(JAVA) So my question is, "Write an application that inputs five numbers, each between 10 and 100, inclusive. As each number is read, display it only if its not a duplicate of a number already read. Provide for the worst case, in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values input after the user enters each new value." I've seen this question answered with a one-dimensional array, however, if possible, I'd like to try and use an ArrayList to complete this problem. Here is my ((incomplete)) code so far. I am entirely stuck on where to go next. Any help would be greatly appreciated.

import java.util.Scanner; import java.util.ArrayList; public class DisplayUniqueValueInput { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // creating an ArrayList from user input ArrayList userInputs = new ArrayList(5); // prompt user and store input while (true) { System.out.print("Enter an integer between 10 and 100:"); userInputs.add(scanner.nextInt()); // if user input is in the ArrayList if (userInputs >= 10 || userInputs <= 100) { boolean ifExists = false; for(userInputs : Integer) { if (userInputs.contains(Integer)) { ifExists = true; break; } } } } }
