With regard to the threading comment, you also test if a variable (list) is null and if it is - create a new ArrayList.

You should synchronise on the list which may mean not accepting null list variables.

As to anonymous classes, its 6 of one and half a dozen of another. They do provide the means of creating nice customisable blocks of code - I think its too easy, sometimes, to get caught up making everything defined types and using patterns (etc) but they are there. Additionally, I was thinking about your switch statement and how you are using integer vars to decide what to do. I was kind of hinting that it may be possible to keep your annonymous front end syntax and make the backend a little more complex and eliminate the switch statement as well as allow you to add more perlisms at a later stage. Note, I don't say it *is* possible, only that it *may be* possible :).

Finally, your code would look even better on 1.5 as static imports will allow (if there are no namespace collisions) for you to ignore the class name ie:
Math.abs()
becomes
abs()
So your looping methods will look more perl-ish still (hurrah!).

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
