In the above code, we have used StringTokenizer class that splits the string on the basis of " ".The method hasMoreTokens() of this class searches the words or tokens till the end of the string. The method nextToken() finds the word. If that word or token starts with a or e or i or o or u, then the word will store into the string vowels, otherwise the words will get stored into the string consonants. At last we have concatenated both the strings.
