Question

I am reading multiple differing json files from server which needs to be re-used again. Some of the json files are using the same tree structure.

To accomplish this task is this the best method –

Define an interface which has getter/setter methods from below json and then an implementing class which creates a new object based on json. Is creating an interface for this task overkill ?

{
"type":"test", 
"children":[
    {
    "id":testId,
    "type":"laptop",
    "price":"500",
    }
]
}

Answer 1

I don’t think this would be overkill, if you are creating different objects and you are going to need the same attributes, then I would say this is the right approach.

You can also consider using a factory pattern.
