使用java逐行读取csv并将其连接为字符串

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

public class CSVReader {
    public static String readAndConcatenateCSV(String filePath) throws IOException {
        StringBuilder sb = new StringBuilder();

        try (BufferedReader br = new BufferedReader(new FileReader(filePath))) {
            String line;
            while ((line = br.readLine()) != null) {
                sb.append(line);
                sb.append("\n"); // 如果需要保留行间分隔符，可以加上此行代码
            }
        }

        return sb.toString();
    }

    public static void main(String[] args) {
        String filePath = "path/to/your/csv/file.csv";
        try {
            String concatenatedString = readAndConcatenateCSV(filePath);
            System.out.println(concatenatedString);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
