Hi,

i am new in oops programming.

Can you explain me the difference early binding & late binding .

Thanks in advance.

hi :

1(a) early binding called as static binding 1(a) late binding is called as dynamic binding.

2(b)events occurs in compile time 2(b).events occurs at run time.
3(c)functions call are fast.3(c) function calls are slow compare as...
4(d) complete address information are necessary at compile time.4(d) complete address information are necessary at run time..

Value in early binding is passed while writting programes so is unknown to user.while in late binding values are passed by end user on run time

early binding is a binding in which variables are intialized at the compile time


but in late binding variable are initialized at the run time.

I would like to add an example to the above answers.
1.Method overloading is an example for static polymorphism means writing a method with same name with different parameters.By this we can extend the available feature of a method

2.Method overriding is an example for dynamic polymorphism means writing the method with the same name and parameters in a subclass.This is nothing but the code replacement.

early binding and late binding are two important and widely talked issues in OOPs and both vary a lot.
Early binding is also known as static binding which mean when the resouce requirement are known at complile time. for eg. if you declare a variable int rollno then complier will reserve memory at complie time.
on the other hand
late binding:- is also known as dynmic binding which mean when the resouce requirement are not known at complile time.in other words we can say that when resources are bind at run time for eg. if we declare any variable with the use of new operator. then memory requirements are known at run time

any one tell me with simple examples what is polymorphism. and what is the diffrece btwn plymorphism and abstraction.
