String avocadoDataName is read from input. The try block opens a file named avocadoDataName to read an integer into dataValue.

Complete the try$-$with$-$resources statement to declare a Scanner object named avocadoScanner with a FilelnputStream constructed with string avocadoDataName.

Ex$.$ If the input is avocado$2.$txt$,$ then the output is:

Value read from avocado$2.$txt: $29$

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

Error opening file: invalid.txt

avocado$2.$txt
