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); } } |
TreeSet: [4, Geeks, To, TreeSet, Welcome] The cloned TreeSet: [4, Geeks, To, TreeSet, Welcome]
