My code breaks when the user is supposed to input a unique number for itemNumber, however there is no error displayed in NetBeans, can someone help me with why this happens?
package pre_release;
import java.util.*;
public class Pre_Release {
public static void main(String[] args) {
int numberOfItems = 0;
int number;
int bidNumber;
double highestBid = 0;
Scanner userInput = new Scanner (System.in);
Scanner userString = new Scanner (System.in);
Scanner userDouble = new Scanner (System.in);
Scanner userBuyer = new Scanner (System.in);
Scanner userInt = new Scanner (System.in);
Scanner userItem = new Scanner (System.in);
do{
System.out.println("Please enter the the amount of items for the auction. Needs to be more than or equal to 10");
numberOfItems = userInput.nextInt();
} while(numberOfItems<10);
String[] description = new String[numberOfItems];
double[] reservePrice = new double[numberOfItems];
double[] bid = new double[numberOfItems];
int[] itemNumber;
itemNumber = null;
int[] buyNumber = new int[numberOfItems];
for(int count=0;count<numberOfItems;count++){
System.out.println("Input a number for each item number");
itemNumber[count] = userInt.nextInt();
}
for(int count=0;count<numberOfItems;count++){
bidNumber=0;
System.out.println("Please give your item a reserved price");
reservePrice[count] = userDouble.nextDouble();
System.out.println("Please describe your item");
description[count] = userString.nextLine();
}
System.out.println("Please enter the desired item you wish to see");
number = userInt.nextInt();
for(int count2=0;count2<numberOfItems;count2++){
if(itemNumber[count2] == number){
System.out.println("The reserved price is" + reservePrice[numberOfItems]);
System.out.println(description[numberOfItems]);
}
System.out.println("Would you like to put a bid on this item? Needs to be more than" + reservePrice[numberOfItems]);
}
}
}
