   • Overloading overridden method am I overloading parent or sub-class method

     You override something that is inherited, so B.a() overrides A.a(). Overriding means to redefine.

     Overloading is when your class have more than one definition of the same method name (each with different argument types). In B, the name a is overloaded. There is B.a() and B.a(int x).

     Some of the definitions might be inherited. So if you remove B.a(), the class B would still have a method a() since it inherits it from A. And the method name a would still be overloaded in B.

   • overloading method user input

     So what you want to do is make it so the input is a string.

     so the user can input 9, or 9.0 or if you want to get crazy maybe nine.

     then you would parse the string and cast it to an int or a double. then call either of the overloaded methods.

     that shows you how to convert a string to an int

   • Overloading method on extended class

     Top Answer

     Why does y1.f(y2) calls the f() method in A instead of in B?

     Because the compile-time type of y1 is A.

     Overloading is performed at compile-time... the execution-time type of the object you call the method on is only relevant for overriding.

     So the compiler is choosing the method f(A) as that's the only f method it's aware it can call on y1 (and it's checked that it's applicable given the argument list). That method isn't overridden in B, therefore at execution time, the implmenetation in A is called.

     As a starker example, consider this code:

     Object x = "foo";int length = x.length();-

     This won't even compile, because Object doesn't contain a length() method. String does, but the compiler doesn't consider that, because the compile-time type of x is Object, not String - even though we can tell that at execution time, the value of x will be a reference to a String object.

   • Overloading Method with user input

     Inside your getRadius method you are setting a local variable to the value entered by the user:

     int radius = sc.nextInt();

     When you calculate the diameter, area, circumference you're using an instance variable - for example:

     double diameter = 2 * radius;

     Since you never set the instance variable its value by default is 0.

   • Overloading method calls with parameter null

     Top Answer

     Answered Jun 20, 2020 · 17 votes

     It always uses the most specific method according to the Java specs, section 15.12.2.5.

     The intro is reasonably specific about it:

     If more than one member method is both accessible and applicable to a method invocation, it is necessary to choose one to provide the descriptor for the run-time method dispatch. The Java programming language uses the rule that the most specific method is chosen.

     The informal intuition is that one method is more specific than another if any invocation handled by the first method could be passed on to the other one without a compile-time type error.

     Generally speaking, and at least for code readability, it's always best to try to be as explicit as possible. You could cast your null into the type that matches the signature you want to call. But that's definitely a questionable practice. It assumes everyone knows this rule and makes the code more difficult to read.

     But it's a good academic question, so I +1 your question.

   Java Method Overloading. In Java, two or more methods may have the same name if they differ in parameters (different number of parameters, different types of parameters, or both). These methods are called overloaded methods and this feature is called method overloading. For example:

   Jan 8, 2024 · Method overloading is a powerful mechanism that allows us to define cohesive class APIs. To better understand why method overloading is such a valuable feature, let’s see a simple example. Suppose that we’ve written a naive utility class that implements different methods for multiplying two numbers, three numbers, and so on.

   What is method overloading in Java?

   • In Java, Method Overloading allows different methods to have the same name, but different signatures where the signature can differ by the number of input parameters or type of input parameters, or a mixture of both. Method overloading in Java is also known as Compile-time Polymorphism, Static Polymorphism, or Early binding.

   How do I know if a method is overloading?

   • 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Parameters list doesn’t mean the return type of the method, for example if two methods have same name, same parameters and have different return type, then this is not a valid method overloading example. This will throw a compilation error.

   What is the difference between overloading and overriding a method?

   • You saw that the main point of overloading a method is to change its parameter list in order to implement a different behaviour based on the arguments that are passed to it. Overriding, on the other hand, refers to re-defining the same method, with the same parameter list, in a subclass in order to tailor its behaviour to the needs of the subclass.

   Mar 17, 2023 · Method overriding refers to redefining a method in a subclass that already exists in the superclass. When you call an overridden method using an object of the subclass type, Java uses the method's implementation in the subclass rather than the one in the superclass.
