Question

I need to create a data structure that is of the following syntax:

[
 status: "success",
 statusDescription: "statusDescription"
 count: "5",
 states: [
  [stateId: "1", stateDescription: "1 description"],
  [stateId: "2", stateDescription: "2 description"],
  [stateId: "3", stateDescription: "3 description"],
  [stateId: "4", stateDescription: "4 description"],
  [stateId: "5", stateDescription: "5 description"]

 ]
]

I’m not sure how to do that in Java. I’m trying various combinations of ArrayLists and Maps, but can’t quite get it.

EDIT: I actually need to return this data type as a response to a JAX-WS @WebMethod call. Creating a separate class, especially one with a List element is causing problems.

Answer 1

Build your own class. Please.

class Foo {
  private final String status;
  private final String statusDescription;
  private final int count;
  private final List<State> states;
}

class State {
  private final int stateId;
  private final String stateDescription;
}
