Q3. 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.

Tell me something about OOPs Core Java 2017-06-13 08:25:45
Ans. OOPs or Object Oriented Programming is a Programming model which is organized around Objects instead of processes. Instead of a process calling series of processes, this model stresses on communication between objects. Objects that all self sustained, provide security by encapsulating it's members and providing abstracted interfaces over the functions it performs. OOP's facilitate the following features
1. Inheritance for Code Reuse
2. Abstraction for modularity, maintenance and agility
3. Encapsulation for security and protected
4. Polymorphism for flexibility and interfacing Help us improve.

Explain static blocks in Java ? Core Java Anonymous
Ans. A static initialization block is a normal block of code enclosed in braces, { }, and preceded by the static keyword. Here is an example:
static {
// whatever code is needed for initialization goes here
}
A class can have any number of static initialization blocks, and they can appear anywhere in the class body. The runtime system guarantees that static initialization blocks are called in the order that they appear in the source code. Help us improve.
