Polymorphism java definition code#

In the above example, the CompileTime class has two functions, both having the same name, but in the first function, we pass a string and long as an argument, and in the second function, we pass two strings as an argument. Passing different numbers of arguments to the function. In other words, a class can have multiple methods of the same name, and each method can be differentiated either by bypassing different types of parameters or bypassing a different number of parameters. In this way, we achieve method overloading. To overcome this problem, we pass a different number of arguments to the method or different types of arguments to the method. It will be difficult for the compiler to distinguish between every method. Method overloadingĬonsider a class where multiple methods have the same name. In this process, an overloaded method is resolved at compile time rather than resolving at runtime. It can be achieved by method overloading. This type of polymorphism in Java is also called static polymorphism or static method dispatch.

There are two main types of polymorphism in Java. By the principle of inheritance and polymorphism, each subclass can define its way of living with the help of the live() method. Subclasses of Livingthings i.e., Animals, Humanbeing, and Plants have their way of living. In the above example, the parent class Livingthings has the method live().

The below code is the basic example of polymorphism in Java. In the further article, we will be discussing all the topics related to polymorphism in Java in more detail. Polymorphism in Java is mainly divided into two types.Ĭompile-time polymorphism can be achieved by method overloading, and Runtime polymorphism can be achieved by method overriding. Polymorphism in Java can be achieved in two ways i.e., method overloading and method overriding.

How can polymorphism be achieved in Java? A single interface having multiple implementations is also called polymorphism. The definition of polymorphism can be explained as performing a single task in different ways. We can say that both woman and carbon show different characteristics at the same time according to the situation. She can be a mother, a daughter, or a wife, so the same lady possesses different behavior in different situations.Īnother example of polymorphism can be seen in carbon, as carbon can exist in many forms, i.e., diamond, graphite, coal, etc. Let us understand the definition of polymorphism by an example a lady can have different characteristics simultaneously. In simple words, we can say that ability of a message to be represented in many forms. The word polymorphism can be broken down into Poly and morphs, as “Poly” means many and “Morphs” means forms. Polymorphism is one of the main aspects of Object-Oriented Programming(OOP).
