I'm attempting to read through a given text file and sort through it using pattern matching based on address given, When reading through the file though im getting a weird NumberFormatException error on the 45 5th ave lines and im not understanding what this error means and why its occuring from this line but not from another like 22 broadway which prints out just fine. Also should i be using scanner for this instead or is bufferedreader okay to be using for this project and how could nonpattern matching lines be stored to be outputted later in the output as addresses that didnt match?
TEXT FILE
123-ABC-4567, 15 W. 15th St., 50.1
456-BGT-9876,22 Broadway,24

6578-FGH-9845 ,,45 5th Ave, 12.2, A crucial part of your code is splitting by , and you accidentally have 2 commas in one place. This causes it to skip a section and try to format it as a number; making it throw the exception. The corrected line would look like 6578-FGH-9845, 45 5th Ave, 12.2
