Your letter is asking for World Flame War ;-)
I learned many programming languages (from Forth to APL ;-),
of course including C, C++, Pascal, Assembler and, no surprise, Perl
For 3 years already I try to learn Java (it's "super cool", you know! And
widely used language;-). It's not that Java is difficult - no.
But I failed to go further than trying byte-counting example from Sun's
tutorial. First of all those "fluffy" statement for nothing (to much to
time), then too many times I came across versions/libraries
incompatibilities. ALl that depressed my desire to learn Java.
After some mental effort, I tried to start learning though.
And stopped - after "learning" that bytecounting
with Java works 500 times slower than in C and 250 slower
than in Perl...
I decided to return to learning Java later.
Probably, you will be luckier than me and will love it one day.
If you want to run Python on Java Virtual Machine, you can use
Personally I can't see cituation where Java could be preferrable, except
if your company forces you to use it for maintaining existing
Java is also preferable for an universal applet-writing, as all major
graphic browsers try to support it.
I also know that some Java programmers like Java. It seems
a matter of tastes ;-)
It must be also noted, that Python is higher level than Java:
Assembler - C - C++ - Java - Python
