Deserializing a json object using gson only on certain fields [duplicate]

Question

If I have a class say

class A
{
String field1
String field2
String field3
}

And I have another class B that contains the following

{
String field1
String field2
}

There is a byte array of key value pairs, [#maps to field1, #maps to field2] How can I using gson map the byte array to the fields in class A without creating a class B that contains the exact number of fields in the map ?

Can I exclude field3 while deserialization ? How do I do that ?

The best approach would be to mark field3 as

transient

Gson will not populate (deserialize) its value from the string.. Alternatively, you can use a custom deserializer implementation which would selectively deserialize things. Here is a link for this kind of solution.
