Convert TreeSet content to array

DrRakha

Convert the content of ordered Tree set into a normal java array.

Code:

import java.util.SortedSet;
import java.util.TreeSet;

public class ArraysWork {

    public static void main(String[] arr) {
        SortedSet<String> stringsTreeSet = new TreeSet<String>();
        stringsTreeSet.add("keen");
        stringsTreeSet.add("adjust");
        stringsTreeSet.add("zip");
        stringsTreeSet.add("diagnosis");
        stringsTreeSet.add("claim");
        stringsTreeSet.add("play");

        // Printing the content of the Tree set
        // Notice that the strings are ordered alphabetically
        System.out.println("---------------------------------");
        System.out.println("Elements in Tree set : " + stringsTreeSet);
       
        /*
         * Show first element
         */
        System.out.println("---------------------------------");
        System.out.println("Element at first:"+stringsTreeSet.first());
        System.out.println("---------------------------------");
        /* 
        Copy to array of string...
         */
        Object[] strArray = stringsTreeSet.toArray();
        /* All elements of array... */
        for (int i = 0; i < strArray.length; i++) {

            System.out.println("Array element : " + strArray[i]);
        }

    }
 

The output is:

Code:

---------------------------------
Elements in Tree set : [adjust, claim, diagnosis, keen, play, zip]
---------------------------------
Element at first:adjust
---------------------------------
Array element : adjust
Array element : claim
Array element : diagnosis
Array element : keen
Array element : play
Array element : zip
