Inheritance—>(Is-A relationship)

Every properties and behaviour of parent class can be accessed by derived class

class A//base class

{

}

class B extends A//derived class

{

class Vehicle

class Car extends Vehicle

Car IS-A Vehicle

drawback:

In Inheritance,tight coupling(strong coupling) happens when a subclass is highly dependent on a specific superclass

changes in the superclass will heavily impact the subclass
