String pearDataFile is read from input. The try block opens a file named pearDataFile for output. Four integers are read from input, and each integer is written into the file. Write the finally block to perform the following tasks, if the output file is open:

Write to the file "Number of valid values read: $",$ followed by pearCount and a newline.

Ex: If the input is pearoutput. txt $25,3837,29,$ then pearOutput.txt contains:

$25$

$38$

$37$

$29$

Number of valid values read: $4$

Ex: If the input is data. txt reject $38,37,29,$ then data.txt contains:

Number of valid values read: $0$

Ex: If the input is $/f$ ail. $txt,$ then the output is:

Error!

Note: Data output to a file may be lost if the file is not closed.
