在java中将ascii字符的txt文件读入2d数组

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class ReadAsciiFile {
    public static void main(String[] args) {
        String filePath = "path/to/ascii_file.txt"; // 替换为实际的文件路径

        try (BufferedReader br = new BufferedReader(new FileReader(filePath))) {
            String line;
            int row = 0;
            int col = 0;
            int[][] asciiArray = new int[rows][cols];

            while ((line = br.readLine()) != null) {
                for (int i = 0; i < line.length(); i++) {
                    asciiArray[row][col] = (int) line.charAt(i);
                    col++;
                }
                row++;
                col = 0;
            }

            // 打印2D数组
            for (int i = 0; i < asciiArray.length; i++) {
                for (int j = 0; j < asciiArray[i].length; j++) {
                    System.out.print(asciiArray[i][j] + " ");
                }
                System.out.println();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
