Transferred from: http://jingyan.baidu.com/article/86fae346b696633c49121a30.html

The Java development environment is a cross-platform programming language that can be developed on Windows, Linux, and other operating systems. Small series used to do Linux C development, recently because of the work, the need for the Java development environment under Ubuntu to build, so write this experience, and everyone share, reference. This experience is divided into four steps:

1) Download JDK

2) Download eclipse

3) Installing the JDK

4) Install Eclipse

Tools/Materials

• Ubuntu
• Eclipse
• Jdk

One. Download JDK

1. 1

   As can be seen from the graph, after the output command java-version, the discovery system does not build a Java development environment.

2. 2

   To build the Java development environment, the first step is to install jdk!

   Web Links:

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

   Choose a version here.

   The mini-series Selects the Java SE 7u60, which you can choose according to your own needs.

   Download Eclipse's address: http://www.eclipse.org/downloads/

   , pay attention to the highlights:

   1) System Selection Linux

   2) Choose the version that is right for you, if you want to develop Java, choose the same as the small one, if you want to develop the C + +, select the C/D version

2. 2

   Look, in the small system, all the necessary software has been downloaded.

   END

Three. Installing the JDK

2. 1

   Enter the command to unzip:

4. 2

   , Decompression complete

6. 3

   To configure profile:

   Input command: Vim/etc/profile

8. 4

   This step is one of the most serious!

   1) Add Java_home path:

   Export java_home=/xxx/xxxx/jdk1.7.0_60

   This directory is the directory you extracted after the JDK, such as small, the extracted directory is:

   /opt/software/java/jdk1.7.0_60

   So the path to the small series is:

   Export java_home=/opt/software/java/jdk_1.7.0_60

   2) Add JRE path

   The small part is:

   Export JRE_HOME=/OPT/SOFTWARE/JAVA/JDK_1.7.0_60/JRE

   3) Configure Classpath Path

   Export classpath=.: $CLASSPATH: $JAVA _home/lib: $JRE _home/lib

   4) Configure path Path

   Export path= $PATH: $JAVA _home/bin: $JRE _home/bin
