Develop body of the method count(String[] arr) that takes an array of strings as argument, and prints how many times each digits '1'- '9' occurred in the strings. For example, if the method is called with following argument String[] arr = {"This is 2 of 2", "July 14", "cpsc1150"} Then the program should print: digit 1: 3 digit 2: 2 digit 4 : 1 digit 5:1 Since digit '1' occurs three times, '2' two times, '4' once, and '5' once. Read a list of words from a file (such as unsorted File.txt) and store them in a file (such as sorted List.txt) in an ascending order. To keep the problem simple, only consider words that include only alphabetical character or hyphen.
