Java - Yes or No?

On January 14 2013 I wrote about Java. This artcle should explain what Java is.

There mainly are two opposing views about Java on home computers around.

The first one says that Java is needed so rarely that it should not be on a home computer at all.

The second one just delivers it pre-installed on all computers sold over-the-counter in case you need it.

My personal view about Java is the following:

Have it installed for the (maybe rare) case that you need it.

My reasons are:

• If we are about to do something and get interrupted we tend to react somewhat frustrated. At this time we are very likely to get directed to the "wrong" web site for the download and we will probably get some sort of "blind passenger" or gunk software that we really neither need nor want.
  You doubt that? See the real life examples in this article.
   
• Over the years I had several very frustrated customers calling me and asking why Java was not installed. In every single case some well meaning but ill advised relative, friend or computer technician had removed Java.
   
• The few MB of disk storage space that Java needs are not an argument anymore; we are in  the age of 500GB and 1TB disk drives that a home user never will fill up. It is many years since I have seen a really full disk drive.

The price we have to pay is simple:

Keep Java up-to-date - and use common sense!

Here is the list of the most important things that have to be kept up to date.
Added for this article:If you don't have any of these programs installed just ignore the entry in this list:

1. Windows (better: all Microsoft software)
2. Security programs
3. ‏Firefox web browser 
4. Firefox add-ons
5. Java
6. Adobe Reader
7. Adobe Flash
8. Adobe Shockwave
9. Thunderbird email client
10. Thunderbird add-ons

My conclusion:

• It is very easy to keep Java up-to-date when you do that regularly anyway and are not stressed.
   
• At a time where you will be frustrated and impatient (you want to get back to what you were doing when you got interrupted!)  you are more likely to get tricked to inadvertently allow some unrelated gunk to get on your computer.

For the non-technical home user I install Java and admonish the user to keep it up-to-date.

Naturally it always is my customer's computer so in the end the customer has to decide if they want to live with or without Java. Uninstalling Java is easy:
Control Panel > Programs and features > Highlight Java > Right Click > Click Uninstall.

Please uninstall all versions of Java that you eventually see. Old out-of-date versions are a HUGE security risk!
