The Java.util.TreeSet.clone() method is used to return a shallow copy of the mentioned tree set. It just creates a copy of the set.
Syntax:
Tree_Set.clone()
Parameters: The method does not take any parameters.
Return Value: The function just returns a copy of the TreeSet.
Below program illustrates the use of Java.util.TreeSet.clone() method:
// Java code to illustrate addAll()import java.io.*;import java.util.TreeSet; public class TreeSetDemo { public static void main(String args[]) { // Creating an empty TreeSet TreeSet<String> tree = new TreeSet<String>(); // Use add() method to add elements into the Set tree.add("Welcome"); tree.add("To"); tree.add("Geeks"); tree.add("4"); tree.add("Geeks"); tree.add("TreeSet"); // Displaying the TreeSet System.out.println("TreeSet: " + tree); // Creating a new cloned set TreeSet cloned_set = new TreeSet(); // Cloning the set using clone() method cloned_set = (TreeSet)tree.clone(); // Displaying the cloned_set System.out.println("The cloned TreeSet: " + cloned_set); }} |
Output:
TreeSet: [4, Geeks, To, TreeSet, Welcome] The cloned TreeSet: [4, Geeks, To, TreeSet, Welcome]
