Explain the concept of Generalization

Generalization and inheritance are powerful abstractions for sharing the structure and/or behaviour of more than one class.  Generalization can be defined as a relationship between a class, and it determines a hierarchy of abstraction, in which (one or more) subclasses inherit from (one or more) super classes. Inheritance and generalization are transitive across a subjective number of levels in the hierarchy. Generalization is an "is-a-kind of" relationship, such as, PG student is kind of Student, Saving Account is a kind of Account, etc.  Generalization notation is a triangle connecting a super class to its subclasses. The super class is connected with the help of a line to the top of the triangle. The subclasses are connected through lines to a horizontal bar attached to the base of the triangle. Generalization is a very helpful for both abstract modelling and implementation. Take a look in Figure, a generalization of Account class.
