How to install the JDK and Eclipse configuration method under Linux

First, install the Java development environment

1,jdk-6u33-linux-i586.bin, after downloading the original directory is:/home/downloads/

2, will download the file to place you need, here I put in

CP JDK-6U33-LINUX-I586.BIN/USR/SHARE/JAVAJDK

Note: usr: is unix software resoure, the main place some common software

3, CD/USR/SHARE/JAVAJDK change the file permissions, so that it can run:

sudo chmod u+x jdk-6u33-linux-i586.bin

Note: chmod is the right to change files, because you have just downloaded the file can not be executed by default, so you should add

4. Run the file: sudo./jdk-6u33-linux-i586.bin, so far,

Note: for the suffix name. bin can be run directly

/usr/share/javajdk

There is a bin package jdk1.6.0_37 under the directory, and a folder with the same name as the uncompressed file.

5, enter in the terminal:

sudo gedit/etc/environment

Add the following at the end of the file:

Export java_home=/usr/share/javajdk/jdk1.6.0_33

Export JRE_HOME=/USR/SHARE/JAVAJDK/JDK1.6.0_33/JRE

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

6, configure JDK environment variables in profile:

sudo gedit/etc/profile,

and add the following lines:

#set Java Environment

Export java_home=/home/apple/javaidetools/javajdk/jdk1.6.0_31

Export JRE_HOME=/HOME/APPLE/JAVAIDETOOLS/JAVAJDK/JDK1.6.0_31/JRE

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

Export path= $JAVA _home/bin: $JAVA _home/jre/bin: $PATH: $HOME/bin

7, log off the user, and then enter Java-version in the terminal to try

Remember to log off the user again
