Return:

It returns a shallow copy of the set.

Example 1

import java.util.*;
public class JavaTreeSetClonExample1
{
  public static void main(String as[]){
  TreeSet <Integer>obj = new TreeSet<Integer>();
  TreeSet <Integer>obj1 = new TreeSet<Integer>();
  obj.add(2);	
  obj.add(8);
  obj.add(5);
  obj.add(1);
  obj.add(10);
  System.out.println("TreeSet: " +obj);
  obj1 =(TreeSet<Integer>) obj.clone();
  System.out.println("Elements in Cloned TreeSet: " + obj1);
  }
}

Output:

TreeSet: [1, 2, 5, 8, 10]
Elements in Cloned TreeSet: [1, 2, 5, 8, 10]

Example 2

import java.util.*;
public class JavaTreeSetCloneExample2
{
  public static void main(String as[]){
  TreeSet <String> obj = new TreeSet<String>();
  TreeSet <String> obj1 = new TreeSet<String>();
  obj.add("B");	
  obj.add("b");
  obj.add("A");
  obj.add("a");
  obj.add("6");
  obj.add("3");
  obj.add("9");
  obj.add("1");
  System.out.println("TreeSet: " +obj);
  obj1 =(TreeSet<String>) obj.clone();
  System.out.println("Elements in Cloned TreeSet: " + obj1);
  }
}

Output:

TreeSet: [1, 3, 6, 9, A, B, a, b]
Elements in Cloned TreeSet: [1, 3, 6, 9, A, B, a, b]
