Convert HASHSET to TREESET

import java.util.HashSet;
import java.util.TreeSet;
import java.util.Set;
class ConvertHashsettoTreeset{
  public static void main(String[] args) {
                                                                              // Create a HashSet
     HashSet<String> hset = new HashSet<String>();

     //add elements to HashSet
     hset.add("java");
     hset.add("DOTNET");
     hset.add("ORACLE");
     hset.add("MY SQL");

     // Displaying HashSet elements
     System.out.println("HashSet contains: "+ hset);

     // Creating a TreeSet of HashSet elements
     Set<String> tset = new TreeSet<String>(hset);

     // Displaying TreeSet elements
     System.out.println("TreeSet contains: ");
     for(String temp : tset){
        System.out.println(temp);
     }
  }
}



OUTPUT:

HashSet contains: [MY SQL, DOTNET, ORACLE, java]
TreeSet contains:
DOTNET
MY SQL
ORACLE

java
