ArrayList Without Duplicate java

Hi this is a  sample example of java how we can write a ArrayList and eliminate duplicates in it .Below is the code snippet that gives you an idea on how to eliminate duplicates from arraylist

import java.util.ArrayList;
public class ArrayListWithoutDuplicates {
     
 public static void main(String args[]){

  ArrayList<String> original = new ArrayList<String>();
  ArrayList<String> eliminateDuplicate= new ArrayList<String>();

  original.add("Naveen");
  original.add("Rajesh");
  original.add("Pradeep");
  original.add("Rajesh");


  for (String dupWord : original) {
      if (!eliminateDuplicate.contains(dupWord)) {
          eliminateDuplicate.add(dupWord);
      }
  }
  System.out.println(eliminateDuplicate);
 }

}

Output : [Naveen, Rajesh, Pradeep]
