Program: Basic LinkedHashSet Operations.

Below example shows how to create LinkedHashSet object, adding elements to it, getting size of LinkedHashSet object, and is the set empty or not.

package com.java2novice.linkedhashset;

import java.util.LinkedHashSet;

public class MyLkdHashSetOperations {

	public static void main(String a[]){
		
		LinkedHashSet<String> lhs = new LinkedHashSet<String>();
		//add elements to HashSet
		lhs.add("first");
		lhs.add("second");
		lhs.add("third");
		System.out.println(lhs);
		System.out.println("LinkedHashSet size: "+lhs.size());
		System.out.println("Is LinkedHashSet emplty? : "+lhs.isEmpty());
	}
}

[first, second, third]
LinkedHashSet size: 3
Is LinkedHashSet emplty? : false
