I am using Redhat 9. I want to learn java programming. I do have some "Hello World!" like example codes. I want to compile and see the results of those codes. I couldn't perform just by typing "gcj example_code.java". What is the way to compile java codes in linux platform?

get JDK from http://java.sun.com
but i think it you could be able to compile with command 'javac' first and then use 'java' command. i use RH 7.2 and I got both of them working fine. I don't recommend gcj...

gcj example_code.java --main=<class contianing main method> -I <directory to search for additional classes if req>

would do fine. Additional options you can specify are:

-o3 (Optimize for speed)
-o <output file name>
