Q) What are the instance variables?




A)
Non-static variables of the class are known as instance variables. For each instance of a class one separate copy of these variables is created and hence the name. Moreover, unless instance is created, they don’t come into existence physically i.e. memory is not allocated for them.
 Ex:
class A
{
  int a;
  int b;
}
->Instance variable contribute to the size of the object.
-> Instance variables are meant for representing individual object information.

Ex: class A {        class B        {                      } //nested class, and inner class.because it is not static class. } //enclosing class or outer class. ->static class is declared in inside an another class then it does not become an inner class. Note: non-static nested class is known as “inner class”. In the above example class B is nested but not an inner class. Ex: class D {        static c        {                      } //nested class, but not an inner class , because of static class. } //outer class. ->we have three different kinds of inner classes. 1) Member inner class 2) Meth...
