Why do I see many exceptions for one missing file on the stack trace ?

My guess is, where ever that file or methof is being called , all of them will throw exceptions.

So, where do I find the root exception, first one which is thrown OR the last one ?

In the above stack trace, "java.io.FileNotFoundException: c:\temp\pw.txt (The system cannot find the file specified)" is the root cause (Assuming there is only one error which causes code to fail) ? Is the first one cause of failure whch then cascades failure of other methods ?

Thanks

There is only one exception here. What you are seeing is the stack trace - the listing of every method on the execution stack (I think that's the right terminology).
