type of inheritance in java code example
Example 1: multilevel inheritance in java
class Car{
public Car()
{
System.out.println("Class Car");
}
public void vehicleType()
{
System.out.println("Vehicle Type: Car");
}
}
class Maruti extends Car{
public Maruti()
{
System.out.println("Class Maruti");
}
public void brand()
{
System.out.println("Brand: Maruti");
}
public void speed()
{
System.out.println("Max: 90Kmph");
}
}
class Maruti800 extends Maruti{
public Maruti800()
{
System.out.println("Maruti Model: 800");
}
public void speed()
{
System.out.println("Max: 80Kmph");
}
public static void main(String args[])
{
Maruti800 obj=new Maruti800();
obj.vehicleType();
obj.brand();
obj.speed();
}
}
Example 2: java program to demonstrate multilevel inheritance
Class X
{
public void methodX()
{
System.out.println("Class X method");
}
}
Class Y extends X
{
public void methodY()
{
System.out.println("class Y method");
}
}
Class Z extends Y
{
public void methodZ()
{
System.out.println("class Z method");
}
public static void main(String args[])
{
Z obj = new Z();
obj.methodX(); //calling grand parent class method
obj.methodY(); //calling parent class method
obj.methodZ(); //calling local method
}
}
Example 3: 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.
