Description:

Below example shows how to copy content of LinkedHashSet elements to an array object.


Code:
package com.java2novice.linkedhashset;

import java.util.LinkedHashSet;

public class MyLhsToArrayEx {

	public static void main(String a[]){
		
		LinkedHashSet<String> lhs = new LinkedHashSet<String>();
		//add elements to LinkedHashSet
		lhs.add("first");
		lhs.add("second");
		lhs.add("third");
		System.out.println("LinkedHashSet content: ");
		System.out.println(lhs);
		String[] strArr = new String[lhs.size()];
		lhs.toArray(strArr);
		System.out.println("Copied array content:");
		for(String str:strArr){
			System.out.println(str);

	}
}

Output:
LinkedHashSet content:
