How do I compile .java into .class?

I dont know how to do this and i dont want that online one, I need to compile them manually (prob from .bat?) If you know how to compile java files it'd be very helpfull if you could post it.

thanks

goto the command line....(Consider you have your path variables set)
get to the current directory the file is in:
cd/directory

then to compile:

javac FileName.java

then to run:

java FileName

I get this error:

'javac' is not recognized as internal or external command, operable program or batch file.

I think I have to set it up in my Environment Variables saying the class path to my java, But i dont know what it is :'( Anyway to fix this?

Ah, never saw that, what do you have your path variables set as? I've tried this

PATH
C:\Program Files\Java\jdk1.5.0_03\bin

and it didnt work

**Edit:

I played around and it worked! so if someone else is having trouble

right click "my computer" go to "advance" go to envirmental variables > click on "new" and type this in if you have jdk 1.5.0_03 installed


PATH
%:\Program Files\Java\**java version**\bin

for me it was C:\Program Files\Java\jdk1.5.0_03\bin


if that doesnt work, do the same thing and estead of typing in PATH, type in JAVAC.

;)

You can always use the -classpath switch.
C:\jdk1.5.0_03\bin> java -classpath C:\classfiledir; classfile
