PHP - Perl - Java

Hi,
just wondering: is there anything which java cannot do, what only can be done using PHP or Perl? or where it could by wiser to use
PHP or Perl INSTEAD of java?
I have to decide if I should choose a training
course either in PHP/Perl or intenisfy my
java studies.
Any suggestions from you experienced folks?
thank you!

I would suggest taking the Java course. There is more demand for it in the workplace, and once you know Java you could learn PHP and Perl very easily on your own. It will also be very easy to work in C#.

If you already have some Java courses under your belt, taking a course in an additional language can only broaden your horizons. If you do not have any Java courses, I would take Java.
PHP is basically open-source ASP. Nothing too difficult about it. I do prefer it to ASP though.
Perl is a jack-of-all trades language. If you ever intend on doing significant work in a Unix-like environment, it would be very beneficial to have Perl under your belt. It can simplify a great number of routine tasks and is often used these days as a replacement for sed/awk/shell-scripting.
You can of course also use Perl for cgi programming. Since perl can communicate directly with the operating system of the host it is running on, there is much you can easily do with Perl that would be more difficult with Java because of Java's security "features", as well as Java's insistance on write-once-run-anwhere. For instance, if I wanted to make a web-based application that controlled or monitored various processes running on a server, Perl would be the way to go over Java.
The language of choice for any particular application depends on the job the application needs to do, so it always helps to have as many tools in the toolbox as possible.

hi John, Hi jason,
thank you for your comments!
I decide to first intensify java and afterwards
lern perl "easily"!
