Question

***\\\\I have been trying to run this but I think there is something wrong with the variables not being saved properly. I really appreciate some help.
***

class Main {
public static void main(String[] args) {
final int NUM_ITEMS = 2;
ItemToPurchase[] itemList = new ItemToPurchase[NUM_ITEMS];
  
clearScreen();
  
promptItem(itemList);
total(itemList);
}

  
public static void promptItem(ItemToPurchase[] itemList)
{
Scanner scnr = new Scanner(System.in);
  
String tempItem;
int tempPrice;
int tempQuantity;
  
int count;
//-----Print prompts by number of items------//
for(count = 0; count < itemList.length; ++count)
{
System.out.println("Item " + (count + 1));
System.out.println("What is the item called?");
tempItem = scnr.next();
itemList[count].setName(tempItem);
  
System.out.println("How much does the item cost?\n$");
tempPrice = scnr.nextInt();
itemList[count].setPrice(tempPrice);
  
System.out.println("How many are you buying?");
tempQuantity = scnr.nextInt();
itemList[count].setQuantity(tempQuantity);
  
System.out.println("\n");
  
scnr.close();
}
}

ItemToPurchase.java

class ItemToPurchase {

private String tempItem;

private int tempPrice;

private int tempQuantity;

public ItemToPurchase() {

this.tempItem = " ";

this.tempPrice = 0;

this.tempQuantity=0;

}

public void setName(String tempItem) { this.tempItem = tempItem; }

public void setPrice(int tempPrice) { this.tempPrice = tempPrice; }

public void setQuantity(int tempQuantity) { this.tempQuantity = tempQuantity; }

}

Main.java

import java.util.*;

class Main {

public static void main(String[] args) {

final int NUM_ITEMS = 2;

ItemToPurchase[] itemList = new ItemToPurchase[NUM_ITEMS];

itemList[0]=new ItemToPurchase();

itemList[1]=new ItemToPurchase();

promptItem(itemList);

}

public static void promptItem(ItemToPurchase[] itemList)

{

Scanner scnr = new Scanner(System.in);

String tempItem;

int tempPrice;

int tempQuantity;

int count;

//-----Print prompts by number of items------//

for(count = 0; count < itemList.length; ++count)

{

System.out.println("Item " + (count + 1));

System.out.println("What is the item called?");

tempItem = scnr.next();

itemList[count].setName(tempItem);

System.out.println("How much does the item cost?\n$");

tempPrice = scnr.nextInt();

itemList[count].setPrice(tempPrice);

System.out.println("How many are you buying?");

tempQuantity = scnr.nextInt();

itemList[count].setQuantity(tempQuantity);

System.out.println("\n");

}

scnr.close();

}

}
