Polymorphism contains two words : Poly and Morphism . Poly means many and morphism means ability of an object to take on different forms is known as polymorphism. Polymorphism is the capability of a method to do different things based on the object that it is acting upon.
Polymorphism is a programming language feature that allows values of different data types to be handled using a uniform can see the most common use of polymorphism in OOP so [url=http://www.cheapnflcoltsjerseys.com/braden-smith-jersey/]Braden Smith Womens Jersey[/url] , when a parent class reference is used to refer to java training center bangalore a child class object.
Any Java object that can pass more than one IS-A test is considered to be
polymorphic. In Java,
all Java objects are polymorphic since any object will
pass the IS-A test for their own type and
for the class Object.
We know that only possible way to access an object is through a reference
variable. A reference
variable can be of only one type. Once
declared [url=http://www.cheapnflcoltsjerseys.com/darius-leonard-jersey/]Darius
Leonard Womens Jersey[/url] , the type of a reference variable cannot be
changed.
The reference variable can be reassigned to other java course in bangalore
objects provided that it is not declared final. The type of the reference
variable would determine the methods that it can call on the object.
We
create the reference variable for class as well as for interface.
Polymorphism exists in three distinct forms in Java:
鈥?Method
overloading
鈥?Method overriding through inheritance
鈥?Method overriding
through the Java interface
Types of Polymorphism:
[1]Compile Time
Polymorphism
[2]Run Time Polymorphism
Compile Time Polymorphism: When
method binding happens at compile time is known as compile time polymorphism or
static od binding means when method call get attach with method body.
For
achieving Static binding javaj2ee classes bangalore Method Overloading is
necessary.
Note: Method Overloading means same method name but differs in
number of parameters ,types of parameters and position of parameters.
Run
Time Polymorphism : When method binding happens at run time is known as run time
polymorphism or dynamic getting dynamic binding
inheritance [url=http://www.cheapnflcoltsjerseys.com/quenton-nelson-jersey/]Quenton
Nelson Womens Jersey[/url] ,overriding and upcasting is necessary.
If any one
property not there we can鈥檛 get the run time polymorphism.
Types of
Polymorphism:
[1]Compile Time Polymorphism
[2]Run Time Polymorphism
Difference between Compile Time and Run Time Polymorphism
1)During compile
time source code changes into executable code .but during run time executable
code is used to give output.
2)Error present during compile time could be
compiled Advanced java training in bangalore without error,only syntax of code
has to be correct.
But if logic of code is not correct then it will be
compiled successfully but gives error during runtime.
3)Error during compile
time is due to syntax error but error during runtime is due to logical
error.
Need Of Polymorphism :
1) The basic reason behind polymorphism is
that we can implement different behaviours of the same object depending upon the
reference type passed to an object.
2)

polymorphism [url=http://www.cheapnflcoltsjerseys.com/andrew-luck-jersey/]Andrew
Luck Womens Jersey[/url] ,if not there we have to remember all dependent classes
related to DB, use in our java coding
3) Polymorphism enables us to best core
java training in bangalore define one or more methods to have the same name but
differs in number of parameters and method types.
If we do not have
polymorphism in Java then we cannot overload methods.
