Method Overriding vs Method Overloading in OOP

Method overriding and method overloading are two important concepts in OOP:

Method Overloading

Method overloading involves defining multiple methods in a class with the same name but different parameters. The methods must have different signatures, such as different number or types of parameters.

Method Overriding

Method overriding occurs when a subclass provides a specific implementation for a method that is already defined in its superclass. The method signature in the subclass must be identical to the method in the superclass.

Differences

• Method overloading is achieved within the same class, while method overriding occurs between a superclass and its subclass.
• In method overloading, the methods must have different signatures, whereas in method overriding, the method signatures must be identical.
• Method overloading is resolved at compile time based on the method signature, while method overriding is resolved at runtime based on the object type.
