Identifying java file with out Javadoc

I would like to parse .java files which does NOT contain description about the class.

I am trying it to do with perl, but not able to get the approprate regexp to parse the following pattern

/**
 * Some text describing about the class
 *
 */

For example:

Class 开发者_StackOverflowCommunicationServer {
...
}

The description of class is missing. What regexp can be used in perl to parse this type of pattern?

Here is the what I tried but it does not work

while ( valid file handle) {
    my $isLine = $_;
    chomp($isLine);
    if ($isLine =~ m/^(\/\*\\*)/) {
        #if ($isLine =~ /[^\W]/) {  # Any non-word character.
        print $isLine ".\n";
    }
}

Or are you aware of any tool which help me to identify the non document class such as above?

Many thanks for input.

(/\\*\\*.*?\\*/[^;]*?class[^{]*)\\{

This thing can capture one class definition with a javadoc from a file. In case you don't have nested classes with javadoc and don't want to check them, you can use it. If this regex fails then your file does not have a class javadoc.

Make sure that your \s and . eat newline.

This may not always work. Did not test it much. Comment and I will answer.
