What is abstraction and its types?

Abstraction can be of two types, namely, data abstraction and control abstraction. Data abstraction means hiding the details about the data and control abstraction means hiding the implementation details. In object-oriented approach, one can abstract both data and functions.

What is generalization in lesson plan?

Generalization is the ability to use skills that a student has learned in new and different environments. Whether those skills are functional or academic, once a skill is learned, it needs to be used in multiple settings. This is also known as community-based instruction or learning transfer.

How do you implement abstraction?

Data abstraction is a method where essential elements are displayed to the user and trivial elements are kept hidden. In Java, abstraction is achieved by using the abstract keyword for classes and interfaces. In abstract classes, we can have abstract methods as well as concrete methods.
