Can you explain the mechanism of the MVP pattern in software development?

The MVP pattern (Model-View-Presenter) divides application logic into three components:

• Model — responsible for data and business logic.
• View — displays data and interacts with the user.
• Presenter — acts as an intermediary between Model and View, handles user actions, updates the View, and requests data from the Model.

This separation simplifies testing and maintaining the code, as the logic is separated from the interface.

An example of a simplified structure in Kotlin for Android:

interface View {
    fun showData(data: String)
}

class Model {
    fun getData(): String = "Data from model"
}

class Presenter(private val view: View, private val model: Model) {
    fun onViewReady() {
        val data = model.getData()
        view.showData(data)
    }
}

Here, the Presenter retrieves data from the Model and passes it to the View for display.
