ubuntu安装JAVA 如何选择OK

I feel like this is an extremely simple question, but for some reason, I simply cannot figure out how to do it. I am very green when it comes to Linux, but I'm really wanting to learn.

For some strange reason, I cannot figure out how to select 'ok' in the Terminal for Configuring sun-java5 jre.

Currently, I'm reading through the Ubuntu wiki page to try and get a basic understanding: http://ubuntuguide.org/wiki/Ubuntu:Hardy

I've attached a screen shot (figured out how to do that in Ubuntu!) of the terminal window to help explain where I'm stuck.

Anyone? I tried searching for an answer, but I just couldn't find anything.

Thanks in advance!

 

只要按TABLE键，然后再选择OK就只可以了Press the Tab key to highlight the <OK> and Return key to accept it.
