I am trying to compile a java class via command line (cmd), but I cannot, the error shown is:

'java is not recognized as an internal or external command, a operable program, or a batch file.

Screenshot of the prompt with the error:

I set the environment variables as follows:

JAVA_HOME: C:\Program Files\Java\jdk1.8.0_60

and

PATH:
C:\ProgramData\Oracle\Java\javapath;
C:\Program Files\Common Files\Microsoft Shared\Windows Live;
C:\Windows\system32;

Now it’s improved. By the way the environment variables were not configured correctly or the cmd you ran was with the old settings.

At the end of the PATH, add this: ;%JAVA_HOME%, ok and go confirming, close all cmd, open a new cmd and run javac or java --version.

Right-click on "My Computer" and then on estates.
In the "Advanced" tab click on "Environment Variables".
Under "System Variables" click on "New...", will open a little window for you...
Under "Variable Name" type "JAVA_HOME"
In "Variable Value" type the path where you installed JDK there top... in your case "C: Program Files Java jdk1.8.0_60". Ready, OK...
Now in "User Variables" look for a variable called "PATH", if there is no click on "New...", or click on "Edit..."
Who clicked on "New..." put as "Variable Name" the text "PATH" and as its value the text "%JAVA_HOME% bin
Who clicked on "Edit..." add at the end of the variable value o text "; %JAVA_HOME% bin"
Open a new command prompt and run javac
