Method overloading and overriding are fundamental concepts in Java that often lead to confusion. Let's clarify these concepts with clear examples and explanations. What is Method Overloading? Method overloading occurs when multiple methods in the same class have the same name but different parameters. Here are the conditions for method overloading: 1. Number of parameters is different. 2. Parameter types are different. Examples of Valid and Invalid Method Overloading Let's look at some examples to understand what constitutes valid method overloading: // Valid overloading - different parameter types int changeDate(int year); int changeDate(float year); // Invalid overloading - same parameter types, different return types int changeDate(int month); float changeDate(int year); What is Method Overriding? Method overriding occurs when a subclass provides a specific implementation of a method that is already defined in its superclas
