It seems like all the Java files are there in c:\java

I changed System Variable so it looks like this:

Variable name: JAVA_HOME
Variable value: C:\java\bin\

I also tried putting the value in quotes.

When I try to run the javac command I get the is not recognized as an internal or external whatever message. However when I use it as "C:\java\bin\javac.exe" it works. But the java command works in command prompt without the full file path needed.

I'm stumped do you guys have any ideas?

Thank you for your help. I followed the instructions and made an environment variable pointing at C:\java\bin\ which is the directory moved java to and it still wont work. Any suggestions?

I recently installed JDK SE on my computer, I then moved the content of the bin folder to the windows directory so that I could use it without pointing to c:\java\bin every time. Now when I try to use the javac command I get the error shown below (I copied it by hand so there might be some errors but it's almost completely correct). I know it's not my program because i tried copying the hello world program from this website and I got the same error. Thank you for your help.
