With this example we are going to demonstrate how to convert a LinkedHashSet to an Object array. In short, to convert a LinkedHashSet to an Object array you should:
- Create a new LinkedHashSet.
- Populate the set with elements, using the
add(E e)API method of LinkedHashSet. - Invoke
toArray()method of LinkedHashSet, that returns an array containing all of the elements in this set. The method allocates a new array. The caller is thus free to modify the returned array. The length of the returned array is equal to the number of elements returned by the set iterator.
Let’s take a look at the code snippet that follows:
package com.javacodegeeks.snippets.core;
import java.util.LinkedHashSet;
public class LinkedHashSetToArray {
public static void main(String[] args) {
// Create a LinkedHashSet and populate it with elements
LinkedHashSet linkedHashSet = new LinkedHashSet();
linkedHashSet.add("element_1");
linkedHashSet.add("element_2");
linkedHashSet.add("element_3");
// Object[] toArray() method returns an array containing all of the elements in this set
Object[] objArray = linkedHashSet.toArray();
System.out.println("Elements in Array :");
for(int i=0; i < objArray.length ; i++)
System.out.println(objArray[i]);
}
}
Output:
Elements in Array :
element_1
element_2
element_3
This was an example of how to convert a LinkedHashSet to an Object array in Java.
