class MyStat
{
static int x=0;
MyStat()
{
x++;
}
public static void main(String arg[])
{
MyStat m1=new MyStat();
MyStat m2=new MyStat();
MyStat m3=new MyStat();

m1.x=80;
m2.x=90;
m3.x=56;
int mx=m1.x;
System.out.println("MyStatic variable: "+mx);
}
}

Hope this helps.
Other Gurus, please correct me if I'm wrong.

As it is said, Final variables CANNOT be modified.
static variables can.

There can be a lot of uses of static variables.
Say I have a class and want to keep track of who
instantiated it last, I can declare a static variable
called "lastAccess" as an int or String and store the
calling method/class (assuming the caller gives me) name
or some form of ID.

The example what you mentioned above is exactly the
same as what is described in RH (page 84-85).

I thought the explanation was good.
Hope this helps.

Btw Prabhu, I am not a Guru in this :-)

Regds.
