Read the passage given below
"Each instance variable is contained in an object. It can be accessed only if you have a reference to that object. No such reference is available to a static method." I dont get the line -if u have a reference to that object Please explain it.

if this is about class variables.
it means that variable that are not declared static can be accessed by using an object(instance) of the class.
ie: object.var
static variables can be accessed without an object
ie: ClassName.var
i'm not sure about the context of your post, so I could be off topic.

Would it probably make a better sense if we replace "have a reference to" by "have access to"?
