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
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
