MethodDeclaration

MethodDeclaration in programming refers to the definition of a subroutine or function within a class or structure. It specifies the name of the method, the types of parameters it accepts, and the return type of the value it produces. This declaration acts as a blueprint, informing the compiler or interpreter about the method's signature and how it can be invoked.

A typical method declaration includes an access modifier (e.g., public, private), a return type (e.g., int, void, String), the method name, and a list of formal parameters enclosed in parentheses. Each parameter has a type and a name. For instance, in Java, a method declaration might look like public int add(int num1, int num2). This indicates a public method named 'add' that takes two integer arguments and returns an integer.

The body of the method, containing the actual code to be executed, follows the declaration. The declaration itself, however, does not contain the implementation. It serves as the contract for how the method can be called and what kind of data it expects and returns. Method declarations are fundamental to object-oriented programming and procedural programming paradigms, enabling code modularity, reusability, and abstraction. They are essential for structuring programs and defining the behavior of objects or modules.
