java program for set operation

**Aim**: Write a java program for set operation

The set is an interface which extends Collection. It is an unordered collection of objects in which duplicate values cannot be stored. Basically, Set is implemented by Hash Set, LinkedHashSet or TreeSet (sorted representation). Set has various methods to add, remove clear, size, etc to enhance the usage of this interface

*Procedure for Set Operations in Java:*

**Set**is an interface which extends**Collection**. It is an unordered**collection**of objects in which duplicate values cannot be stored.- Basically,
**Set**is implemented by HashSet, LinkedHashSet or TreeSet (sorted representation). **Set**has various methods to add, remove clear, size, etc to enhance the usage of this interface.

**Program:**

// Java code for adding elements in Set

**import**java.util.*;

**publicclass**Set_example

{

**publicstaticvoid**main(String[] args)

{

// Set deonstration using HashSet

Set<String>hash_Set = **new**HashSet<String>();

hash_Set.add(“Hello”);

hash_Set.add(“For”);

hash_Set.add(“Hello”);

hash_Set.add(“Example”);

hash_Set.add(“Set”);

System.out.print(“Set output without the duplicates”);

System.out.println(hash_Set);

// Set deonstration using TreeSet

System.out.print(“Sorted Set after passing into TreeSet”);

Set<String>tree_Set = **new**TreeSet<String>(hash_Set);

System.out.println(tree_Set);

}

}
