You need to put a try block around the line that invokes the
FileReader constructor. Then you need to put a catch block right
below the try block that catches the exception that the FileReader
constructor can throw.
Do you understand exceptions and how to work with them? The
FileReader constructor can throw an exception if it doesn't find the
file you specify. Because it can throw that exception, you need to
catch it and figure out what to do about it.
