This document discusses different types of inheritance in object-oriented programming, including single inheritance where a class extends one other class, multilevel inheritance where a derived class inherits from another derived class, and multiple inheritance where a class can inherit from more than one parent class, which is achieved through interfaces. It provides examples of code implementing single inheritance with a BaseClass and DerivedClass, and multiple inheritance using interfaces Car and Bus implemented by the Vehicle class.

1.  Single Inheritance
 Multiple Inheritance
 Multilevel Inheritance
 Hierarchical Inheritance
 Hybrid Inheritance

2.  When a class extends another class (only one
class) then we call it as single inheritance.
Class A
Class B

3. public class BaseClass
{
Public void display()
{
System,out.println(“ this is base class”);
}
}
Public classs DerivedClass extends BaseClass
{ public void disp()
{
System.out.println(“this is derived class”);
}
Public static void main(String args[])
{

4. DerivedClass D= new DerivedClass()
D.display();
D.disp();
}
}
OUTPUT
This is base class
This is derived class

5.  When one class extending more then one
class is called multiple inheritance.
 It can be achieved by using Interfaces.
Class A Class B
Class C

6. Interface Car
{
Int speed=60;
Public void distanceTravelled();
}
Interface Bus
{
Int distance=100;
Public void spped();
}
Public class Vehicle implements Car,Bus
{
Int avgdistance, avgspeed;
Public void distanceTravelled()
{
Avgdistance=speed*distance;
System.out.println(“Avg distance=“+avgdistance);

7. }
Public void speed()
{
avgspeed=avgdistance/speed;
System.out.println(“Avg speed=“+avgspeed);
}
Public class void main(String args[])
{
Vehicle v=new Vehicle();
v.distanceTravelled();
v.speed();
}
}

8. Avg distance= 250
Avg speed=80
