Answer / k.gnaneshwar

*-> Constructor is used for initializing the variables
during object creation.
*-> that means the code required for initializing the
variable should be writen in constructor.
CONSTRUCTOR DECLARATION RULES
* Constructor look like a method.
* Constructor have no return type.
* Constructor name should be same name as the class name.

(prog)

class simpleAddition
{
int a,b; //variable declaration
simpleAddition() //constructor declaration
{
a=6;
b=3;
}
int add() // method declaration
{
return a+b;
}
}

output:- 9

Answer / kousik

Main Advantage of Cons:
1)Object Initialization
2)Class don't have Private access specifier through use of private constructor avoid inheritance.
3)Types:a)static b)Instance
a)--Default automatically crates and no arguments are not supplied.
b)-Same name of class but we have n no of arguments.

Answer / kamlesh sharma

I am not a Great programmer,i dont know to write a single
line of code also, so i am explaning constructor in words,
without giving you an example program.

frankly to tell, i just watched like a movie when my friend
was typing about constructor,i know only eating, chating,
drinking, sleeping.

My friend just wrote my Name because he don't like to
propagate his name.

And my friend Name is Phani and anyone can contact him at:
phani121@yahoo.co.in, because he is a gem in programming
languages.
