inheritane in java code example
Example 1: Inheritance in java
class Animal
{
void eating()
{
System.out.println("animal eating");
}
}
class Lion extends Animal
{
void roar()
{
System.out.println("lion roaring");
}
}
public class Cub extends Lion
{
void born()
{
System.out.println("cub drinking milk");
}
public static void main(String[] args)
{
Animal obj1 = new Animal();
obj1.eating();
Lion obj2 = new Lion();
obj2.eating();
obj2.roar();
Cub obj3 = new Cub();
obj3.eating();
obj3.roar();
obj3.born();
}
}
Example 2: inheritance in java
it is used to define relationship between two class,
which a child class occurs all the properties and
behaviours of a parent class.
Provides code reusability.
Ex: in my framework I have a TestBase
class which I store
all my reusable code and methods.
My test execution classes and
elements classes will extend the
TestBase in order to reuse the code.
Example 3: inheritance in java
Inheritance in Java is a mechanism in which one object acquires
all the properties and behaviors of a parent object.
It is an important part of OOPs (Object Oriented programming system).
