1. Download:

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

My computer is 64-bit, so the download version is jdk-8u121-windows-x64.exe

2. Installation:

I choose to install by default, or I can customize the installation path. To install JRE after installing JDK, it is recommended that you install two JDK and JRE installation paths side by side (the default installation is created side by side, which can be ignored), as shown in the following figure.

3. Configure environment variables:

1. Open the environment variable configuration. Computer → properties → advanced system settings → advanced → environment variable, which is configured in the system variable.

two。 Configure JAVA_HOME. New, variable name JAVA_HOME, variable value, jdk path, my path is C:\ Program Files\ Java\ jdk1.8.0_121, save.

3. Configure CLASSPATH. New, variable name CLASSPATH, variable value,.;% JAVA_HOME%\ lib;%JAVA_HOME%\ lib\ tools.jar (the first semicolon is preceded by a dot).

4. Configure Path. Open the Path variable and add% JAVA_HOME%\ bin;%JAVA_HOME%\ jre\ bin before the value of the variable

Fourth, verification:

Run cmd, type java-version, and display the java version successfully.
