String fileName is read from input. The try block opens a file named fileName to read a floating$-$point number into dataValue.

Complete the try$-$with$-$resources statement to declare a Scanner object named fileScanner with a FileInputStream constructed with string fileName.

Ex: If the input is width$1.$txt$,$ then the output is:

Value read from width$1.$txt: $3\mathrm{.}4$

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

Cannot open file: nosuchfile.txt
