Answer Posted / ved.b.tripahti
Variables : variables are the place holder for a particular
type of data and this type actually determine how much space
this var will take in the memory.
int varEx = 2; // here varEx is a integer type variable that
take integer literals and will be used as identifier for the
user.
Object : Object shows the behavior that a particular class
can perform.this object is a medium to access the behaviour
of class.
Object may regards as the blue print of a particular class.
Car carObj = new Car(); // carObj is the reference ID of the
Car class.
here -- new Car() is the actual object that will be created
by JVM.
Note :- Object always created using - new keyword.the
identifier before =, is the reference id of new Car() object,
carObj is not the actual object itself.
