How to get ajax site load data using java?

Question

Java

Hello, I am writing an application for an android phone, an assignment at the university.
You need to learn how to get information from a site that has ajax loading.
For example, the ozone ru website, I enter a search for any product, I take the url of the page, I load it in my application, I parse using the library. And everything would be fine, but only the first page of the search can be loaded this way, the rest are loaded using ajax, and I don’t know how to get them. I hope I explained it clearly, can you advise something?)
