Thanks ! I needed it for my app here

My pen-drive has no write-protect switch like the good old floppies. I wanted to make it protected so that those worms and viruses dont infect it when i put it in other computers.
So, to make it write-protected, i made a java program that generates a dummy file. We can see the empty space of the pen drive and create a dummy of that size and put it in the pen drive.

Minor problem with code - You fill the drive with a dummy file. Even after doing that there is some small space left in the drive. I have to run the code again and make a dummy of that size. Then, the pen drive is completely filled.

Can anyone add these features for me ?

(1) Detect pen-drive empty space and generate a file of the exact size in one attempt.
(2) make it GUI based.

Anything else you can think of (issues, suggestions etc) ?

Here is the code, it is console based :

I can use this to create an 8GB file within a second. The file will use 0 to fill the file.

Thanks ! I tried that and it works well.

If you can think of a meaningful (i.e. non-trivial) topic in Java 7, let me know

When you make the new edition, please add some small coding problems or toy app questions after every chapter to test and practice the concepts learned.
Thanks again for making such a nice book ! If we did not have people like you, learning would be a torture.

Random characters. Does the code change according to the data that this file may contain ? Please give examples.

Please suggest some ways to make java code which generates a file of size entered by the user. The range can be from a few bytes (bits also possible ???) to many megabytes.

Dont worry. Sometimes, it takes more than a month. I took about 3 months to prepare. Some guys take 2 weeks and some take much more. Practice a lot of sample tests,
try the questions in the book - ocp programmer exams (kathy and bert) , write a LOT of code.

Good luck.

(1)Can you suggest some beginner level books for Linux ?

(2)Which flavour of linux would be best for a beginner (i have ubuntu, but i rarely use it) ?

(3)Can i experience unix-like interface on ubuntu linux (which is GUI based) -> the black screens and only typing commands ?

I was suggested unix here

Without knowledge of development using the Unix command line, you put yourself well behind the eight ball when it comes to job prospects.

Which one of the two OS would be better in terms of :
(1) Quantity and quality of learning resources available.
(2) Need in industry

Please suggest some good beginner level books for unix and linux.

What does that mean ? and why is the knowledge of unix so critical to success ?

To add to that, see this link.

Deviating from the main topic -

It looks like the "government" is simply buying time, hoping that anna will fall ill and protesters will get tired and go back home. I am only hoping that this will not happen. Most of the people have jobs to do, families to take care of etc. I wonder if people can keep the pressure high enough for as long as it takes.

Corrupt people tend to respond only to force like the one we see in other parts of the world.
