Arguments: Arguments are actual values passed into a method when it is called. They correspond to the parameters defined in the method's declaration.
Return type: The return type specifies the type of value that a method will return after its execution. Parameters help determine what inputs are needed for the method, while return types define what output can be expected.
Method signature: A method signature consists of its name and parameter list. It uniquely identifies a specific method within a class and helps differentiate it from other methods with similar names but different parameters.
