“Variable is a name of memory location or name of reserved area allocated in
memory.”
There are three types of variables in java
1- local variable 2- instance variable 3- static variable

A variable that is declared inside the method
is called local variable. A variable that is
declared inside the class but outside the
method is called instance variable . It is not
declared as static. A variable that is declared
as static is called static variable. It cannot be
local.
