Write the following program in java:

• Create Classes: Mammal, Reptile, Bird
• Each class has two instances variables -- name (String) and legs (int)
• Create constructor(s) to initialize the object.
• Each class has two methods:

   String info() { return "I am " + name + ", I have " + legs + " legs". } void say() { System.out.println(info()); } 

• Create a driver class and provide main() method.
• In main(), create 10 objects of Mammal, Reptile, and Bird in random order, then use a loop to display .say() of each object.
• Apply subtype polymorphism solution with abstract class.
