Java is a most popular, robust, secure, platform independent and multithreading based high level programming language, because of this it is preferably used by many programmers.

4. You will learn the four types of polymorphism in Java-training in this
blog, polymorphism refers to the ability of some entities occur in
different forms.
It is represented popularly by the butterfly, which transforms from larva
to pupa to imago. Polymorphism also exists in programming languages,
as a modeling technique that allows you to create a single interface to
various operands, arguments, and objects. Java polymorphism leads to
code that is more concise and easier to maintain.
While this tutorial focuses on subtype polymorphism, there are several other

Types of polymorphism in Java
There are four types of polymorphism in Java:
1. Coercion is an operation serves multiple types through implicit type
conversion. For example, you divide an integer by another integer or a floating-
point value by another floating-point value. If an operand is an integer and the
other operand is a floating-point value, the compiler (implicitly) forces the

6. 2. What do you mean? Overload refers to the use of the same operator symbol or
method name in different contexts. For example, you can use + to perform
integer addition, floating-point addition, or string concatenation, depending on
the types of its operands. In addition, multiple methods with the same name can
appear in a class (by Declaration and/or inheritance).

7. 3. Parametric polymorphism defines that in a class Declaration, a field name
with different types and a method name with different parameter and return
types can be linked. The field and method can then take different types in each
class instance (object). For example, a field of type Double (A member of the
Java standard class library that encloses a double value) and a method can return
a Double in an object. Java supports parametric polymorphism via generics,
which I will discuss in a future article.

8. 4. Subtype means that a type can serve as a subtype of another type. When a
subtype instance appears in a Supertype context, running a supertype operation
on the subtype instance will cause the subtype to run. For example, consider a
code fragment that draws arbitrary shapes. You can Express these characters
code more concise by introducing a Shape class with a draw () method; by
introducing Circle, Rectangle, and other sub-classes, the draw () override.; and
by calling the draw () method for each instance. When you call draw (), the draw
() method of the Circle, Rectangle, or other Shape instance is called. We say that
there are many forms of the draw () method of Shape.

9. This tutorial introduces the subtype polymorphism. Learn more about upcasting
and late binding, abstract classes (cannot be instantiated) abstract methods
(which can not be called). You will also learn downcasting and runtime type
identification and get a first look at co-variant return types. I save parametric
polymorphism for a future tutorial.
