how to use static variables code example

Example 1: static variables java

Static keyword is used a lot in java. 
 Static means, you
can access those static variables
without creating an object,
just by using a class name.
This means that only one instance of
that static member is created which
is shared across all instances of the class.
Basically we use static keyword when
all members share same instance.

Example 2: what is static variable

The static variable is used to refer to the common property of all objects 
(that is not unique for each object), 
e.g., The company name of employees, college name of students, etc. 
Static variable gets memory only once in the class area at the time of 
class loading. Using a static variable makes your program more 
memory efficient (it saves memory). Static variable belongs to the class 
rather than the object.
