I added the Path to the JDK in Advanced settings and rebooted my system. The Command Prompt recognizes my version of java but not javac.

I am running Windows 7 64bit OS and JDK 1.8.0_91
Please Help, Thank you

Have you set your environmental variables in System Properties? Sometimes you need to do that
(Control Panel -> System -> Advanced System Settings)

Welcome to the Ranch

Are you sure you are recognising the 8u91 version? Try the following two instructions:-
java -version
javac -version
The error message you are getting is very common, and ZG has already explained it. We have an FAQ which covers it. The Java™ Tutorials have a section which covers the same problem.

If your installation includes java.exe but not javac.exe then perhaps you only installed a JRE (Java Runtime Environment) instead of a JDK (Java Development Kit). Or perhaps you set your PATH variable to point to the JRE part of your installation. Have a look at the folder where your PATH points to and see if it has java but not javac. On my machine which is very similar to yours (at least the bit you described) my PATH points to C:\Program Data\Oracle\Java\javapath, among other things. When I install new versions of Java I never have to change anything. So perhaps your PATH has that at the beginning and you added something else at the end?

And, welcome to the Ranch!

Environmental variables have been set- The PATH to JDK has been added and a reboot has occurred.
In Command Prompt I entered java -version and received recognition for
java version "1.5.0_91", Java SE Runtime Environment (build 1.8.0_91-b14), and Java Hotspot 64bit Server (build 25.91-b140
I read the facts page and did not see a solution I have not attempted
javac.exe is in the bin folder of the PATH i designated
Do I for some strange reason have to designate a path directly to the bin folder of JDK to access the compiler?
And thank you for the timely replies and the welcome

Hello
To answer the replies in order
1) Environmental variables have been set- The PATH to JDK has been added and a reboot has occurred.
2) In Command Prompt I entered java -version and received recognition for:
java version "1.5.0_91"
Java SE Runtime Environment (build 1.8.0_91-b14),
Java Hotspot 64bit Server (build 25.91-b140
I read the facts page and did not see a solution I have not attempted
3) javac.exe is in the bin folder of the PATH I designated
Do I for some strange reason have to designate a path directly to the bin folder of JDK to access the compiler?
I will look at the FAQ's page again to see if there is anyhting I may have missed.
And thank you for the timely replies and the welcome

It looks like you were typing on a numeric keypad, because you typed "1.5.0" instead of "1.8.0" there. Confused me for a few seconds before I figured out what you must have done.

Anyway could you copy your PATH variable and post it here?

The output with 1.8.0_91 etc looks correct for the java tool, and that PATH looks correct too. Please copy and paste such output to save time and prevent such typos: instructions here. Yes, the Java® PATH entry usually starts with the drive letter (on Windows®) and ends bin.
To confirm you have it working try
javac -version
and try to compile a file.
