"Java Series" Java Development environment construction

Describe

This article focuses on building a Java development environment based on Windows 10 system, the main contents are as follows:

(1) Installation Information preparation

(2) Explain the installation process

(3) test whether the installation is successful

(4) Hello Word Test

1 Mounting Material preparation

Before the Java development environment is built, you need to prepare the 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 Explained

JDK Installation (remember the installation of the road, in the environment variable configuration required) and Eclepse are all part of the idiot-type one-click installation, here is skipped, a general explanation of the Windows 10-based system environment variable configuration.

Configure three environment variables: Home,classpath,path

Add Java_home variable

Install the JDK path: "C:\Program Files (x86) \java\jdk1.8.0_144"

Java_path Variable Configuration

If there is a path variable, add the following header: "%java_home%\bin;%java_home%\jre\bin;", if it does not exist, create a new variable path and add "%java_home%\bin;%java_ Home%\jre\bin;"

Java_classpath Variable Configuration (if you use more than 1.5 versions of the JDK, you can compile and run the Java program without setting the CLASSPATH environment variable.) )

Add Java_classpath Variable Value ".; %java_home%\lib\dt.jar;%java_home%\lib\tools.jar;"

3 test whether the installation was successful

Win+r, input cmd

Type the command: java-version,java,javac Several commands, the following message appears, indicating that the environment variable configuration is successful;

Enter Java-version (test JDK is installed successfully)

Input Java

Input javac (test environment variable is configured successfully)

4 Hello Word Test

Slightly.
