Hey guys!!!
I know these simulations are too much but....
still another one and I am havin some problems with that///
I have to create a file system simulation that has to understand these commands:
cr a - create a new file named a, size ==0;
rm a - remove file a
op a - open file a
cl a - close file a
rd a - read file a
wr a - write file a
cp a b - copy file a to file b

I have to use:
DIRECTORY IMPLEMENTATITON
LINEAR LIST
ALLOCATION METHODS
CONTIGUOUS ALLOCATION
LINKED ALLOCATION(FAT)
FREE - SPACE MANAGEMENT
FREE-SPACE LIST
PROTECTION AND SECURITY

I HAVE TO USE AN ARRAY OF BYTES

P.S PLEASE GIVE ME SOME IDEA... I KNOW HOW TO DO SOME OF THE STAFF BUT I AM NOT SURE IF THIS IS THE RIGHT WAY TO APPROACH IT
LIKE INSTEAD OF ARRAY OF BYTES I WILL CREATE A BYTE BUFFER TO ALLOCATE THE SPACE...
BUT I HAVE NO IDEA HOW TO ALLOCATE THE SPACE ONCE THE FILE IS CREATED!!!!

Open up a text editor and get started.

Then I tried to emulate file system I had no idea how to do that. BoxedApp SDK helped very much.
(But that project I wrote in C++ )

I don't understand the second half of your explanation, so hopefully this is useful to you. File class: http://java.sun.com/javase/6/docs/api/java/io/File.html

For example you can easily create a new file using the createNewFile method. There are plenty of useful methods in there.

And I am sure the guy has already solved his problem 3 years ago, Talk about speedy replies !!!!

Oh ****, what a waste of time. I didn't even realize that this noob had upped an ancient thread.
