Problem
1. Why doesn't the read File method catch any exceptions?
2. Consider the try/finally statement in the read File method. Why was the in variable declared outside the try block?
3. Suppose the user specifies a file that exists and is empty. Trace the flow of execution in the Data Analyzer program.
4. Why didn't the read Data method call has Next Int/ has Next Double to ensure that the No Such Element Exception is not thrown?
