To configure environment variables:

The principle of configuring environment variables and Windows under Linux is the same, which is to make the path of the JDK a global variable, with the text editor gedit (if not installed can use VI) to open/etc/profile, at the end of the file to add

Export java_home=/usr/java/jdk1.6.0_45

Export path= $JAVA _home/bin: $PATH

Export classpath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar

Jdk1.6.0_45 change to the folder name of the JDK you installed

Log off after saving

Let the file take effect:

. /etc/profile

Test: Input Java,java-version
