Write a java program that will open a file, read each of the records from the file, use that data to populate a two dimensional array and write the sorted data out to a new text file.
Define a class named Munge which will do all the 'heavy lifting' in this program.
Build your project in NetBeans using the Run - Build Project, or Run - Clean and Build Project menu item.
From the dist directory you will execute your program from the command line with two filenames as arguments, input file name and output file name. For example:
java -jar lab5.jar ..\input.txt ..\output.txt
The input file will be a plain text file with one city name followed by a comma, followed by a single space, followed by the name of the province. The input file will have no more than 15 cities from one province so you can hard-code that value into your program when you are defining the size of your array. Some provinces may not exist in the data. The input file could be empty and your program should still run fine. Hand in all the input files you used to show how your data design helped to thoroughly test your software.
The output file will consist of the name of a province (assuming it has at least one city) followed by a colon, followed by a space a then a list of the cities from that province sorted alphabetically. The list of cities is comma separated. Notice the last city does not have a comma after it.
The provinces are sorted west to east followed by the three territories also from west to east.
The data must be stored in a two dimensional array of java Strings. Index 0 will represent the array of city Strings from British Columbia, index 1 will represent the array of city Strings from Alberta ... index 11 will represent the array of city Strings from Nunavut. By structuring it this way the provinces are already sorted.
When opening the files, catch the following exceptions: FileNotFoundException and SecurityException. Exit the program cleanly with an informative message to the user if these occur.
When reading records from the input file catch a NoSuchElementException and exit your program cleanly with an informative error message if this occurs.
When writing data to the output file catch a FormatterClosedException and exit your program cleanly with an informative error message if this occurs.
