No, Java is needed only if you run programs that are written in Java. The majority of computer users today could disable Java and never know the difference.

Probably not, unless you run a virus written in Java.
No. Java is not an operating system, it is a programming language.
You only need one version of the JRE to run a Java application.
you can if you upload the right operating system needed to run that PC game or the elements needed.
I don't think it is required, but it is used a lot. You need Java to run many applications you may download, various online games, and I believe even YouTube & Myspace use Java.
Not really any. Java is required, and therefore your computer should be able to run it. I would recommend atleast 4gb of RAM, and a decent videocard to render pixels, along with a i5 Intel core :)
No, Java script is not needed to play poptropica.
If your meaning PC, Mac and Android the only computers I know it works on is PC and Mac...not sure about Android. Basically anything computer that can run Java.
There are two main things you can download for Java: the Java Runtime Environment (JRE) and the Java Development Kit (JDK). The JRE is used by those who wish only to run Java programs. In order to do this it uses the Java Virtual Machine (JVM) to run Java bytecode. The JDK is used by developers and contains both the JRE and the programs and libraries needed to compile and run Java programs. Simple summary: The JDK contains the JRE which contains the JVM.
You never really need a Java application on your PC. If you don't want them, don't install them.
No; lots of programs run without Java. You only need the Java runtime to run programs specifically designed with Java technology.
