hii,

The Set interface provides methods for accessing the elements of a finite mathematicalset. Sets do notallow duplicate elements.

Hi,

Here is the example of Set Interface in Java.

import java.util.*;

public class  JavaSetExample
{
    public static void main(String[] args) 
    {
        System.out.println("Set Example in Java!");

        // Create HashSet Object
        Set set = new HashSet(); 
        // Add elements to the HashSet object
        set.add("Java"); 
        set.add("JSP"); 
        set.add("Servlet"); 
        set.add("EJB"); 
        set.add("JPA"); 
        set.add("JSF"); 
        //Iterate set
        Iterator it = set.iterator(); 
        while (it.hasNext()) { 
        //Get it
        String element = (String)it.next(); 
            System.out.println(element);
        } 

    }
}

Thanks
