1.JDK Download:

Links: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Download the tar.gz compressed package that is marked with a red line.

Input in Terminal: Java-version

, displaying the JDK version and information indicating that the JDK installation was successful. (Explain, because I have installed the JDK, I just said the installation process, did not reinstall, so the previous download of the jdk1.8,

And the last display version is 1.6, so don't be too tangled on this issue ~ ~ ~)
