Polymorphism in Java is another important feature of OOPs concept. We have seen an overview of polymorphism in the tutorial OOPs concepts in Java. In this tutorial, we will understand in detail about polymorphism and its different types. We will cover about Static Polymorphism, Dynamic Polymorphism, Runtime Polymorphism.
What is polymorphism in Java
Polymorphism in Java as the name suggests means the ability to take multiple forms. It is derived from the Greek words where Poly means many and morph means forms. In Java, polymorphism in java is that the same method can be implemented in different ways. To understand this, we need to have an idea of inheritance in java as well which we have learned in the previous tutorial.
Types of Polymorphism in Java
Below are the different types of polymorphism in java.
Static Polymorphism
When we overload a static method, we call it as static polymorphism. Since it resolves the polymorphism during compile time, we can call also name it as compile-time polymorphism. We can implement this type of polymorphism in java using either method overloading or operator overloading. In static polymorphism, during compile time it identifies which method to call based on the parameters we pass.
Let's understand this in detail with the help of examples.
Method overloading
When there are many methods with the same name but different implementations, we call it a method overloading.
This is the skull of “Java Man” (homo erectus). Eugene Dubois discovered it in 1891. This is a clear display of the ongoing search, and passion many scientists have that drive them to explore and investigate the history of the world. And analyze it in with the hope of finding scientific explanations for human curiosity regarding our heritage, ancestors and even the origin of life. The New York Times article we read this week states that, “experimental/observational methods all the natural sciences share, the social sciences increasingly adopt, and that naturalists devote themselves to making explicit. You can reject naturalists’ epistemology, or treat it as question begging, but you can’t accuse them of not having one.” Which explains how important and valid it is for all educated people to have a point of view and a purpose to their investigation.

The Java sparrow (Lonchura oryzivora), also known as Java finch, Java rice sparrow or Java rice bird, is a small passerine bird.[2] This estrildid finch is a resident breeding bird in Java, Bali and Bawean in Indonesia. It is a popular cage bird, and has been introduced in a large number of other countries. Some taxonomists place this and the Timor sparrow in their own genus Padda. The Java sparrow is about 15 to 17 cm (5.9 to 6.7 in) in length from the beak to its tip of tail feathers. Although only about the size of a house sparrow, it may be the largest species in the estrildid family. The adult is unmistakable, with its grey upperparts and breast, pink belly, white-cheeked black head, red eye-ring, pink feet and thick red bill.
Both sexes are similar. Immature birds have brown upperparts and pale brown underparts, and a plain head. Very young birds have a black beak with a pink base.
The call is a chip, and the song is a rapid series of call notes chipchipchipchipchipchip.
Molecular phylogeny indicates that this species may have originated in India and dispersed to Africa and Pacific Ocean habitats from there.
