but it seems there still is no working java applet on my computer, i cannot activate java in my browser and don't know if there is any java installed after all or not.

Q1: How do I delete old Java versions from my computer?

Q2: How can I know what version of ubuntu my computer is currently running?

Q3: What "type" of Java do I (ordinary user with no IT-knowledge whatsoever) need for my daily business and

Q4: How do I activate it in my browser?

Q1: How do I delete old Java versions from my computer?

That according to how you installed the other versions.


Q2: How can I know what version of ubuntu my computer is currently running?

In a terminal run:

lsb_release -a


Q3: What "type" of Java do I (ordinary user with no IT-knowledge whatsoever) need for my daily business?

That is according to what, exactly, your needs are.


Q4: How do I activate it in my browser?

There should be no activation whatsoever...just install. Here is the way that I install Java:

In a terminal run this command (after removing previously installed versions)


sudo add-apt-repository ppa:webupd8team/java && sudo apt-get update && sudo apt-get install oracle-java7-installer
