Hey Bucky, attempting to learn Java and I notice you used JDK 1.6 for the examples and you're using XP. I've got windows 8.1 Did the thing with setting up the JDK as you directed, changed the new variable to Path and copied in the location C:\Program Files\Java\jdk1.8.0_40\bin Tried the javac cmd but I keep getting error message "javac is not recognised as an internal or external command, operable program or batch file. What do I do now? Wld like to do the lessons
