Java: Iterate through all elements in a tree set

Java Collection, TreeSet Exercises: Exercise-2 with Solution

Write a Java program to iterate through all elements in a tree set.

Sample Solution:

Java Code:

import java.util.TreeSet;
public class Exercise2 {
  public static void main(String[] args) {
  TreeSet<String> tree_set = new TreeSet<String>();
  tree_set.add("Red");
  tree_set.add("Green");
  tree_set.add("Orange");
  tree_set.add("White");
  tree_set.add("Black");
  // Print the tree list
  for (String element : tree_set) {
    System.out.println(element);
    }
 }
}

Sample Output:

Black                                                                  
Green                                                                  
Orange                                                                 
Red
