How to work with MySql database using Retrofit2?

Question

Java

You need to connect and process POST / GET requests, but it's not very clear how to do this with MySql, because in all articles on Retrofit2 they offer work with JSON databases, like jsonplaceholde. Please help me figure this out, and also please advise something similar to jsonplaceholde, but with mysql.

Answer 1

You need to write a REST API server to access the data, retrofit is an HTTP client to work with the API.

Answer 2

Apparently, right?
$array = ;

Answer 3

$array = [];
for ($n = 0; $n<100; $n++) {
    $array[] = ['field' => $n];
}

It is necessary?
