Generalization and Specialization in OOP:-

In the real world, you can find many objects that are specialized versions of other more general objects. For example, the term "insect" describes a general type of creature with various characteristics. Because grasshoppers and bumblebees are insects, they have all the general characteristics of an insect. In addition, they have special characteristics of their own. For example, the grasshopper has its jumping ability, and the bumblebee has its stinger. Grasshoppers and bumblebees are specialized versions of an insect. This is illustrated in the Figure (given below).
