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