1. installation material preparation

Before building a java development environment, you must prepare JDK and Eclipse.

1.1 JDK

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

 

1.2 Eclipse

: Http://www.eclipse.org/

 

2. Installation Process

Jdk installation (keep in mind the installation path, which is required during environment variable configuration) and ecs0se are all silly one-click installation. Here I will skip this step and explain the configuration of environment variables based on windows 10.

Configure three environment variables: HOME, CLASSPATH, and PATH.

 

Add JAVA_HOME variable

Jdk installation path: "C: \ Program Files (x86) \ Java \ jdk1.8.0 _ 144"

JAVA_PATH variable configuration

If the PATH variable exists, add "% JAVA_HOME % \ bin; % JAVA_HOME % \ jre \ bin;" in the header. If the PATH variable does not exist, create the PATH variable, add "% JAVA_HOME % \ bin; % JAVA_HOME % \ jre \ bin ;"

 

JAVA_CLASSPATH variable configuration (if JDK 1.5 or later is used, you can compile and run Java programs without setting the CLASSPATH environment variable .)

Add the JAVA_CLASSPATH variable value ".; % JAVA_HOME % \ lib \ dt. jar; % JAVA_HOME % \ lib \ tools. jar ;"

 

3. test whether the installation is successful.

 

WIN + R, Enter cmd

Type the following command:Java-version,Java,JavacThe following information is displayed, indicating that the environment variable is successfully configured;

Enter java-version to test whether jdk is successfully installed)

Enter java

Enter javac (test whether the environment variable is configured successfully)

 

4 Hello Word test
