Copy all elements of Java LinkedHashSet to an Object Array

First, create a LinkedHashSet and add elements −

LinkedHashSet<String> l = new LinkedHashSet<String>();
l.add(new String("1"));
l.add(new String("2"));
l.add(new String("3"));
l.add(new String("4"));
l.add(new String("5"));
l.add(new String("6"));
l.add(new String("7"));

Now, copy it to an object array like this −

// copying
Object[] arr = l.toArray();

The following is an example to copy all elements of a LinkedHashSet to an object array −

Example

 Live Demo

import java.util.*;
public class Demo {
   public static void main(String[] args) {
      LinkedHashSet<String> l = new LinkedHashSet<String>();
      l.add(new String("1"));
      l.add(new String("2"));
      l.add(new String("3"));
      l.add(new String("4"));
      l.add(new String("5"));
      l.add(new String("6"));
      l.add(new String("7"));
      System.out.println("LinkedHashSet elements...");
      System.out.println(l);
      // copying
      Object[] arr = l.toArray();
      System.out.println("Object Array: ");
      for (Object res: arr){
         System.out.println(res);
      }
   }
}

Output

LinkedHashSet elements...
[1, 2, 3, 4, 5, 6, 7]
Object Array:
1
2
3
4
5
6
7
