![]() The data type ‘public’ enables access to these methods outside their scope of definitions. These methods perform the same addition operation, with changes in the number and data type of the integers. In the above example, the class ‘Calculator’ contains three methods named ‘add()’ with type public. } public double add(double num1, double num2) Public int add(int num1, int num2, int num3) Have a look at this example which illustrates Method Overloading: Java methods can also be overloaded by changing the type or number of parameters. ![]() Overloading is a Java feature that allows a class to have multiple methods working differently with the same name and distinct parameters. ![]() This resolution is achieved using Method Overloading. This ability to allow the same method name to take the input of different parameters enables the reusability of code for the developer at compile-time.Ĭompile-time or Static Polymorphism in JavaĬompile-time Polymorphism occurs when Java resolves the Polymorphism at the time of compilation. Inheritance exists between parent and child classes, where both classes contain the same method name accepting different parameters. Polymorphism comes into play when many classes are interrelated through the concept of Inheritance. This feature is why Java is known as an Object-Oriented rather than an Object-Based language. Polymorphism in Java is a feature which enables Java classes to take on multiple forms of implementations. ![]() This blog offers all you need to know about Polymorphism in Java, such as its types, advantages, and disadvantages.Ī) Compile-time or Static Polymorphism in Javaī) Run-time or Dynamic Polymorphism in Javaģ) Advantages and Disadvantages of Polymorphism in Javaĥ) Conclusion Understanding Polymorphism in Java? Java makes its classes capable of offering various implementations for a method depending on the object passed on to that method. This statistic illustrates Java’s popularity for developing applications and Web applets due to its user-friendly nature and high-level language. Hence, this feature illustrates the use of a single class in Java for many other purposes in the program.Īccording to a Statista survey, nearly 33% of the respondents were Java developers, making it the sixth most commonly used programming language of 2022. The term “Poly” from this word translates to “many”, and the term “morph” translates to “forms”. Java is a programming language containing an essential feature of Object-Oriented Programming, such as Polymorphism. ![]()
