PROGRAM TO PRINT ALL DISTINCT ELEMENTS OF A GIVEN INTEGER ARRAY



import java.util.*;
  
class Main
{
    // This function prints all distinct elements
    static void printDistinct(int arr[])
    {
        // Creates an empty hashset
        HashSet<Integer> set = new HashSet<>();
  
        // Traverse the input array
        for (int i=0; i<arr.length; i++)
        {
           // If not present, then put it in hashtable and print it
            if (!set.contains(arr[i]))
            {
                set.add(arr[i]);
                System.out.print(arr[i] + " ");
            }
        }
    }
  
    // Driver method to test above method
    public static void main (String[] args)
