        System.out.println("String: " + s);

what is the problem in my code i'm new in java

Welcome to SO. Please be more specific - "what is the problem" and "I'm getting error" helps no one to answer. Error message and description of expected behaviour usually help. — no id, May 06 '18 at 23:11

Problem is here:

String s = scan.next();

Introduce addtional line to skip newline:

String s = scan.next();
scan.nextLine(); /* add this */

OR

Replace that line with:

String s = scan.nextLine();

Since the question isn't clear, I'm guessing you have the problem with the string.

This will reads until there is a space.

String s = scan.next();

If you want to read a string after the space consider doing this:

String s = scan.nextLine();
