Java environment variable configuration in Win10

First, you should have installed the Java JDK (if not installed JDK, please jump to this URL: http://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html)

The author installed jdk-8u91-windows-x64

Next, I will focus on how to configure the Java environment variables so that I forget to make a backup one day later.

(Note: The Java environment variable configuration of win10 is slightly different from that of other windows versions)

Right-click the "properties" option of "this computer" on the desktop

 

Select "Advanced System settings"

 

Click the "environment variable" option below

 

The specific configuration process is as follows:

Click "new" under "system variables ".

 

Fill in "Java_Home" in "variable name"

"Variable value" is the JDK installation path. The author's path is "D: \ Program Files \ Java \ jdk1.8.0 _ 91"

Click "OK"

 

Find "Path" in "system variable"

 

Select "Path" and click "edit ".

 

Select edit text on the right and copy all the quotation marks to "% Java_Home % \ bin; % Java_Home % \ jre \ bin ;", to the beginning of the "variable value" column, "OK"

 

In the "System variables" column, "new", "variable name" is "CLASSPATH", and "variable value" is ".; % Java_Home % \ bin; % Java_Home % \ lib \ dt. jar; % Java_Home % \ lib \ tools. jar "," OK"

 

Click "OK" at the bottom of "environment variables"

 

Return to the desktop, press Win + R, and Enter cmd"

 

Check whether the Java environment is configured successfully.

Enter "java"

 

Enter "javac"

Enter "java-version"
