java class inheritance example

Example 1: Inheritance in java

// Multiple inheritance in java
interface M
{
   public void helloWorld();
}
interface N
{
   public void helloWorld();
}
// implementing interfaces
public class MultipleInheritanceExample implements M, N
{
   public void helloWorld()
   {
      System.out.println("helloWorld() method");
   }
   public static void main(String[] args) 
   {
      MultipleInheritanceExample obj = new MultipleInheritanceExample();
      obj.helloWorld();
   }
}

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.
