2. What is a Constructor?
1 Definition
A constructor is a special type of method
that is automatically called when an object
is created.
2 Initialization
It is used to initialize the object's state and
perform any necessary setup.
3. Purpose of Constructors
Object Initialization
Constructors initialize
object variables, ensuring
the object is in a valid
state.
Encapsulation
They help in achieving the
principle of encapsulation
by providing controlled
access.
Code Reusability
Constructors enable code
reusability through the
creation of new objects.
6. Constructor Overloading
1 Multiple Signatures
Enables the creation of multiple
constructors with different parameter
lists.
2 Increased Flexibility
Provides flexibility in object creation
by accommodating various
parameter types.
7. Constructor Chaining
Sequential Invocation
One constructor invoking another to reuse
code and reduce redundancy.
Inheritance Utilization
Helps in utilizing constructors of superclasses
within subclasses.
8. Best Practices for Using Constructors
1
Consistent Naming
Use clear and consistent naming
conventions for constructors.
2 Code Readability
Ensure constructors are easy to
understand and maintain.
3
Parameter Clarity
Provide clear and meaningful
parameters for improved code
comprehension.
