Question

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.

Answer 1

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 \\Enter 2 for Withdraw\\Enter 3 for Balance Enquiry\\0 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);

}

}
