在java中使用绝对路径读取CSV文件时出现异常

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

public class ReadCSVFile {
    public static void main(String[] args) {
        String filePath = "C:/path/to/file.csv";
        
        try {
            File file = new File(filePath);
            FileReader fileReader = new FileReader(file);
            BufferedReader bufferedReader = new BufferedReader(fileReader);
            
            String line;
            while ((line = bufferedReader.readLine()) != null) {
                // 处理每一行数据
                System.out.println(line);
            }
            
            bufferedReader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
