Java Installation and Configuration development environment

This article will document some of the steps for installing Java and Configuring the Java environment, as well as the configuration of the Java-based extensible development platform Eclipse's Android development environment.

Preparation Tools

1.JDK Downloads

The differences between Java SE, Java EE, and Java me on the left column bar are:
Javase is a specific implementation of the JDK JVM and its own API collections. Java EE is a set of canonical interfaces developed based on Javase. Please note that the specification is not implemented. Publishers themselves to implement these interfaces. Javame is a set of API interface specifications that run specifically for embedded devices. such as the Set-top box program.
All in all, SE writes desktop applications, EE writes Web applications, ME writes mobile apps, but now me is replaced by Android. Here we choose SE.

Select Java se->downloads after entering the Web page

Select the computer corresponding to the version on the line.

2.Eclipse Downloads

Download the success is OK.

3.Android SDK


Currently the latest version is 24.4.1, according to the computer system selection download, here I choose Windows Download.

4.ADT

After the last download all the tools are as follows:

The next one is installed.

JDK Installation

Personal advice You can create a folder Java under the drive letter you want to install, and then create two new folders under Java files JDK and JRE. Although it can be created later, it is well organized to create it in advance.
Double-click to run the downloaded JDK, the way will be two times the file installation location prompt, the first time is the installation location of the JDK, the second is the installation location of the JRE, respectively, the installation location is selected as
D:\JAVA\JDK and D:\Java\jre, that is, the previously created folder, after completion, check that there are no loaded, shortcut keys windows+r, enter the cmd command, and then enter Javac:

The reason for this is because no installer does not automatically help you add environment variables, so you need to do this manually:
1. Environment variables, advanced system settings, computer--(right-click) properties

Add the JDK path you installed in path, such as MeD:\java\jdk\bin
2. Add a Java_home entry under System variables to store the JDK's installation path:

JAVA_HOMED:\java\jdk

3. Restart your computer
4.cmd->javac:

The appearance of this represents success.

Eclipse installation

Double-click the Eclipse-inst-win64.exe file to download the corresponding IDE, where I chose the for Eclipse committers version

Wait for the installation is OK, turn off the program regardless of the first.

Android SDK Installation

1. Double-click the previously downloaded SDK file,
。
Keep next down, after the installation is successful, add the installation path to the system variable as well.
2. Restart
3.cmd->android-help

The emergence of the above is a success.

ADT Installation

Complete the above steps, and a Java development environment is built.
At the same time, eclipse is actually very rare for me, because the birth of Android studio really creates a better development experience for developers, and it's handy if you can learn about the operations of Android studio. Android Studio installation can refer to this blog
