Yes, you can make all static classes and put a driving script in a main method in Java. But, not matter what, you must put all of that in a class. Hence the charge: Java is Object Oriented Only. We say this, because every single line of operative code must be in a method and every single method must be explicityly placed into a class. You can't just write a driver:

print "driver starting\n";
`call_system_util1`;
`call_system_util2`;
print "driver finished\n";

The equivalent code in Java must be in a method of some class. That's overkill in this case and it buys nothing except tedious typing, which is why we make the charge and it sticks.

There are two subtle bits of syntatic sugar here. First, Perl puts things in the main package by default. Second, code does not have to appear in a method/sub/function/whatever. It can just go in a driving script. Perhaps these differences seem small, but they are real.

• 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 How to display code and escape characters are good places to start.
