How To Convert Treeset To Array

import java.util.Set;
import java.util.TreeSet;

public class TreeSetToArray {
   
    public static void main(String[] args) {
       
           Set<String> ts = new TreeSet<String>();
            ts.add("mumbai");
            ts.add("delhi");
            ts.add("kolkata");
            ts.add("chandigarh");
            ts.add("dehradun");

            // print treeset
            System.out.println("tree set is ="+ts);
           
            String [] arr = new  String[ts.size()];
       
            /*
             * Returns an array containing all of
             * the elements in this set
             */
           
            ts.toArray(arr);
       
            System.out.println("Print Array Element ");
           
            for (String str : arr) {
                 System.out.println("Array Element is = "+str);   
            }
   
    }
   

}




Output:



tree set is =[chandigarh, dehradun, delhi, kolkata, mumbai]

Print Array Element

Array Element is = chandigarh

Array Element is = dehradun

Array Element is = delhi

Array Element is = kolkata

Array Element is = mumbai
