COSC 237 Dierbach Spring 2022 COSC 237 Dierbach Spring 2022 PROGRAM 2 Word Count Program (Object-Oriented Version) 50 pts. DESCRIPTION For this assignment, you are to redesign the imperative version of the Word Count program to use an objectoriented design. You must use the skeleton code given below. The output of the program should be the same as in Program 1. Word Occurrences lake 14 he 42 they 31 person 8 etc. You are to test your completed program using your own test files. Such test files can be created using notepad, or any simple editor that does not add word processing characters. The name of the data file should be .txt, and you should enter the full file name including the .txt extension when running the program. The text file should be placed in the same directory as the source file. WHAT TO TURN IN You are to submit to Blackboard:  the source code only of your program (.java files) NOTES (1) Your program should work for any text file including any characters. (2) Words differing only in upper/lower case should be considered the same word (e.g., The and the). (3) You are encouraged to use the debugger in Netbeans for debugging your program. (4) Make sure that you test your program well. I will test all programs with my own test files. Skeleton Code Provided on the following pages //=========================================================================== // WORD COUNT PROGRAM (Object-Oriented Design) //=========================================================================== // This program will input any text file and output a table of word counts // containing each word in the document and the number of times that each // word appears.
