Write a Java program to add all the elements of a specified tree set to another tree set.

Sample Solution:

Java Code:

import java.util.TreeSet;
public class Exercise3 {
  public static void main(String[] args) {
  TreeSet<String> tree_set1 = new TreeSet<String>();
  tree_set1.add("Red");
  tree_set1.add("Green");
  tree_set1.add("Orange");
  System.out.println("Tree set1: "+tree_set1);
  TreeSet<String> tree_set2 = new TreeSet<String>();
  tree_set2.add("Pink");
  tree_set2.add("White");
  tree_set2.add("Black");
  System.out.println("Tree set2: "+tree_set2);
   // adding treetwo to treeone
   tree_set1.addAll(tree_set2);
   System.out.println("Tree set1: "+tree_set1);
 }
}

Sample Output:

Tree set1: [Green, Orange, Red]                                        
Tree set2: [Black, Pink, White]                                        
Tree set1: [Black, Green, Orange, Pink, Red, White]
