Overloading in Java. Overriding and Overloading are two very important concepts in Java. They are confusing for Java novice programmers. This post illustrates their differences by using two simple examples. Definitions. Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding means having two methods with the same method name and parameters (i. One of the methods is in the parent class and the other is in the child class.
Overriding allows a child class to provide a specific implementation of a method that is already provided its parent class. Overloading. Here are some important facts about Overriding and Overloading: 1). The real object type in the run- time, not the reference variable's type, determines which overridden method is used at runtime. In contrast, reference type determines which overloaded method will be used at compile time.
Strategy Design Pattern in Java Example Tutorial. Strategy Pattern Class Diagram, example code of strategy algorithms at runtime. This post is similar to Overriding equals method in Java. Consider the following Java program: // file name: Main.java class Complex
Polymorphism applies to overriding, not to overloading. Overriding is a run- time concept while overloading is a compile- time concept.
An Example of Overriding. Here is an example of overriding. After reading the code, guess the output. Dog. During compile time, the compiler checks if the Dog class has the bark() method. As long as the Dog class has the bark() method, the code compilers. At run- time, a Hound is created and assigned to dog. The JVM knows that dog is referring to the object of Hound, so it calls the bark() method of Hound.
This is called Dynamic Polymorphism. An Example of Overloadingclass Dog. Compiler know they are different because they have different method signature (method name and method parameter list).
