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
