如何用BufferedReader从PrintWriter中读取txt文件来读取带有值的网格坐标？

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

public class GridCoordinatesReader {
    public static void main(String[] args) {
        try {
            // 创建BufferedReader对象来读取txt文件
            BufferedReader reader = new BufferedReader(new FileReader("coordinates.txt"));

            String line;
            while ((line = reader.readLine()) != null) {
                // 拆分每一行的字符串
                String[] coordinates = line.split(" ");

                // 将字符串转换为网格坐标的值
                int x = Integer.parseInt(coordinates[0]);
                int y = Integer.parseInt(coordinates[1]);

                // 进一步处理或存储网格坐标值
                System.out.println("x: " + x + ", y: " + y);
            }

            // 关闭BufferedReader
            reader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
