdraw(25);

System.out.println(acct.getBalance());

System.out.print("\nWithdrawing $25 with $2 fee, balance is now ");

acct.withdraw(25,2);

System.out.println(acct.getBalance());
System.out.println("\nBye!");

}

}

1. Add four private static variables to the Account class, one to keep track of each value above (number and total amount ofdeposits, number and total of withdrawals). Note that since these variables are static, all of the Account objects sharethem. This is in contrast to the instance variables that hold the balance, name, and account number; each Account has itsown copy of these. Recall that numeric static and instance variables are initialized to 0 by default.
2. Add public methods to return the values of each of the variables you just added, e.g., public static int getNumDeposits().3. Modify the withdraw and deposit methods to update the appropriate static variables at each withdrawal and deposit4. The Provided ProcessTransactions.java contains a program that creates and initializes two Account objects and enters a
loop that allows the user to enter transactions for either account until asking to quit. This loop contains the transactionsfor a single day. Embedded loop allows the transactions to be recorded and counted for many days. At the beginning ofeach day print the summary for each account, then have the user enter the transactions for the day. When all of thetransactions have been entered, print the total numbers and amounts (as above), then reset these values to 0 and repeatfor the next day. Run this test. No need to change this class.

Answer 1

Hi Friend, You have not mentioned about methos 'resetCounters', so i have implemented all required functionality except 'resetCounters' methos.

please let me know in case of any issue.
