Construct or Components of a Method:
1. Header
It is the first line, which contains the access specifier, return type, method name and a list of parameters. Method header is also referred to as method prototype. The compiler checks the compatibility of the values passed to the method and its receiving parameters.
2. Method (Function) Signature
A method signature is the identification of a method. It signifies a method that is to be invoked for a specific operation. It is written using the method name and the parameters to be passed to it. For Example: add(a,b)
3. Access-specifier
Access specifiers deal with the scope of usage of a function. If Public, it can be accessed by any source, even from external class functions. private function can be accessed by a member of only that class. Protected is used for inherited class types.
4. Return type
It is the data type used before the method name in the method header. It indicates the type of outcome of a method to be returned to its caller. In case a method doesn't return any value, its return type is mentioned as void.
5. Function name
Each method includes a name with which it is identified. The function name should preferably be related to the process being carried out in the function.
6. Parameter list
It is a list of variables with their respective data types. Method will receive value based on this list. If it is empty, then it does not receive any value at all.
7. Method block
The function body contains a set of statements which are to be executed. These statements written under method header are enclosed within a pair of curly braces and is known as method block or body of the method.
8. Return statement
A statement that sends back the value from a method to its caller program, is known as Return statement. It is used at the end of a function and can also be called the function terminator. It can only return a single value from a method to its caller. Also, in a function there may be more than one termination point, hence there can be more than one return statement.
