Object is needed to access a non static data member

U cant call other class method without object.static member 
is common for all object.if u want set some values for 
specific object then the object is necessary

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.

The question is "when we can access the static data member
with out creating object?

To access a static member of data we no need to create an
object, using class name we can access that static data member.

What is the need of the object in java?

Object is required to access the instance variables as well
as instance methods in the class.With out the object we
can't access them.
