error in running first java code

[Mirin Ghosh]

hi,

i am getting this error

C:\FirstJava>java hello
Error: could not open `C:\Program Files\Java\j2re1.4.2_18\lib\i386\jvm.cfg'

I have checked hello.class has been created under the folder "FirstJava"
One more thing:In my file structure it is "\Java\j2sdk1.4.2_18" not the one mention in the error.ie,"\Java\j2re1.4.2_18"
Please help me....

try "java -version" in the command prompt. It should display the version of the your JAVA Installation. Check you have installed the Java Runtime Environment also.

Hope this helps.

Make sure you've java executable in your PATH system variable.
When you're done, launch it like

java -classpath . hello

This way should run

[Mirin Ghosh]

where should i give this command:
java -version

ihave tried with

java -classpath but giving the same error.

[Vijitha Kumara]

where should i give this command:
java -version

I mentioned earlier in the command prompt(where you compile/run the java code/class).

After giving this command:

C:\Program Files\Java\j2sdk1.4.2_18\bin>java -version
java version "1.4.2_18"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_18-b06)
Java HotSpot(TM) Client VM (build 1.4.2_18-b06, mixed mode)

i am getting this.

I suggest reinstalling the JRE.
