Download, install, and configure the JDK

Download

Download page: http://www.oracle.com/technetwork/java/javase/downloads/index.html

The installation package of the JDK comes with a JRE, which, during installation, determines whether the JRE needs to be installed depending on the current system's actual situation, so you only need to download the JDK's installation package.

Installation

The installation process is nothing to say.

Configuration One: New system environment variable Java_home

Variable name	Java_home	Note: Variable names must match exactly
Variable Value	C:\Program files\java\jdk1.8.0_25	Note: Fill in the JDK installation path on the current system

If the installer is not configured automatically, you can manually add it, less than 1 minutes:

Configuration two: Modifying an existing system environment variable path

Variable name	Path	Note: This environment variable generally does not require a new
Variable Value	%java_home%\bin	Note: Append the current value after the line

Other configurations

Some of the information on the web in the JDK configuration, but also mention the environment variables such as classpath and%java_home%\jre\bin variables such as value.

Well, based on my experience with Android studio and Eclipse, it's enough to complete configuration one and configure two. But it's more harmless, you know.

Check

To check if the JDK is installed successfully, you can enter "Java–version" in the Command line window and if you see the information shown, the installation is successful:
