如何使用FileWriter写入相同的CSV文件

import java.io.FileWriter;
import java.io.IOException;

String filePath = "path/to/your/file.csv";
FileWriter fileWriter = new FileWriter(filePath);

String data = "John,Doe,25\n";

fileWriter.write(data);

fileWriter.flush();

fileWriter.close();

import java.io.FileWriter;
import java.io.IOException;

public class CSVWriterExample {
    public static void main(String[] args) {
        String filePath = "path/to/your/file.csv";
        try {
            FileWriter fileWriter = new FileWriter(filePath);

            // 写入第一行数据
            String data = "Name,Age,Country\n";
            fileWriter.write(data);

            // 写入第二行数据
            data = "John,Doe,25\n";
            fileWriter.write(data);

            // 写入第三行数据
            data = "Jane,Smith,30\n";
            fileWriter.write(data);

            fileWriter.flush();
            fileWriter.close();

            System.out.println("CSV文件写入完成。");
        } catch (IOException e) {
            System.out.println("写入CSV文件时出错：" + e.getMessage());
        }
    }
}
