182. Local Variables and Instance Variables

Variable is a name of the memory location.

Example -

int var = 5;

Here var is the variable. It stores the assigned value 5 in its memory location.

What are Local Variables ?

A variable that is declared inside the method is called as Local Variable.

What are Instance Variables ?

A variable that is declared inside the Class but outside the methods is called as Instance Variable.

Example of Local Variable and Instance Variable 

Class One
{
         int var1 = 5;   // Instance variable (Declared inside the Class One but is not inside any method)

        two( )
        {
               int var2 = 8;   //Local variable (Declared inside the method)
         }
 
}

So, variables declared inside the methods of Class are Local Variables and inside the Class but outside the methods are Instance Variables.
