Example:
In the example below, the java.util.TreeSet.clone() method is used to create a clone of the given TreeSet.
import java.util.*;
public class MyClass {
public static void main(String[] args) {
//create a treeset
TreeSet<Integer> Set1 = new TreeSet<Integer>();
//populating Set1
Set1.add(10);
Set1.add(20);
Set1.add(30);
Set1.add(40);
//print the content of Set1
System.out.println("Set1 contains: "+ Set1);
//create a copy of Set1 into Set2
Object Set2 = Set1.clone();
//print the content of Set2
System.out.println("Set2 contains: "+ Set2);
}
}
The output of the above code will be:
Set1 contains: [10, 20, 30, 40] Set2 contains: [10, 20, 30, 40]
