java --version doesn't work in the command line

Question

I tried java --version in the command line and I get :

Unrecognized option: --version
Error: Could not create the Java virtual machine
Error: A fatal exception has occurred. Program will exit.

Everything was working fine until I installed jre 7 (I had jdk 1.6 preinstalled ) So, I uninstalled the previous versions, restarted and then installed fresh jdk 7u5 windows i586.

Still I get the same problem. Can anyone help me with this?
I am unable to install and run maven for this reason.

For what it's worth, `java -help` prints out usage information; doing that would've given you the solution immediately. — Dennis Meng, Jul 18 '12 at 23:40
@DennisMeng yes, *if* you know that you need to write just one dash. — Nils Lindemann, Jun 24 '20 at 11:39

You used two - marks. Try with one: java -version.

Update: Since Java 9 java and javac commands support both --version and -version.

This basically repeats the information provided in the answer from Pshemo from 2012. – Mark Rotteveel Aug 03 '22 at 08:54
