如何在Java中将两个文本文件的数据逐行写入第三个文件中？

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

public class FileMerge {
    public static void main(String[] args) {
        String file1Path = "file1.txt";
        String file2Path = "file2.txt";
        String file3Path = "file3.txt";

        try {
            // 打开输入流和输出流
            BufferedReader reader1 = new BufferedReader(new FileReader(file1Path));
            BufferedReader reader2 = new BufferedReader(new FileReader(file2Path));
            BufferedWriter writer = new BufferedWriter(new FileWriter(file3Path));

            String line;

            // 逐行读取第一个文件的数据并写入第三个文件
            while ((line = reader1.readLine()) != null) {
                writer.write(line);
                writer.newLine();
            }

            // 逐行读取第二个文件的数据并写入第三个文件
            while ((line = reader2.readLine()) != null) {
                writer.write(line);
                writer.newLine();
            }

            // 关闭输入流和输出流
            reader1.close();
            reader2.close();
            writer.close();

            System.out.println("文件合并成功！");
        } catch (IOException e) {
            System.out.println("文件合并失败：" + e.getMessage());
        }
    }
}
