Java program for a set operation

Set Operation in java

In this program, we will write a program for set operations in java.

The set is an interface that 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 of Set Operations in Java:

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

Set Operations Examples

// Java code for adding elements in Set 
importjava.util.*; 
publicclassSet_example
{ 
    publicstaticvoidmain(String[] args) 
    { 
        // Set deonstration using HashSet
        Set<String>hash_Set = newHashSet<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 = newTreeSet<String>(hash_Set); 
        System.out.println(tree_Set); 
    } 
}
