String widthDataFile is read from input. The try block opens a file named widthDataFile for output. Two floating-point numbers are read from input, and each floating-point number is written into the file. Write the finally block to perform the following tasks, if the output file is open: 1. Write to the file "Number of input values read: ", followed by numValues Read and a newline. 2. If numValuesRead is greater than zero, write to the file "Last value is: ", followed by widthLast and a newline. 3. Close the file. Ex: If the input is width.txt 12.0 11.0, then width.txt contains: 12.0 11.0 Number of input values read: 2 Last value is: 11.0 Ex: If the input is widthFile.txt invalid 11.0, then widthFile.txt contains: Number of input values read: 0 Ex: If the input is /nowhere.txt, then the output is: Error! Note: Data output to a file may be lost if the file is not closed. 1 import java.util.Scanner; 2 import java.io.FileOutputStream; 3 import java.io.Printwriter; 4 5 public class WriteLastWidthFile { 6 7 8 9 10 11 12 13 14 15 16 17 public static void main(String[] args) { Scanner scnr = new Scanner(System.in); Printwriter foutWriter = null; String widthDataFile; double valueRead; int numValues Read = 0; double widthLast = 0.0; widthDataFile = scnr.next(); try { foutWriter = new Printwriter(new FileOutputStream(widthDataFile));

New JAVA code can only be added between lines 27 and 29. As seen in image.
![String widthDataFile is read from input. The try block opens a file named widthDataFile for output. Two floating-point numbers are
read from input, and each floating-point number is written into the file. Write the finally block to perform the following tasks, if the
output file is open:
1. Write to the file "Number of input values read: ", followed by numValues Read and a newline.
2. If numValuesRead is greater than zero, write to the file "Last value is: ", followed by widthLast and a newline.
3. Close the file.
Ex: If the input is width.txt 12.0 11.0, then width.txt contains:
12.0
11.0
Number of input values read: 2
Last value is: 11.0
Ex: If the input is widthFile.txt invalid 11.0, then widthFile.txt contains:
Number of input values read: 0
Ex: If the input is /nowhere.txt, then the output is:
Error!
Note: Data output to a file may be lost if the file is not closed.
