Homework 2 instructions

Create a Java project in Maven.

Read from an input file called "input.txt."  I have supplied one test file, but I may run it against other files that meet the specification.  I suggest that you make a few very short files with just two or three lines of data so that you can check your work.

The file input.txt contains lines of data.  In the sample file provided, The lines have the following characteristics

Lines are "colon delimited"
Valid lines contain two fields.  (Invalid lines should be ignored when processing)
The number of lines is unknown in advance
Dates are in "standard" US format of month/day/year
If there are exactly two dates on a line, those dates may be assumed to be valid dates.
For each line of text in the file:

Split the line of text on the tab.
If there are exactly two fields on the line, process the line.  Ignore lines with other than two fields.
Use a method to split the date into the month, day, and year fields.  The method should return an instance of the LocalDate class.
Use a method to print the dates in order.  They should be printed on the same line with a \t character between.  If the dates match exactly, then the order does not matter.  The earlier date should be printed first, and the later date printed last.
At the end of the program print the number of date-pairs processed.



Text for an input.txt file is provided at the end of this assignment.  You may test against this file, but I suggest that you also test against other data.  You may want to make a file with only a handful of lines of data to help you check your results.



Pseudocode

main()
   Scanner input = openFile("input.txt)
   int pairsProcessed
   pairsProcessed = processDates(input)
   close input
   print pairsProcessed

processDates(Scanner input)
    int n = 0;
    while input has more lines
          line = input.nextLine()
          String[] dates = line.split(":");
           if (dates.length == 2)
                n++
                LocalDate a = makeDate(dates[0]);
                LocalDate b = makeDate(dates[1]);
                if( a is before b)   Note that (a < b) will not work!
                     print a b
                 else
                      print b a
      return n;

makeDates(String s)
      Localdate date = null;
      String[] parts = split s on the "/" character
      int month = Integer.parseInt(parts[0])
      int day = ...
      int year=...
      date = LocalDate.of( ... )
      return date
