Create a HashSet

This example shows how to create a Set and add objects to it.
Unlike classes implementing the List interface, a Set class doesn't allow the same value to be stored twice.

import java.util.HashSet;
import java.util.Set;


public class HashSetExample {

/**
* Example method for using a Set
*/
public void hashSetExample() {

Set personType = new HashSet();


//Add the items to the Set
personType.add("student);
personType.add("employee);
personType.add("pensioner);
}
}
