Final answer:
Constructors and methods differ in naming conventions: constructors must have the same name as the class with no return type, are called automatically when an object is created, and do not require a return statement, whereas methods follow camelCase, must specify a return type, and perform a specific task but are not automatically called.
Step-by-step explanation:
In terms of naming conventions, constructors and methods in object-oriented programming languages like Java or C# have some distinct differences. A constructor is a special type of method that is used to create and initialize an object, whereas a method is a block of code that performs a specific task and may be called upon multiple times during the lifetime of an object.
- Firstly, a constructor must have the same name as the class in which it is declared and it cannot have a return type, not even void. Methods, on the other hand, can have any name that follows the identifier naming rules and must specify a return type, unless they are intended to return no value, in which case the return type is 'void'.
- Secondly, constructors are called automatically when a new instance of a class is created, so they do not require an explicit return statement. Method names usually follow the camelCase convention, starting with a lowercase letter and capitalizing the first letter of each subsequent concatenated word, with the intention of being descriptive about what the method does.
- Lastly, because constructors are not intended to return a value, they do not provide a return type in their signature, in contrast to methods that may return any data type and must specify this within their signature.
