Interview Questions and Answers for 'Daffodil Software' - 3 question(s) found - Order By Newest Basic and Very Frequently asked. Q1. What is Polymorphism in Java ? Core Java 2016-11-06 09:10:54
Ans. Polymorphism means the condition of occurring in several different forms.
Polymorphism in Java is achieved in two manners
1. Static polymorphism is the polymorphic resolution identified at compile time and is achieved through function overloading whereas
2. Dynamic polymorphism is the polymorphic resolution identified at runtime and is achieved through method overriding. Sample Code for overloading Sample Code for overriding Help us improve.

If everything is an object , Cant we declare every object as
Object obj = new String(); Shouldn't we make a class with all static members is its just expected to be executed as a standalone program with just one thread. Moreover Lets assume that there is no runtime Polymorphism required and there is no need for serialization ? Is this Polymorphism ?
Map<String, List<String>> inventoryManagerCountMap = new HashMap<String, ArrayList<String>>(); When are static and instance methods resolved ? During compile time or Runtime ? Which of the following is not the difference between Singleton and Static class ( Class with static members only ) ? Which of the following do you think is the primary reason you would never use a static class even the application doesn't need multiple requests or threads ?
a. Serialization
b. Runtime Polymorphism
c. Lazy Loading
d. Memory How is static and dynamic polymorphism achieved in Java ? Why do we need polymorphism in Java ? Q2. Can you give a real world example of Encapsulation and Abstraction ? Core Java 2016-05-29 13:47:31
Ans. Car Engine is an example of encapsulation and abstraction. You ignite the car using an interface called starter and least bothered about how the tire actually moves (This is abstraction). The engine encapsulates the complete process to itself only and doesn't allow you to start the other components like the radiator etc ( this is excapsulation ) Help us improve.
