9. Methods and Constructors
Methods in Java are blocks of code that execute tasks and define object behavior, allowing for code reusability and organization. Constructors are specialized methods that initialize object attributes upon creation. Constructor overloading permits multiple constructors with different parameters, enhancing flexibility in object initialization. The 'this' keyword helps distinguish between class attributes and method parameters, further facilitating proper object management.

What we have learnt
- Methods execute specific tasks and define the behavior of objects.
- Constructors initialize objects and set their initial attributes.
- Constructor overloading allows for multiple ways to initialize objects based on parameters.
- The 'this' keyword differentiates between parameters and instance variables.
Key Concepts
- -- Method
- A block of code in Java that performs a specific task and can return a value or execute an action.
- -- Constructor
- A special method for initializing objects; automatically called upon object creation.
- -- Constructor Overloading
- The ability to define multiple constructors in a class, distinguished by parameter lists.
- -- this Keyword
- A reference to the current object, distinguishing between instance variables and parameters within methods.
