Question

The board game scrabble works by assigning points to wooden tiles arranged in cells on a board. We'll simplify this considerably, and consider the following question. We begin with the letter-scoring scheme from Scrabble: a = 1, b = 3, c = 3, d = 2, ..., z = 10. Given a text file - a novel for example, what is the highest-(or a highest-) scoring line in the the file? In keeping with the Scrabble style, we'll add double and triple letter scores: any letter that falls at a line (String) position that's evenly divisible by 4 will have its score doubled; and any letter that falls at a line (String) position that's evenly divisible by 9 will have its score tripled. A letter at a position that's evenly divisible by 4 and 9 will have its score doubled, not tripled. All non-letters (e.g., space, comma, etc.) have score 0. Example: the line "now is the time" has a Scrabble score (by our rules) of 29. (Verify this with pencil and paper. Note that "n" is at position 0, which is a double letter score.) Your solution is in two classes: A driver class called LineScrabbleDriver, and a class called LineScrabble, which does the heavy lifting for the application. The LineScrabble class should extend Echo, in the standard way we've indicated (it could also extend the LineReader class from Chapter 11 of the text). Submit the code to these classes in the boxes below. Output: your program should report the (or a) highest scoring line in the input file, along with the score for that line. Tips: Make sure you master Chapter 10 of the text as a prelude to doing this problem. Here is a list from a to z of the letter scores from Scrabble: {1,3,3,2,1,4,2,4,1,8,5,1,3,1,1,3,10,1,1,1,1,4,4,8,4,10} Notice that this list is in proper format for copying and pasting directly into your program as an int array. It's far easier to convert lines of text to lowercase before processing. You MUST use a try-catch harness in driver class. You MUST comment every method with a one line description of the job that method does, and your description must be placed just below the method header line. Two sample files are provided: sampletext.txt is silly but useful, and HeartOfDarkness.txt is the famous novella by Joseph Conrad. Some sample output: enter file name sampletext.txt winner: "and aid. their. party?" score: 40 ------------------------------- enter file name HeartOfDarkness.txt winner: "plenty time. i can manage. you take kurtz away quick--quick--i tell" score: 192

Explanation / Answer

import java.util.*; import java.io.*; public class ScrabbleDriver{ public static void main(String args[]) { try{ Scanner s = new Scanner(System.in); System.out.println("enter file name, then word size"); String f = s.next(); int size = s.nextInt(); Scrabble scrab = new Scrabble(f,size); scrab.readLines(); scrab.reportWinner(); } catch(Exception e) {System.out.println(e);} } }
