Configuring the Java Development environment

　　

The leader requires Java to do interface testing, so the first step is to build the Java development environment first.

First step: Install the JDK

1, understand

JVM (Java virtual Machine-java vm)

JRE (Java runtime Environment-java Runtime Environment)

JDK (Java Development Kit-java Development Kit)

2. The JDK contains the JRE and JVM, so installing the JDK installs the JRE and JVM,JDK installation package refer to the Oracle official website address download: http://www.oracle.com/technetwork/java/javase/ Downloads/index.html

(Many versions, choose the appropriate version and the system for installation.) Installation steps Step by step next is good. Remember the above to choose Accept, otherwise cannot download yo. ）

Step Two: Configure Environment variables (Control Panel--user account--change user account--Change my environment variable on the left)

Java_home Configuring the JDK installation path

PATH to configure the location of the JDK command file

CLASSPATH Configuring the location of a class library file

1. Java_home: The system variable is not java_hone this variable, you need to edit the following: (Variable value is the installation address of the JDK.) ）

2. PATH: (Address of the bin under JDK)

3.CLASSPATH: (Address of the JDK under Lib)

--with "." Represents the current path

--with ";" Separated

--Enter the path of BIL

Step three: Verify that the Java environment is configured successfully

Win+r---cmd---Java or javac, congratulations on your successful configuration, you can start your Java coding journey.
