1) Your program must contain functions to: deposit, withdraw, balance inquiry and quit. 2) Based on the selection made by the user the functions must be called with the following criteria: a. A user can deposit any amount of money in their account. The function must display the new balance after depositing. by. A person can withdraw an amount as long as it is lower than or equal to his current balance. The function must also display a warning if the new balance is below $100. Must not allow the user to withdraw if amount is great than current balance. Before this function ends - the new balance must be displayed. c. Balance inquiry function must display the balance.

import java. util. Scanner;

public class num6 {

static double balance = 10000.5; / /Current Balance

//The main Method

public static void main (String[] args) {

//Request User Input

System. out. println ("Enter 1 for deposit / nEnter 2 for Withdraw/nEnter 3 for Balance Enquiry/n0 to quit ");

Scanner in = new Scanner (System. in);

int op = in. nextInt ();

//Check to determine the Operation the user wants

if (op = = 1) {

System. out. println ("Enter amount to deposit");

double depositeAmount = in. nextDouble ();

deposit (depositeAmount); / /Call the deposit method

}

if (op = = 2) {

System. out. println ("Enter amount to Withdraw");

double withdrawAmount = in. nextDouble ();

//validate the withdraw amount

if (withdrawAmount > balance) {

System. out. println ("Insuffucient fund");

System. out. println ("Your current balance is "+balance);

}

else {

withdraw (withdrawAmount); //Call withdraw Method

}

}

if (op = = 3) {

balanceEnquiry ();

}

}

//Deposit Method

public static double deposit (double depositAmount) {

double newBalance = balance + depositAmount;

System. out. println ("You deposited "+depositAmount+"Your new balance is "+newBalance);

return newBalance;

}

//Withdraw Method

public static double withdraw (double withdrawAmount) {

double newBalance = balance - withdrawAmount;

System. out. println ("You Withdrew "+withdrawAmount+"Your new balance is "+newBalance);

if (newBalance < 100) {

System. out. println ("Your Balance is low");

}

return newBalance;

}

//Balance Enquiry Method

public static void balanceEnquiry () {

System. out. println ("Your current balance is "+balance);

}

}
