 Q: Does anybody know a convenient way to pause the dos program execution

Can anyone please explain clearly how BufferedReader works and how to use it to
get input from a keyboard?
 Q: Can anyone please explain clearly how BufferedReader works and how to
use it to get input from a keyboard?
Answer:  BufferedReader is a filter reader class. 
That is, it wraps another reader and reading from it is like reading from the reader it
wraps, except that it changes something. In the case of BufferedReader, it reads in
large chunks and then you can retrieve its data in smaller bits. To use it to read from
System.in, you first need a reader to wrap. You can bridge from an input stream
(which System.in is) to a reader by using an InputStreamReader.
Then wrap that in a BufferedReader as follows:
   BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
Now you can call methods of BufferedReader to read from standard input. Generally,
you create a BufferedReader to be able to call the readLine() method. That isn t
BufferedReader s main intended use    the main intended use is performance    but
you don t generally care too awfully much about performance of reads from the
console. So call readLine to get a line of input, which will be null on end of stream
(user presses Ctrl D on UNIX or a file was redirected in and is done).

 How do I encode the value of a variable of type long (or int) into bytes? And how
do I restore the original value of the long (or int) variable back
How do I encode the value of a variable of type long (or int) into bytes such that the
number of bytes used will always be the same, say 4 bytes?
