The best way to handle this situation is to use a custom JsonConverter.
Before we get to the converter, we'll need to define a class to deserialize the data into. For the Categories property that can vary between a single item and an array,...
Why don't Java Generics support primitive types?
...de both behavioral parametricity (generic methods) and data parametricity (raw and wildcard instantiations of generic types.)
...
a homogeneous translation strategy was chosen, where generic type variables are erased to their bounds as they are incorporated into bytecode. This means that wheth...
Uncaught SyntaxError: Unexpected token with JSON.parse

Creating an instance of class
... type Foo in dynamic memory. foo1 points to it. Normally, you wouldn't use raw pointers in C++, but rather a smart pointer. If Foo was a POD-type, this would perform value-initialization (it doesn't apply here).
/* 2 */ Foo* foo2 = new Foo;
