What is the home directory for JDK?

Question

I am having a problem in selecting home directory for JDK. Even though I have selected the following path: "C:\Program Files (x86)\Java\jre1.8.0_91", it keeps showing the error: "The selected directory is not a valid home for JDK". My java folder has two folders- bin and lib. Window for selecting home directory

Kindly help me in selecting home directory. Thank you!

You have currently located a JRE, or Java Runtime Environment. That does indeed contain a java executable and can launch JVMs, but it's not made for development, rather more as a "Java client". For example if you look into it's /bin folder, you won't find the javac executable needed to compile.

What you need is a JDK, or Java Development Toolkit. It contains all the JRE contains, with additional tools for development. You can find it for download on the Oracle website.
