在Java中使用异步线程编辑文件

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class AsyncFileEditor {
    public static void main(String[] args) {
        ExecutorService executor = Executors.newFixedThreadPool(5); // 创建线程池

        // 提交异步任务
        executor.submit(() -> {
            try {
                editFile("file.txt", "Hello, World!");
            } catch (IOException e) {
                e.printStackTrace();
            }
        });

        // 关闭线程池
        executor.shutdown();
    }

    public static void editFile(String filename, String content) throws IOException {
        BufferedWriter writer = new BufferedWriter(new FileWriter(filename, true));
        writer.write(content);
        writer.newLine();
        writer.close();
    }
}
