what is finalmethod & final variable with example?
Answer Posted / pavan
final method or variable is nothing but once if we declare
as it is final the value of that variable cant be changed
and becomes const.
Example:
--------
final b=200;
Here the value of b is 200 thought the prog
class A
{
void final b=200;
}//A
class B extends class A
{
this.b=201;//Error becoz the variable b is declared as final
//Here this represents the current value i.e.,in
class B that is about variable final
Know coming to the method:
-------------------------
final Add();//similar as variable
Final method can be def as the method name can not be
re-used and at the same time it cant be overridden..
Example:
--------
class A{
final Add()
{
int a,b,c;//Here in this we are adding two int no.
c=a+b;
}
class B extends class A
{
final Add()
{
float a,b,c;//Here we are adding two float no.
c=a+b;
}
