Hi newsgroup,

not only that I have some trouble with my ArrayLists, I also need to check
Strings.

The problem is that I will have to check around 100 string if they meet the
specific criteria as follows:

XXX-000000

which means they have to start with three capital letters followed by a
hyphen and a six-digit number.

If anyone knows anything, I would be really thankful.

Once again best regards

Frank

Use a regular expression: [A-Z]{3}-\d{6}

In a Java string literal you have to escape the backslash, so this would
become

if ( Pattern.matches("[A-Z]{3}-\\d{6}", theStringToCheck) ) {
// accepted
} else {
// rejected
}
