how to use ByteArrayOutputStream and DataOutputStream simultaneously (Java)
- by Manuel
Hi!
I'm having quite a problem here, and I think it is because I don't understand very much how I should use the API provided by Java.
I need to write an int and a byte[] into a byte[]
I thought of using a DataOutputStream to solve the data writing with writeInt(int i) and write(byte[] b), and to be able to put that into a byte array, I should use ByteArrayOutputStream's method toByteArray().
I understand that this classes use the Wrapper pattern, so I had two options:
DataOutputStream w = new DataOutputStream(new ByteArrayOutputStream());
or
ByteArrayOutputStream w = new ByteArrayOutputStream(new DataOutputStream());
but in both cases, I "loose" a method. in the first case, I can't access the toByteArray method, and in the second, I can't access the writeInt method.
How should I use this classes together?
