How do I check if a input (integer) matches another value (integer) that exits within my array?

hope this fix your issue As you see it's not possible to just write while(value != values[]) but you can search a value in an array or check if the value is contained in a List:
--- First way
import java.util.Scanner;
import java.util.List;
import java.util.ArrayList;

public class InArrayWithAsListContains {

    public static void main(String[] args)
    {
        Scanner input = new Scanner(System.in);
        int value=0;
        List<Integer> values = new ArrayList<Integer>();

        values.add(16);
        values.add(10);
        values.add(11);
        values.add(14);
        values.add(17);    

        do {
            System.out.println("Enter a number:");
            value = input.nextInt();    
        } while(!values.contains(value)); 
    }
}
int[] arr = new int[] {16,10,11,14,17};        

// int[] into List<Integer> conversion
for (int i : arr) values.add(i);
import java.util.Scanner;
import java.util.Arrays;

public class Program {

    public static void main(String[] args)
    {
        Scanner input = new Scanner(System.in);
        int value=0;
        int[] values = {16,10,11,14,17};

        Arrays.sort(values);

        do {
            System.out.println("Enter a number:");
            value = input.nextInt();    
        } while(Arrays.binarySearch(values, value) < 0); 
    }
}

Java8 check if a given integer is present in Integer[] array

will be helpful for those in need You currently have an Integer[] therefore you can utilise Stream.of instead of IntStream.of.
IntStream.of only takes primitive integers whereas Stream.of is used for reference types.
boolean isPresent = Stream.of(nums).anyMatch(num -> Objects.equals(num, inputNum));
boolean isPresent = Arrays.stream(nums).anyMatch(num -> Objects.equals(num, inputNum));
