Can you explain what the Pageable interface is in the context of development?

The Pageable interface in Java is often used to support pagination — dividing a large dataset into pages. It defines parameters needed to request a specific page of data, such as page number, page size, and sorting.

For example, in Spring Data, Pageable allows you to specify which part of the data to retrieve from the repository:

Pageable pageable = PageRequest.of(0, 10, Sort.by("name"));
Page<User> usersPage = userRepository.findAll(pageable);

Here:

• 0 — page number (the first page)
• 10 — number of items per page
• Sort.by("name") — sorting by the name field

Thus, Pageable helps efficiently work with large volumes of data by loading it in parts and improving application performance.
