Convert byte [] to ArrayList<Object>
提问by evan
I have a byte [] that i obtained using Object ArrayList
我有一个使用 Object ArrayList 获得的字节 []
Can anyone tell me how to convert my byte [] to Object ArrayList?
谁能告诉我如何将我的字节 [] 转换为 Object ArrayList？
coveting arraylist like this
ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = null; oos = new ObjectOutputStream(bos); oos.writeObject(mArrayList);//mArrayList is the array to convert byte[] buff = bos.toByteArray();
垂涎这样的arraylist
ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = null; oos = new ObjectOutputStream(bos); oos.writeObject(mArrayList);//mArrayList is the array to convert byte[] buff = bos.toByteArray();
Thank you!
谢谢！

Now you've given us the information about how you did the conversion one way... you need:
现在您已经向我们提供了有关您如何以一种方式进行转换的信息……您需要：
ObjectInputStream ois = new ObjectInputStream(new ByteArrayInputStream(bytes));
try {
@SuppressWarnings("unchecked")
ArrayList<Object> list = (ArrayList<Object>) ois.readObject();
...
} finally {
ois.close();
}

I'm going to go with the obvious answer here...
我将在这里给出明显的答案......
for(byte b : bytearray) {
arraylist.add(new Byte(b));
}
