try {
FileInputStream fis = new FileInputStream(f);
Log.d("Objects remaining; ", fis.available()+"");
ObjectInputStream ois = new ObjectInputStream(fis);
Log.d("Objects remaining; ", fis.available() + "");
Question question = (Question) ois.readObject();
Log.d("FIS:",fis.toString());
Log.d("OIS:",ois.toString());
} catch (Exception e){
e.printStackTrace();
}
}
我不知道如何处理代码中给定的异常。

最佳答案
流上有 4 个字节可用。您的序列化 Question 对象可能会大于四个字节。我认为这会产生EOFException。您已通过打印堆栈跟踪来处理异常。您确定该文件包含您所期望的内容吗？
