First, install JDK

1. JVM (Java Virtual Machine-Java virtual machine)

JRE (Java Runtime Environment-Java Runtime Environment)

JDK (Java Development kit-Java Development Kit)

2. JDK includes JRE and JVM, so after installing JDK, the installation packages of JRE and JVM,JDK can be downloaded from the Oracle official website or from a third-party website. The official download address is provided below:

Http://www.oracle.com/technetwork/java/javase/downloads/index.html

(there are many versions, so choose the applicable version by yourself, omit the installation process, and then take the next step during installation.)

Second, configure environment variables

JAVA_HOME configure JDK installation path

Location of PATH configuration JDK command file

Location of the CLASSPATH configuration class library file

1. My computer (right button)-- > Properties

2. Advanced system settings-- > environment variables

3. There is no JAVA_HOME in the system variable, so you need to edit it as follows:

(the variable value is the path where JDK is installed)

4. PATH already exists in the system variable. Select PATH-- > Edit.

-- > enter the path to Bin first (separate other paths with semicolons)

5. The variables that come with the system do not have CLASSPATH and need to be added.

-- > use "." Represents the current path

Separate with ";"

-- > enter the path to Bil (for example, my path is: C:\ Program Files\ Java\ jdk1.8.0_60\ lib)

This is the end of the configuration, remember to press OK, not sure will not be saved by yourself.

Third, verify the configuration environment variables

Open and run à cmd à enter java/javac to verify (the effect of successful verification is as follows)

If you see this effect, congratulations on your successful configuration.
