This example will shows us how to check the existence of the element in the LinkedHashSet. 

To check the existence of particular element in the LinkedHashSet we use  contain() . it check the availability of element in the Set.




 
public boolean contains(Object o) 
will return the answer in boolean value i.e. true/false

Simply calls the contain() along with the object of LinkedHashSet and pass it to blnExists object.

 

/**

package Example;
import java.util.LinkedHashSet;
import java .util.Iterator;

/**

public class ExistenceElements {




/**
* @param args
*/
public static void main(String[] args) {
LinkedHashSet Lhst = new LinkedHashSet();
Lhst.add("10");
Lhst.add("11");
Lhst.add("12");
Lhst.add("13");
Lhst.add("14");
Lhst.add("15");
Lhst.add("16");

System.out.println(" The LinkedHashSet contains the elements :"+Lhst);
Lhst.size();
System.out.println(" The size of the LinkedHashSet is:" + Lhst.size());
boolean blnExists=Lhst.contains("15");
System.out.println("The element is exists in the set is :"+blnExists);

// TODO Auto-generated method stub


}

}

The LinkedHashSet contains the elements :[10, 11, 12, 13, 14, 15, 16]
 The size of the LinkedHashSet is:7
The element is exists in the set is :true
