如何在java中添加UTF-8 BOM

import java.io.*;

public class AddBOMExample {
    public static void main(String[] args) {
        try {
            FileOutputStream fos = new FileOutputStream("output.txt");
            OutputStreamWriter osw = new OutputStreamWriter(fos, "UTF-8");
            
            // 写入BOM
            osw.write('\uFEFF');
            
            // 写入文本内容
            osw.write("这是一个使用UTF-8编码的文本文件。");
            
            osw.close();
            fos.close();
            
            System.out.println("UTF-8 BOM已成功添加到文件中。");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
