Static data is class level data,while objects contain
values of non static instancs varibles.
diffrent object contains diffrent values of instance
varibles ,
but all object can share same vale of static data.
Class abc{
int i;
int j;
static int x=10;
//-----some more code
}
diffrent object contain diffrent values of i&j,
but all object can share one value of x(ie 10 coz it is
static).
static data is accessed by class name and object also.
