Java Method Overloading is an essential concept in Object-Oriented Programming that allows a class to have multiple methods with the same name, differentiated by their parameters. This feature, which is a form of compile-time polymorphism, enhances code readability and reusability. It is used in various scenarios, such as GUI development and database connectivity, to create adaptable and scalable applications. Unlike method overriding, which is runtime polymorphism, overloading is determined at compile time and is crucial for efficient Java development.

Method overloading allows a class to have multiple methods with the same name but different parameters
Type
Parameters can differ in their type, such as accepting an integer or a double
Number
Parameters can differ in the number of parameters they accept
Order
Parameters can differ in the order in which they appear
Method overloading promotes code readability and reusability by allowing the same method name to be used for different but related actions
Overloaded constructors in GUI development facilitate the instantiation of objects with diverse initial states
The 'println()' method in Java's System.out class is a classic example of method overloading
JDBC interfaces leverage method overloading to set parameters for different data types

Method Overloading: Parameter Differences
Overloaded methods must have unique parameter lists by type, number, or order.
01
Compile-Time vs. Run-Time Polymorphism
Method overloading is compile-time (static) polymorphism; resolved by compiler.
02
Method Overloading: Impact on Code Quality
Enhances readability and reusability, allowing similar actions under one method name.
