Method Signatures
A method signature is a unique identifier for a method in programming, consisting of its name and the number, types, and order of its parameters. It defines how a method is called and distinguishes it from other methods, especially in overloaded scenarios. Method signatures are fundamental to object-oriented and functional programming for ensuring correct method invocation and polymorphism.
Developers should understand method signatures to write clear, maintainable code and avoid errors in method overloading, inheritance, and interface implementation. They are essential when working with APIs, libraries, or frameworks where precise method calls are required, such as in Java, C#, or Python for defining class behaviors and enabling compile-time type checking.
