Feel free to edit and improve this answer; I needed an answer myself, and found the question but no answer to date, and so am giving it a whirl:
When I hear "Java" I'm thinking of a JRE or Java Runtime Environment. (It's not the same as JavaScript, however, which our present question does not touch.) JRE supports (a) the writing of applications to run on several Operating Systems; and (b) applications that need Java in order to run. So, if you don't have Java, but need either or both to write or use applications that are supported by Java, why then it seems you'd need to install Java. On the other hand, if you already have Java, and are not sure whether to uninstall it, you will want to find out whether you need to write or use such applications. The first should be easy: just ask yourself if you need to write such programs The second... here's where I'd love some help editing the answer!
Temporarily and tentatively, you could (a) right click each application you suspect might use Java, choose "properties", and see when the program was last used. Some kinds of programs that use Java are those that show 3-D images from various angles, those that move images around a lot. Example, architectural design programs, and many games. (b) Perhaps also, you can poke around in the Java files, and see if you can find out when Java was last used. In any case, you can (a) set a "Recovery Point" (in Windows at least), and then use "Add/Delete Programs" to uninstall your Java program(s), and see if everything you usually use is still working. If not, you undo the change by restoring that Recovery Point. (I'm supposing you are at least moderately computer savvy and know what you're doing, or have a friend who is.)
Part of the decision depends on the benefits and drawbacks of having Java. Its benefits are many (see the web-site of the Java folks). Its drawbacks are its huge size and consequent use of much memory and much time for installing and for updating. (It was the huge updates that got me to find and ask the same Question we're editing now.)
The java.lang package in Java is automatically imported for you.
Yes, it is possible to write a keylogger in Java, but you would need to use the Java Native Interface to do so.
Most browsers nowaday are compatible with Java. In some cases you need to install Java as a plug-in. In this case, the browser will usually ask you automatically, whether you want to install Java, as soon as it is needed - i.e., as soon as you access a Web page that requires Java support.
Yes. Java 1.5 or later (1.6 Recommended) http://www.frostwire.com/?id=downloads
every thing for our small stomach...
Any program written for the Java technology needs Java. Any program NOT written for Java DOESN'T need it.
you need java 1.5 to run mindcraft
You need java
Yes, Java is the platform Minecraft runs on. Java is free for download.
Programs that are specifically designed with Java require a Java runtime to work on a computer. (In the case of Java, the runtime is called "Java Virtual Machine".) If you have any such program, you need to have Java.

Hi You should read Java API , there is every thing that you need.
In general, not. The browser will work without Java; some individual sites that require Java will NOT work.
Java script coding is computer coding, many things require Java, and you need to have Java enabled to view these types of programs.
You never really need a Java application on your PC. If you don't want them, don't install them.
