推荐答案

该文件是什么格式?将其转换为字节数组，可能已经有一个可用的函数.

此代码与String相同:

What format is that file? turn it into a byte-Array, there might be a function for that already available.

This code does the same with a String:

String strFilePath = "demo.txt";  
try {
  FileOutputStream oStream = new FileOutputStream(strFilePath);
  String strContent = "Write File using Java FileOutputStream example !";
  oStream.write(strContent.getBytes());
  oStream.close();
}
catch(Exception oException) {
  System.out.println("OOOPS : " + oException);
}
