android - java generics do not support arrays, so is there any convenient way for RxJava's Map collection to define and obtain a string of common parent class collection data?

Question

I am using just to send the obtained data (json), and then process the obtained data through map and convert it into a map, and then subscribe,
In the actual process, I found that there are many similar operations, so I want to encapsulate them. I want to use generics for the target collection data obtained in map To stipulate,
But in the process of converting json data to a collection, an array of class objects is needed, and arrays do not support generics. So what is the solution for brothers who encounter similar problems? How to deal with it? Thanks!

Answer 1

Do I have to use an array? Lists and the like can also be substituted
