Upon looking around on my PC at documents and programs that I apparently downloaded, one of the ways that popped up to surf the
net is âJava Sunâ. I have no idea where that came from. I use explorer and Firefox. Is this âJava Sunâ dangerous? Any idea how I
got it on my PC?
One clarification, itâs âJavaâ, produced by a company by the name of âSunâ Microsystems.
Itâs not dangerous, in and of itself, but like any programming language or internet tool it can of course be used for good or
evil.

Second clarification: âJavaâ and âJavascriptâ are unrelated.
Iâd call it a poor naming choice of âMicrosoft-eanâ proportions. Microsoft is known for itâs confusing names such as âOutlookâ
and âOutlook Expressâ (which have no relationship to each other), or the current mess that is âHotmailâ, âWindows Live Mailâ,
âWindows Live Hotmailâ and âWindows Mailâ (three different things with four different names).
The fact that Java and Javascript are unrelated and yet have similar names is unfortunate.
Java is a programming language. All that really means to most folks is simply that when you run an application, the developer
who wrote it might have been using Java to create the program.
Programs written in Java are transformed or âcompiledâ into an intermediate form that when run is interpreted by whatâs called a
âvirtual machineâ or VM. That intermediate form is not machine or platform specific â meaning that as long as thereâs a Java
virtual machine available for the platform youâre running on, a program written in Java may be able to run on it. In fact, one of
Javaâs mottos is âWrite Once, Run Anywhereâ. (Of course programmers certainly can still write Java programs that work on only
specific platforms.) Java Virtual Machines are available for most popular platforms including Windows, Mac and Linux.
Because of its ability to be platform in ependent, Java is an occasionally popular language for web-based applications or
âappletsâ. When you visit a web site that uses a Java applet, you may be prompted to download and install the Java VM, if you donât
already have it, and then the web application can run.
Visiting a web site that uses a Java applet is probably how you ended up with Java on your machine.
One of the items that occasionally surprises people is that Sunâs implementation of the Java VM will automatically update it self,
much like Windows itself. Suddenly a Sun Java icon might appear in your taskbarâs notification area telling you that a new version
is available, or that a new version has been downloaded and installed.
The bottom line is simply that by virtue of having done some surfing on the web you may have downloaded and installed Java.
Thatâs typical, and nothing to be worried about. Similarly, if you periodically see update notifications for the Java VM, that too
is to be expected.
Itâs amazing how many sites depend on Java to run. You can disable those updates if you like though. :)
Java usually puts an icon in your âcontrol panelâ, mine looks like a coffee cup, this is where you can change the settings including disabling automatice updates.
Do I need Java, I have about 6 application of It, can I delete some of them after it download the new version
I need to know, as Anita did if I can delete the earlier versions of Java off my system, and just keep the most recent update. Thank you.
I tried to uninstall java but it wasnât included in the list so I searched for any java files and deleted themâŠnow Iâm having more trouble than beforeâŠcan you tell me what to do? I havenât emptied my recycle file yetâŠshould I restore all the java files?
