Java String Tokens Hacker Rank Solution

Problem :

Given a string,8 , matching the regular expression [A-Za-z !,?._'@]+, split the string into tokens. We define a token to be one or more consecutive English alphabetic letters. Then, print the number of tokens, followed by each token on a new line.

Note: You may find the String.split method helpful in completing this challenge.

Input Format

A single string, 8.


  • 8 is composed of any of the following: English alphabetic letters, blank spaces, exclamation points (!), commas (,), question marks (?), periods (.), underscores (_), apostrophes ('), and at symbols (@).

Output Format

On the first line, print an integer,n, denoting the number of tokens in string 8 (they do not need to be unique). Next, print each of the n tokens on a new line in the same order as they appear in input string 8.

Sample Input

He is a very very good boy, isn't he?

Sample Output



We consider a token to be a contiguous segment of alphabetic characters. There are a total of  such tokens in string , and each token is printed in the same order in which it appears in string .

        /* Read input */
        Scanner scan = new Scanner(;
        String s = scan.nextLine();
        s = s.trim(); // so that .split() works properly
        /* Check special cases */
        if (s.length() == 0) {
        /* Split on all non-alphabetic characters */
        String [] words = s.split("[^a-zA-Z]+");
        /* Print output */
        for (String word : words) {
