Benefits and Costs of Inheritance in java





The inheritance is the core and more usful concept Object Oriented Programming. It proWith inheritance, we will be able to override the methods of the base class so that the meaningful implementation of the base class method can be designed in the derived class. An inheritance leads to less development and maintenance costs.vides lot of benefits and few of them are listed below.

Benefits of Inheritance

  • Inheritance helps in code reuse. The child class may use the code defined in the parent class without re-writing it.
  • Inheritance can save time and effort as the main code need not be written again.
  • Inheritance provides a clear model structure which is easy to understand.
  • An inheritance leads to less development and maintenance costs.
  • With inheritance, we will be able to override the methods of the base class so that the meaningful implementation of the base class method can be designed in the derived class. An inheritance leads to less development and maintenance costs.
  • In inheritance base class can decide to keep some data private so that it cannot be altered by the derived class.

Costs of Inheritance

  • Inheritance decreases the execution speed due to the increased time and effort it takes, the program to jump through all the levels of overloaded classes.
  • Inheritance makes the two classes (base and inherited class) get tightly coupled. This means one cannot be used independently of each other.
  • The changes made in the parent class will affect the behavior of child class too.
  • The overuse of inheritance makes the program more complex.
