What is a method signature example?

A signature is a list that specifies a class constructor, an instance method, or a static method , thereby distinguishing it from other constructors, instance methods, or static methods.

Java. In Java, a method signature is composed of a name and the number, type and order of its parameters . Return types and thrown exceptions are not considered to be a part of the method signature, nor are the names of parameters; they are ignored by the compiler for checking method uniqueness.

You use the final keyword in a method declaration to indicate that the method cannot be overridden by subclasses . The Object class does this—a number of its methods are final .

A function signature (or type signature, or method signature) defines input and output of functions or methods . A signature can include: parameters and their types. a return value and type. exceptions that might be thrown or passed back.

Using signature() function It takes callable as a parameter and returns the annotation . It raises a value Error if no signature is provided. If the Invalid type object is given then it throws a Type Error. Syntax: inspect.signature(callable, *, follow_wrapped=True)

According to Oracle, the method signature is comprised of the name and parameter types . Therefore, all the other elements of the method’s declaration, such as modifiers, return type, parameter names, exception list, and body are not part of the signature.24 Eyl 2020
