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);

   }

}
