Q) Key points about Inheritance implementation in java?





A)
->java doesn’t support multiple inheritance.
->super classes are generalized classes. Whereas sub classes are specialized classed.
->the bottom most classes in the hierarchy contain more specialized and the top most classes in the hierarchy contains more generalization.
->super class reference can refer to subclass object.
->As java supports single inheritance. It also supports two special cases of single inheritance
1. Multilevel inheritance.
2. Hierarchical inheritance.
->if a super class has more than one sub classes, it is known as hierarchical inheritance.
                               
                              
Hierarchical inheritance
->if a sub c lass is acting as a super class for another sub class, that form of inheritance is known as multilevel inheritance.
                               
                                              
-> Java.long.Object class is super class of all java classes.
-> Sub class objects substitute super class object in the application.
->inheritance provides reusability of code.
Security provided by encapsulation

JDBC driver role: They are 4 roles   1)       Establishing connection between JDBC client and database server. 2)       Receiving JDBC method calls made by JDBC client while performing database (CRUD) operations. 3)       Translating java method calls into DBMS understandable calls and forwarding them to database server. 4)       Receiving the results from database server.
