what is finalmethod & final variable with example?..

Final method cannot be overridden by subclasses. This is
used to prevent unexpected behavior from a subclass
altering a method.

Example:

public class MyClass {
public final void myFinalMethod() {...}

Final Variable, it can only be assigned to once and only in
the constructor of class if variable is not a reference to
pther object.

Example:

public class Sphere {

public static final double PI = 3.141592653589793; //
this might as well be a constant
public final double xpos;
public final double ypos;
public final double zpos;

Sphere(double x, double y, double z, double r) {
xpos = x;
ypos = y;
zpos = z;
}

what is finalmethod & final variable with example?..

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 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{
{
int a,b,c;//Here in this we are adding two int no.
c=a+b;
}
class B extends class A
{
{
float a,b,c;//Here we are adding two float no.
c=a+b;
}
