What is the process of defining two or more methods within the same class
The only required elements of a method declaration are the method's return type, name, a pair of parentheses, Show More generally, method declarations have six components, in order:
Modifiers, return types, and parameters will be discussed later in this lesson. Exceptions are discussed in a later lesson. Definition: Two of the components of a method declaration comprise the method signature—the method's name and the parameter types. The signature of the method declared above is: calculateAnswer(double, int, double, double) Naming a MethodAlthough a method name can be any legal identifier, code conventions restrict method names. By convention, method names should be a verb in lowercase or a multi-word name that begins with a verb in lowercase, followed by adjectives, nouns, etc. In multi-word names, the first letter of each of the second and following words should be capitalized. Here are some examples: run runFast getBackground getFinalData compareTo setX isEmpty Typically, a method has a unique name within its class. However, a method might have the same name as other methods due to method overloading. Overloading MethodsThe Java programming language supports overloading methods, and Java can distinguish between methods with different method signatures. This means that methods within a class can have the same name if they have different parameter lists (there are some qualifications to this that will be discussed in the lesson titled "Interfaces and Inheritance"). Suppose that you have a class that can use calligraphy to draw various types of data (strings, integers, and so on) and that contains a method for drawing each data type. It is cumbersome to use a new name for each method—for example, calculateAnswer(double, int, double, double)0, calculateAnswer(double, int, double, double)1, calculateAnswer(double, int, double, double)2, and so on. In the Java programming language, you can use the same name for all the drawing methods but pass a different argument list to each method. Thus, the data drawing class might declare four methods named calculateAnswer(double, int, double, double)3, each of which has a different parameter list. public class DataArtist { ... public void draw(String s) { ... } public void draw(int i) { ... } public void draw(double f) { ... } public void draw(int i, double f) { ... } } Overloaded methods are differentiated by the number and the type of the arguments passed into the method. In the code sample, calculateAnswer(double, int, double, double)4 and calculateAnswer(double, int, double, double)5 are distinct and unique methods because they require different argument types. You cannot declare more than one method with the same name and the same number and type of arguments, because the compiler cannot tell them apart. The compiler does not consider return type when differentiating methods, so you cannot declare two methods with the same signature even if they have a different return type. For explanation I would say: Two or more methods can have same name as long as their parameters declaration is different, the methods are said to be overloaded and process is called method overloading. Method overloading is a way by which Java implements polymorphism. Two or more methods can have same name as long as their parameters declaration is different, the methods are said to be overloaded and process is called method overloading. Method overloading is a way by which Java implements polymorphism. This section of our 1000+ Java MCQs focuses on overloading methods & argument passing in Java Programming Language. 1.

What is the process of defining more than one method in a class with the same name?Explanation: Function overloading is a process of defining more than one method in a class with same name differentiated by function signature i:e return type or parameters type and number.
What is the process of defining a method in a subclass having same?Explanation: When a method in a subclass has the same name and type signatures as a method in the superclass, then the method in the subclass overrides the method in the superclass.
What is the process of defining a method in terms of itself?Recursion is the process of defining something in terms of itself. Recursion is sometimes called circular definition. A function that calls itself is said to be recursive.
