InputStream is an abstract class.When we System.in , what is the class that extends this InputStream class to give implementations to the abstract class.

I believe that System.in is a machine dependent (possibly native method) implementation of InputStream.

The combination of the classes BufferedReader and InputStreamReader will be practical as was stated above in many cases. If you would like byte-wise reading with the line separator (e.g. '
') explicit, then the method read() of the class BufferedInputStream will also be used.

If you want to be able to read indivdual characters:

InputStreamReader in = new InputStreamReader(System.in);

If you want to be able to read Strings and characters:

BufferedReader in
= new BufferedReader(new InputStreamReader(System.in));
