File Input and Output

I ran the tasks on a MacBook Pro, and got these results:

Task	Time
1.) Copy file one byte at a time.	0.092714 sec
2.) Copy a file using a byte array of size 8 Bytes	0.013946 sec
3.) Copy a file using a byte array of size 32 Bytes	0.003638 sec
4.) Copy a file using a byte array of size 512 Bytes	0.000368 sec
5.) Copy a file using BufferedReader and PrintWriter	0.004953 sec

Explanation of Results

4th task is the fastest run time because 4th task can copy many file more than 1st, 2nd, 3rd and 5th task at a time. The first task is the slowest task because it can copy file just only one byte at a time. In case of 5th task, it's need a little time to covert from byte to String. For a file using a byte array will faster if you increase size of a byte array because you reserved memory location to copy a file.
