Keep in mind that readLine can return null, so before calling input.equals you need to check for input being null.

In what cases can it return null? Im testing this from my eclipse IDE and not able to simulate a case when it can return a null so that it can fail.

From the javadocs:
A String containing the contents of the line, not including any line-termination characters, or null if the end of the stream has been reached.

thanks for replying, i am unable to solve the problem as pallavi said i have used input.equals("") but this is not the only one condition in which it needs to work. If the user gives the input as a space or a tab or 2 or mare spaces or 2 or more tabs it does'nt work. I have also used the trim() method i.e input.trim() also insane. Some body please help me out
