Hello asheets and Jarrod C. Thanks, to both of you, for your responses.
asheets, after typing in the commands you showed, I get the following outputs:
~$ java --version
The program 'java' can be found in the following packages:
Try: sudo apt-get install <selected package>
~$ uname -a
Linux evansste-KM400-8235 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:18:00 UTC 2015 i686 i686 i686 GNU/Linux
Hopefully that helps to satisfy your curiosity. Let me know if you have any more questions.
Thanks for your suggestion, Jarrod C. I didn't know that Windows 7 offered either of those functions. That's a bit impressive. However, I've already made up my mind to never buy another version of Windows. I stop at Windows XP.
Ironically, I recently made a post, in an Adobe forum, on this very issue.https://forums.adobe.com/thread/547150
It's an old thread, and my post is the very last one. But if you don't want to read it there, I'll say some of it again here.
I won't go back to Windows because I agree too much with the Linux philosophy. It's the philosophy that says that people ought to be able to make their computers do what they want them to do. We own our machines, right? We paid for them. So why should we have to keep paying for operating systems that force us to change setups that we already like?
This last situation has made me a true Linux believer. If it weren't for Linux, I'd have to re-buy an operating system, that I already own (just a different version), in order to make it work with my new hardware. Your solution is a perfect example of this. I'd have to buy Windows 7 in order to get Windows XP to work. It's great to know that Windows 7, at least offers this feature. Otherwise, I'd be stuck with the Windows 7 interface, whether I liked it or not. I went through the same issue with all of my previous Windows upgrades, starting with Windows 95.
I could go on an on on this subject, but the short story is that Linux saved my bacon. I can use my new hardware without having to spend more money on an operating system that behaves differently than what I'm used to using. Lubuntu looks, and works, exactly the same on all of my systems; both new and old. I don't have to re-learn anything, or accept changes that I don't like. I can take advantage of the new hardware advances without changing the way that I operate my computer. I'm grateful to the Linux developers, and general Linux community, for that.
In any case, I do appreciate your input. A while back, I briefly owned a laptop that came with Windows 7 installed on it. I was bummed that I couldn't install MATLAB on it. Had I known, what you just taught me, I could have solved that problem back then. So it's good to know. I also appreciate anyone who takes the time to help answer my questions. All of this knowledge is good knowledge, and I know that your time is valuable. So, once again, thank you.
