Who is using s.split(...) and failing tests 3,6,7,10, change it to s.trim().split(...) and it will pass! You are welcome!

Issue encountered on some test case Tried inputing test using test cases and have expected output

    // Write your code here.

    String[] Splat = s.split("[ !,?._'@]+");
    System.out.println(Splat.length);
    for(String me : Splat)
    {
        System.out.println(me);
    }
    scan.close();
}

}

This is a classic string manipulation and tokenization challenge, often seen in programming exercises like those on HackerRank. New Play Exchange Login

import java.io.; import java.util.; import java.util.regex.*; public class Solution {

public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);
    String s = scan.nextLine();
    scan.close();
    Pattern p = Pattern.compile("[A-Za-z]+");
    Matcher m = p.matcher(s);

    List<String> tokens = new ArrayList<>();
    while (m.find()) {
        tokens.add(m.group());
    }

    System.out.println(tokens.size());
    for (String token : tokens) {
        System.out.println(token);
    }
}

}

Test number 3,6,7,10 are being failed despite giving expected output in individual tests. Used java 8 and 15. Doesn't make any different

Scanner scan = new Scanner(System.in);
String s = scan.nextLine();
String[] strArr = s.split("[, .'!?_@]+");
System.out.println(strArr.length);
for (String str: strArr) {
	System.out.println(str);
}
scan.close();
