what is inheritance in java with example

Example 1: inheritance in java

// super class
class Animal
{
   void eat()
   {
      System.out.println("Animal is eating.");
   }
}
// subclass
class Lion extends Animal
{
   public static void main(String[] args)
   {
      Lion obj = new Lion();
      obj.eat();
   }
}

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.
