Java Learning Notes--1, JDK, and Eclipse installation

The first step in learning Java is to install the Java development environment. The JDK is the Java Development toolset.

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

Java is divided into three systems, namely:

Java SE (J2se,java 2 Platform Standards Edition, Standard Edition);

Java EE (J2ee,java 2 Platform, Enterprise Edition, Corporate Edition);

Java ME (J2me,java 2 Platform micro Edition, mini version).

First we want to download the JDK we need:

Download down nothing to say, go straight to the next, until finished. After installation we need to configure the environment variables because Windows does not know where you have installed the JDK.

Environment variable configuration:

Environment variables, advanced system settings, properties---------

To facilitate future maintenance, first create a new variable under the system variable named: Java_home Value: The path of the JDK;

Example: D:\Java\jdk1.7.0_67

The%java_home%\bin is then added to the value of the path variable;

Verify the success, Win + R, open run, enter cmd OK to open the command line.

Enter "Java" and "Javac", if not displayed Java is not a system command to represent the configuration succeeded.

Eclipse Installation:

Is the JDK installed after the installation is not very excited, we continue to install the Java Artifact--eclipse, first post an introduction to Eclipse:

Eclipse is an open-source, Java-based, extensible development platform. For its part, it is just a framework and a set of services for building a development environment through plug-in components.

After the introduction, Eclipse is a Java development environment, and then we'll show you how to install:

eclipse:http://www.eclipse.org/downloads/

Depending on your system version, choose 32-bit or 64-bit version download, it is worth noting that if the system version is 64-bit, but your JDK download 32-bit, then eclipse must also download 32-bit.

The downloaded eclipse is a compressed package that can be used directly by decompression.

Is that all? --certainly not finished, for the English small white, also must be Chinese, otherwise the watch is anxious!

First look at the version of Eclipse:

Help menu, about Eclipse, in the popup dialog box, locate your Eclipse version ID.

Open website: http://www.eclipse.org/babel/

Copy the corresponding version number:

Back to eclipse's menu, help, Install New software ...

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/59/78/wKiom1TTbtyw91L4AACijRdiaoE561.jpg "title=" Qq20150205212145.jpg "alt=" Wkiom1ttbtyw91l4aacijrdiaoe561.jpg "/>

Name to fill, the location of the paste just on the site copy of the address, completed after determination. Wait a minute, find Chinese (Simplified), click the Left expand button, find the highest percentage of the hook (why do you want to find the highest percentage of it?). I do not know, the phenomenon of conformity, hehe! ), the download completes after the restart can complete the Chinese.

Here, JAVA_JDK and Eclipse are already installed. Next we can learn more about Java syntax.
