Install ideaIU14 and add desktop shortcuts under Ubuntu

1 Installing the JDK

Here to install the official jdk1.7.79 for example, JDK7 Web page: http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

1.1 Downloads jdk1.7.79

$ wget http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.tar.gz

1.2 Decompression

$ TAR-ZXVF jdk-7u79-linux-x64.tar.gz

1.3 Installing to /USR/LIB/JVM

$ MKDIR/USR/LIB/JVM

$ MV JDK1.7.0_79/USR/LIB/JVM

$ CD/USR/LIB/JVM

$ mv jdk1.7.0_79 Jdk7

1.4 Configuring environment variables

$ gedit ~/.BASHRC

Add at the end of the open file

Export JAVA_HOME=/USR/LIB/JVM/JDK7

Export JRE_HOME=${JAVA_HOME}/JRE

Export Classpath=.:${java_home}/lib:${jre_home}/lib

Export Path=${java_home}/bin: $PATH

Save the exit and enter the following command to take effect

$ source ~/.BASHRC

1.5 Configuring the default JDK (since some Linux distributions already have default JDK, such as OPENJDK, to make the JDK version we just installed can be the default JDK version, configure as follows)

$ sudo update-alternatives--install/usr/bin/java Java/usr/lib/jvm/jdk7/bin/java 300

$ sudo update-alternatives--install/usr/bin/javac Javac/usr/lib/jvm/jdk7/bin/javac 300

Note: If the above two commands do not find a path problem, just restart the computer and repeat the above two lines of code is OK.

Execute the following code to see the current various JDK versions and configurations:

$ sudo update-alternatives--config java

1.6 Testing

$ java-version

Appears as follows: Installation succeeded

Java Version "1.7.0_79"
