What is a Constructor in Java? In Java, a constructor is a special type of method that is used to initialize objects. When you create an object of a class, the constructor is called automatically. Its main job is to set the initial values of the object’s properties or perform any setup that the object needs before it can be used. Why Do We Need Constructors? You need constructors because: Initialization : Constructors are responsible for initializing an object when it is created. Automatic Execution : A constructor is automatically called when an object is created, so you don’t have to manually initialize every property. Simplifying Object Creation : It simplifies object creation by providing default values or custom initialization. Where Do Constructors Fit in Java? Constructors fit within a class. They are used whenever a new object of that class is created, and they allow the object to be initialized. Constructors must have the same name as the class, and they don't have a re...

Introduction :
The course introduces Java language's syntax and
object-oriented programming paradigms from the perspective of Java language.
Further, the course thoroughly touches upon the vital aspects of the usage of
Java runtime library packages' classes and methods.
-------------------------------------------------------------------------------------------------------------------------
Course Outcomes :
At the end of this course students will be able to
1. Implement Object Oriented Programming paradigm using Java
language.
2. Exhibit the ability to use Java runtime library APIs to
provide a solution to a given problem.
3. Test and debug a Java program for a given problem.

ISE Evaluation: ISE Evaluation
for the course will consist of three programming (hands on) tests.
-------------------------------------------------------------------------------------------------------------------------
Internal Continuous Assessment
(ICA):
ICA shall consist of minimum 15
practical assignment problems.
The assignments should test and
develop student’s practical proficiency and ability to use Java API
Classes correctly for writing
code for varied applications scenarios & use case requirements.
Use of IDEs like BlueJ, Eclipse,
Netbeans or any other FOSS alternative for Interactive development
and debugging of Java
applications is highly recommend to enhance hands on skills in Java
Programming of Students.
