String daikonDataName is read from input. The try block opens a file named daikonDataName using a try$-$with$-$resources statement, and reads an integer from the file into dataValue.

Write an exception handler to catch a FileNotFoundException and assign errorFound with true.

Ex: If the input is daikon$3.$txt$,$ then the output is:

Value read from daikon$3.$txt: $46$

Success: File processed

Ex: If the input is nofile.txt$,$ then the output is:

nofile.txt: File not available
