Newbie on debian and trying to make Java 7 the default java version used
debian, linux
Solution
sudo update-alternatives --config java
Is the command to swap it i believe.
You can then call
which java
and it should reference the version selected.
Problem
2 questions. - After installing the Oracle Java 7 on my new Debian local box, I opened up a terminal and executed the following command: java -version When I did that it states: java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing) I installed the Java 7 JDK and Java 7 JRE in the following directories respectively: /usr/lib/jvm/jdk1.7.0 /usr/lib/jvm/jre1.7.0 - Is there a way to remove the java-6-sun and java-6-sun-1.6.0.26 folders as well or will it hurt just to leave them there? Any help/direction on these 2 questions would be appreciated. Regards.
