I have an assignment to find least used icons on desktop in Windows.
I need to code using JAVA. Which property of the File object in JAVA will be useful?
I have started analysis on it. A help will be much appreciated.
Have you checked out the File API? File#lastAccessTime is probably what you are looking for. Keep in mind that this only works in Java 7.
As for FREQUENCY of use, I do not think Windows keeps any data per-file... So you will have to rely on the last time of modification, possibly vs time of creation. The Java function you will need to rely on is lastModified(), eg
file_list[i].lastModified()

I'm writing an application in java. In order to work my code properly, I want to check whether several software are installed. (This should be done in the java code itself.)
How can I do that?
This is a Linux system.
There are similar questions, but not exactly what I want.
Check if a program is installed on a linux machine from a java applet
There is no universal way of doing it.
You can use one of following approaches
Use java bindings for particular package manager for your platform if they exist.
Use one of the system tools like locate, whereis, etc. (which you didn't like)
Implement your own installed package detection, according to your requirements

I've searched in Internet about burning CD/DVD that can work either in Linux and Windows. but unfortunately, I couldn't find a good solution.
Somebody suggested me, use commands line that related to Operating system. but I think it'd better write a good code that be able to use everywhere.
All my needs are described below:
get list of accessible driver name
get list of writer speed that any driver can do.
burn CD/DVD
So, If you can solve this problem, help me.
Thank you

I am kind of stuck in a dilemma. I want to create a tool that would generate code on the fly by taking various parameters from the user. The codes have a few similar features and few things need to be altered from one code to other to other. Based on the parameters, I can have 15 different codes. Till now I have been using file handling in Java to implement this as I have the created codes in different files but this doesn't seem to be a great method. Can you please suggest something that is better than this??
Since Java 1.6 you can compile in memory whatever you want. Take a look at this code:
http://code.google.com/p/cachos/source/browse/trunk/cachos/src/com/peyrona/cachos/InMemoryCompiler.java
http://code.google.com/p/cachos/source/browse/trunk/cachos/src/com/peyrona/cachos/InMemoryExecutor.java
In this example you can see how you can compile a source code stored in a String in memory, without using the disk.

I think this is what you're looking for.

I want a program to get information about RAM
How can i do that?
There's a couple of memory-related methods in the Runtime class, but note that they only give information about the amount of memory available to (or used by) the JVM, not the hardware it runs on.
Generally, Java is the wrong language to do this kind of thing, since it requires access to OS APIs that Java does not provide.
Most of the information you need will be contained in the Runtime class. Have a look at the link. It should be straightforward. If you run into problems with it, I will try to help you out further.

I think of doing something like a file cleaner for Windows with Java just for fun, I want it to be able to clean the temp files, caches... etc for the major browsers opera, ie, firefox.
I'm basically looking for some guidance to where to start my research, what are some good reads and basically what kind of libraries will I have to use (if any).
I think you should take a look at bleachbit. It's written in python, but the actions should be easily converted to java. But then again, why not just use bleachbit itself?
