Java programming

Implement a class Files that provides 2 file transformation methods: sortFile and spellDigits. sortFile sorts the words and lines of a file lexicographically, and spellDigits replaces each occurrence of a digit (0-9) in a file with the word (in all caps) that spells out that digit, e.g., ZERO, ONE, TWO, etc.

Template:

public class Files { /** * Sorts the words in each line of a file lexicographically, then sorts the * lines lexicographically, and writes the result back to the original file with * a space between each word and no space between each line. Ignores blank lines * and does not write them to the revised file. * * @param fileName name of the input file */ public static void sortFile(String fileName) { // FILL IN } /** * Replaces each occurrence of a digit (0-9) in a file with the word (in all * caps) that spells out that digit, e.g., ZERO, ONE, TWO, etc. * * @param fileName name of the input file */ public static void spellDigits(String fileName) { // FILL IN } }

Sample files:

Down, down, down. There was nothing else to do, so Alice soon began talking again. 'Dinah'll miss me very much to-night, I should think!' (Dinah was the cat.)

Alice was 12 years old.

Output example:

'Dinah'll I again. me miss much should talking think!' to-night, very (Dinah cat.) the was 12 Alice old. was years Alice Down, There began do, down, down. else nothing so soon to was

Sample file:

1 Michael 462085 2.2506 Jessica 302962 1.5436 2 Christopher 361250 1.7595 Ashley 301702 1.5372 3 Matthew 351477 1.7119 Emily 237133 1.2082 4 Joshua 328955 1.6022 Sarah 224000 1.1413 5 Jacob 298016 1.4515 Samantha 223913 1.1408 6 Nicholas 275222 1.3405 Amanda 190901 0.9726 7 Andrew 272600 1.3277 Brittany 190779 0.9720 8 Daniel 271734 1.3235 Elizabeth 172383 0.8783 9 Tyler 262218 1.2771 Taylor 168977 0.8609 10 Joseph 260365 1.2681 Megan 160312 0.8609
