Numbering A Crossword Java ACM Graphics -
the problem asks acm graphics program reads txt file this:
r fun sales receipt mere@farm dove@@@rail more@@@@@draw hard@@@tied lion@sand evening evade d and makes crossword puzzle, blank squares on letters, black squares on '@', , nothing on empty spaces. problem asks "if square @ beginning of word running across, down, or both, square should contain number assigned sequentially through puzzle."
i have square drawing working, i'm stuck on drawing numbers correctly. there wrong how i'm detecting null space , black squares. can tell me i'm doing wrong, please?
here code:
import acm.program.*; import java.io.*; import java.util.*; import acm.graphics.*; import java.awt.*; public class crossword extends graphicsprogram { public void run() { string filename = "crosswordfile.txt"; makecrosswordpuzzle(filename); } private static final int sqcon = 15; // constant square x , y dimensions private int y = 0; public void makecrosswordpuzzle(string filename) { bufferedreader rd; int y = 0; // y value square being added during loop. increments sqcon after every line int wordnumber = 1; // variable numbers added boxes. increments every time program adds number try { rd = new bufferedreader(new filereader(filename)); string line = rd.readline(); //reads 1 line of text document @ time , makes string while (line != null) { int x = 0; (int = 0; < line.length(); i++) { char linechar = line.charat(i);// character being examined each loop grect whitesq = new grect(sqcon,sqcon); //grect blank squares grect blacksq = new grect(sqcon,sqcon);//grect black squares blacksq.setfilled(true); blacksq.setfillcolor(color.black); if (linechar == '@'){ add (blacksq,x,y); } if (character.isletter(linechar)) { add (whitesq, x, y); // if element above or left of current focus null or blacksq, place number , increment wordnumber gobject above = getelementat(x+sqcon/2,y-sqcon/2); gobject left = getelementat(x-sqcon/2, y+sqcon/2); glabel wordnumberlabel = new glabel(integer.tostring(wordnumber)); if (above == null || left == null || above == blacksq || left == blacksq) { add(wordnumberlabel,x,y+sqcon); wordnumber++; } } x += sqcon; } line = rd.readline(); y += sqcon; } rd.close(); } catch (ioexception e) { throw new errorexception(e); } } }
edited add:
i copied code on eclipse , ran it. here's result.
you did fine on upper half, missed down numbers on lower half.
here's same code, reformatted it's easier read.

i followed advice of own comment. created crossword puzzle answer, numbered crossword puzzle answer, , drew crossword puzzle answer.
here's applet result:
i kept list of crossword puzzle cells. way, determine length , width of puzzle number of characters on row , number of rows of input text file. didn't have hard code dimensions.
for each crossword cell, kept track of whether or not letter, , whether or not dark space.
when determining put numbers, followed 2 rules.
an across number placed cell left of cell empty or dark, , there 3 or more letters across.
a down number placed cell above cell empty or dark, there 3 or more letters down, , there no across number.
you can see in code had debug printing crossword puzzle clue numbering correct. broke process many methods keep each method simple possible.
finally, drew crossword puzzle answer information in list.
here's code:
