file system simulation in java

this project requires you to build a simulation of a file system to store text objects.

Your file system simulation must understand the following commands (all filenames are single character):

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

You have to implement the file system structure using the following recommendations:

Directory implementation.

1. Linear list (utilizing a hash table)

Allocation methods.

1. Contiguous allocation.

2. Linked allocation (file allocation table FAT)

Free-space management.

1. Free-space list.

Protection/security mechanism.

1. Your choice.

The intent of this project is that you should have to face and solve several of the problems faced by designers of file systems.

However, several simplifications are necessary to achieve a realistic project:

1. The "disk" will be an array of bytes of fixed size (about 500k). You may define a class that is an array of fixed size

blocks representing disk sectors.

2. All files will be text objects (strings with embedded control characters).

3. You will need a way to drive the file system, i.e. to invoke the methods representing its interface. You should be able to

create, delete, read and write files, but when the end of the disk is reached you may terminate your program.
