Write a Java program that reads each line of an input file called data.txt that consists of a keyword followed by a sequence of numbers separated by commas and save it in arrayList. Then for each row in the arrayList check if the keyword is UP, the numbers are sorted in increasing order, if the key word is DOWN; the numbers are sorted in decreasing order. The sorted sequence of numbers is saved in sorted.txt. For example, if the data.txt contains UP: 25 35 30 40 30 DOWN : 20 30 25 25 DOWN: 35 45 40 15 16 18 The file sorted.txt will contain 25 30 30 35 40 30 25 25 20 45 40 35 18 16 15 Create class Sort to perform all sorting operations. The class also responsible of checking the validity of input file content. All input file records must follow the following format UP/down set of numbers
