Types of Variables in JAVA | Primitive, Reference, Instance, Static & Local variables

#TypesOfVariablesinJAVA #InstanceVariable #StaticVariable #LocalVariable

Based on the type of value represented by a variable.
1. primitive variable
2. Reference variable.

Based on the behaviour and position of declaration all variables are divided into 3 types.

1. Instance variable
2. Static variable
3. Local variable

1. Instance variable:-
====================
- If the value of a variable is varied from object to object such type
variables are called instance variables.
- For every object a separte copy of instance variables will be created.
- Instance variables will be created at the time of object creation and
destroyed at the time of object destrction and hence the scope of the
instance variables is exactly same as scope of the object.
- Instance variables will be stored on the heap as the part of object.
- Instance variables can be accessed directly from instance area. But
cannot be accessed directly from static area.
- But by using object reference we can access instance variables from
static area.

2.Static variable:-
=================
- If the value of a variable is not varied from object to object such
type variables are called static variables.
- The entire class will be created and shared by every object of that
class.
- static variables will be created at the time of class loading and
destroyed at the time of class unloading and hence the scope of the
static variables is exactly same as scope of ".class file".
- Static variables can be accessed from both static and instance area.
- We can access static variables either by using classname or objectname
or individual

3. Local variable:-
==================
