Java Collection, TreeSet Exercises: Exercise-6 with Solution

Write a Java program to clone a tree set list to another tree set.

Sample Solution:

Java Code:

import java.util.TreeSet;
import java.util.Iterator;

  public class Exercise6 {
  public static void main(String[] args) {
    // create an empty tree set
     TreeSet<String> t_set = new TreeSet<String>();
   // use add() method to add values in the tree set
          t_set.add("Red");
          t_set.add("Green");
          t_set.add("Black");
          t_set.add("Pink");
          t_set.add("orange");
     
   System.out.println("Original tree set:" + t_set);  
    TreeSet<String> new_t_set = (TreeSet<String>)t_set.clone();
          System.out.println("Cloned tree list: " + t_set);      
     }
 }
