Thread: Little easy to fix problem

Recommended reading: Pattern (Java Platform SE 6)

That link talks about regular expressions. Basically, regular expressions tell you whether a particular pattern (like a number) can be found inside another String.

Hint- The pattern you're looking for is any number of any kind of character, then a number, then any number of any kind of character, right?

Yep. So your next step is to throw together a regular expression that matches that pattern.

Google is your friend for example regular expressions. But here's one that tests whether the String "cat" can be found in another String:

Pattern p = Pattern.compile(".*cat.*");
		 Matcher m = p.matcher("test cat test");
		 boolean b = m.matches();
 
		 System.out.println(b);

What have you tried? Which part of that are you stuck on? Iterating over names? Using an if statement? Something else? You can't just keep asking general questions, as they're actually much harder to answer than specific questions about code.

Post an SSCCE (not your entire program) that demonstrates what you've tried and where you're stuck and ask a specific question, and we'll go from there.
