Thread: Java Programming help please

i am writing a program that would be used for ticket sales and their are 100 tickets and a person can only buy 4 at a time. i need my program to not go negative at the end and also i need to stop the user from entering a negative number here is the code please help!



import java.util.Scanner;

public class ticketmaster {

public static void main(String[] args) {


// Variable decoration uses strings , doubles and final doubles.

Scanner in = new Scanner(System.in);

int balanceTicket = 100;

int desiredTicketAmount = 0;

int buyers = 0;







while (balanceTicket > 0)

{

System.out.println("please enter the number of tickets wanted");

desiredTicketAmount = in.nextInt();


if ( desiredTicketAmount > 4 )

{
System.out.println( "please enter a number less than 4 ");

System.out.println();

}

else if ( desiredTicketAmount <= 4 )

{

buyers++;
balanceTicket = balanceTicket - desiredTicketAmount;





System.out.println (" the number of tickes left are : " + balanceTicket);

System.out.println();
