Bizzare Scrabble Project
The board game scrabble works by assigning points to wooden tiles arranged in cells on a board. It's described here: Scrabble.
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. (Important: 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. Submit the code to these classes in the boxes below.
Echo code:
import java.util.Scanner;
import java.io.*;
public class Echo{
private String fileName; // external file name
private Scanner scan; // Scanner object for reading from external file
public Echo(String f) throws IOException
{
fileName = f;
scan = new Scanner(new FileReader(fileName));
}
public String getFileName(){
return fileName;
}
public void readLines(){ // reads lines, hands each to processLine
while(scan.hasNext()){
processLine(scan.nextLine());
}
scan.close();
}
public void processLine(String line){ // does the real processing work
System.out.println(line);
}
}
Project requirments:
You MUST use a try-catch harness in the 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.
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.
Two sample files are provided: sampletext.txt is silly but useful, and HeartOfDarkness.txt is the famous novella by Joseph Conrad.
Explanation / Answer
Below is your code
Echo.java
public class Echo {
private String fileName; // external file name
private Scanner scan; // Scanner object for reading from external file
public Echo(String f) throws IOException {
fileName = f;
scan = new Scanner(new FileReader(fileName));
}
public String getFileName() {
return fileName;
}
public void readLines() { // reads lines, hands each to processLine
while (scan.hasNext()) {
processLine(scan.nextLine());
}
scan.close();
}
public void processLine(String line) { // does the real processing work
System.out.println(line);
}
}
LineScrabble.java
public class LineScrabble extends Echo {
int max = 0;
String bestLine = "";
public LineScrabble(String f) throws IOException {
super(f);
}
int[] scrabbles = { 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 };
public void processLine(String s) {
s.toLowerCase();
int score = 0;
for (int i = 0; i < s.length(); i++) {
int w = (int) (s.charAt(i) - 97);
if (w >= 0 && w <= 25) {
if (i == 0) {
score += 2 * scrabbles[w];
} else if (i % 4 == 0 && i % 9 == 0) {
score += 2 * scrabbles[w];
} else if (i % 9 == 0) {
score += 3 * scrabbles[w];
} else if (i % 4 == 0) {
score += 2 * scrabbles[w];
}
}
}
if (score > max) {
max = score;
bestLine = s;
}
}
public void results() {
System.out.println("Winning score: " + max);
System.out.println("Winning line: " + bestLine);
}
}
LineScrabbleDriver.java
public class LineScrabbleDriver {
public static void main(String args[]) throws IOException {
System.out.println("Enter file name: ");
Scanner scan = new Scanner(System.in);
// gets the filename from the user
String fileName = scan.nextLine();
// creats an object for LineScrable class and passes the
// filename as parameter
LineScrabble ls = new LineScrabble(fileName);
// reads each line from the file
// and process it
ls.readLines();
// displays the winner
ls.results();
}
}
