File Processing Write a static method named reportBlankLines that accepts a Scanner containing an input file as a parameter and that outputs the line numbers of any blank lines and that reports the total number of blank lines in the file. For example, given the following input file: Remember that a file can have blank lines like the one below: A blank line: is read as a String of length 0 by Scanner Your method should print the following output line 4 is blank line 6 is blank line 9 is blank total blank lines = 3 Notice that each blank line produces a line of output and that there is a final line of output reporting the total number of blank lines. Also notice that lines are numbered starting with 1 (first line is line 1, second line is line 2, and so on)
