问题要求 acm 图形程序读取这样的 txt 文件：
R
FUN
SALES
RECEIPT
MERE@FARM
DOVE@@@RAIL
MORE@@@@@DRAW
HARD@@@TIED
LION@SAND
EVENING
EVADE
ARE
D
并做一个填字游戏，字母上有空白方块，“@”上有黑色方块，空白处什么也没有。该问题还要求“如果方块位于跨越、向下或两者的单词的开头，则方块应包含一个在拼图中按顺序分配的数字。”
我有方形绘图工作，但我坚持正确绘制数字。我检测零空间和黑色方块的方式有问题。有人可以告诉我我做错了什么吗？
这是代码：
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 for square x and y dimensions
private int y = 0;
public void makeCrosswordPuzzle(String fileName) {
BufferedReader rd;
int y = 0; // y value for the square being added during that loop. increments by sqCon after every line
int wordNumber = 1; // variable for numbers added to certain boxes. increments every time the program adds a number
try {
rd = new BufferedReader(new FileReader(fileName));
String line = rd.readLine(); //reads one line of the text document at a time and makes it a string
while (line != null) {
int x = 0;
for (int i = 0; i < line.length(); i++) {
char lineChar = line.charAt(i);// the character being examined for each loop
GRect whiteSq = new GRect(sqCon,sqCon); //GRect for blank squares
GRect blackSq = new GRect(sqCon,sqCon);//GRect for black squares
blackSq.setFilled(true);
blackSq.setFillColor(Color.BLACK);
if (lineChar == '@'){
add (blackSq,x,y);
}
if (Character.isLetter(lineChar)) {
add (whiteSq, x, y);
// if the element above or to the left of the current focus is null or blackSq, place the number and then 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);
}
}
}
编辑添加：
我将您的代码复制到我的 Eclipse 并运行它。这是结果。
你在上半部分做得很好，但你错过了下半部分的倒数。
这是相同的代码，重新格式化以便更容易阅读。
