Note that Perl also has closures, which Java doesn't have. In some refactoring cases, you might want to use a closure instead of a method - it gives you some of the benefits private methods give you in Java.

But for me, there's a large difference between storing something in a temporary variable, and using a method. Assuming the temporary variable isn't tied, once you put a value in there, you get back the same value each and every time. With a method, that's less clear, certainly when seen from the caller's perspective. For instance:

my $v1 = $v2 + $v2; my $v3 = $self->m1 + $self->m1;
The first is equivalent to 2 * $v2, but it's not clear whether the latter is equivalent to 2 * $self->m1, until you know what m1 does.

And that's a language agnostic issue.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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.
