How to find path where jdk installed?

Question

I'm a newbie to Linux so please forgive me for asking such stupid question!

I'd installed jdk1.7.0.rpm package in RHEL6.
Where I do find the path and to execute my first java program?

Answer 1

You can list the installed files with

rpm -ql packagename

You will see somewhere a bin directory with java executable

But if the JDK RPM was correctly installed you should already find java in you path.

Try

javac MyFirstJavaClass.java

and if everything compiles

java MyFirstClass

(If you didn't change anything the current directory . should already be in your class path)

Answer 2

Try either of the two:

$ which java

$ whereis java

For your first java program read this tutorial:
