Question

I have a json string (the stream of social network Qaiku). How can I decode it in Java?
I’ve searched but any results work for me.
Thank you.

Answer 1

As an example using Gson, you could do the following

Gson gson = new Gson();
gson.fromJson(value, type);

where value is your encoded value. The trick comes with the second parameter – the type. You need to know what your decoding and what Java type that JSON will end in.

The following example shows decoding a JSON string into a list of domain objects called Table:

In order to do that the type needs to be specified as:

Type type = new TypeToken<List<Table>>(){}.getType();

Gson is available here:
