Java-Types of Variables / Chapter - 5 /Language Fundamental

Based on the position of declaration & behavior all variables are divided into three parts.

1.instance variable

2.static variable

3.local variable

 

1.instance variable:-

• If the value of a variable varied from object to object is called Instance variable.


• For every object, a separate copy of instance variable will be created.


• Instance variable should be declared within the class directly, but outside of any method/block/constructor.

• For every object, a separate copy of instance variable will be created.
• Instance variable should be declared within the class directly, but outside of any method/block/constructor.
• Instance variable will be created at the time of object creation & destroyed at the time of object destruction. So the scope of the instance variable is exactly same as the scope of the object.
• Instance variable will be stored in the HEAP memory as the part of an object.
• We can't access the instance variable directly from STATIC area, but we can access it by using "object reference".
•  We can   access the instance variable directly from instance area.
