O2 Environment Configuration:

Right click on the computer----properties----Click Advanced System settings------environment Variables---"In the system variables:

1) Create a new java_home variable in the system variable, the value of the variable is: C:\Program files\java\jdk1.6.0_14 (fill in according to their own installation path) (Note: No sign before and after) is the path of the circle in the diagram copy and paste

2) New CLASSPATH variable, variable value is:.; %java_home%\lib;%java_home%\lib\tools.jar (note: Front pastry, semicolon, back semicolon)

3) Add the variable value in the path variable (existing without new):%java_home%\bin;%java_home%\jre\bin (Note the ";" between the variable values) (Note: Write at the front of the original variable value is unsigned, followed by a semicolon)

The installation and configuration are complete by this step.

O3 Verify the configuration is successful:

O4 the problems and solutions I personally encounter

Issue: Javac always show not internal or external commands during configuration environment

Workaround

I personally changed path :%java_home% in the system variable to full path C:\Program files\java\jdk1.6.0_14 (filled in according to your own installation path)

This is the path in java-home .

change in Classpeth . ; C:\Program files\java\jdk1.8.0_131\lib\dt.jar;c:\program Files\java\jdk1.8.0_131\lib\tools.jar(fill in% according to your installation path) Java-home% as in the path above note that the starting point cannot be lost)

I don't know the exact reason.
