Newbie on debian and trying to make Java 7 the default java version used

Question

2 questions.

1. After installing the Oracle Java 7 on my new Debian local box, I opened up a terminal and executed the following command:

java -ver

Answer 1

sudo update-java-alternatives -s ... will configure all the alternatives at the same time update-java-alternatives -l lists the alternatives

Answer 2

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.
