No, a static variable means that there is only one copy of that variable, and it is shared by all members of the class, or by all callers of a function.
A variable that is read-only would be marked as const or final (depending on language).

Are static variables serialized in java?
No, static variables are not serialized.
It is perfectly legal to any instance variable inside of a static method?
No. You will get compilation errors. The complier will complain that you are trying to access non static variables from inside a static method. A static method can access only static variables.
Why memory is divided into initialized and uninitialized areas?
The program's data segment. This area of memory is allocated by the linker and is used to store the program's global variables, static variables, static arrays and constants. Constants are always initialised, as are static variables, but global variables and static arrays need not be initialised.
Are C variables initialized to 0 by default?
Only global/static variables are, local variables aren't.
Can a static method access instance variables?
Variables cannot access variables; only methods can access variables. Non-static methods (also known as instance methods) are local to an object of the class and therefore have access to a "this" reference (referring to the current instance of the class, the object upon which the method was invoked), but static variables are local to the class itself. These variables are shared by all objects of the class and are therefore accessible to non-static methods. Static variable are also accessible to static methods and are therefore accessible even when no objects of the class exist.
Can variables be changed?

Are static variables serialized in java?
No, static variables are not serialized.
Why static functions cannot use instant variables?
Static functions are tied to a class, not to a particular object. A static function can only access static variables because it has no knowledge of member variables.
It is perfectly legal to any instance variable inside of a static method?
No. You will get compilation errors. The complier will complain that you are trying to access non static variables from inside a static method. A static method can access only static variables.
How do you access the static variable and static methods of a class?
In java we access static variables and static methods without creating objects. i.e.,we can access directly by using classname we can also access static variables and static methods by using objects which are created by using class where the static variables and static methods are available
Can non static methods can access static variables?
Yes, they can

Is it possible to write in static variables in main method in java?
Short answer: No. Only class member variables may be declared static. Local variables with a static declaration will throw an error (usually "illegal start of expression").
Are static variable created by giving keyword static in java?
yes bcoz static variables
Where the static variables are stored?
initialize static variables are stored in data segment where uninitialized static variables are stored in BSS(block storing for Symbol) it also a part of data segment exp static int i=10;//stored in data segment static int i;//stored in BSS (uninitialized data segment) Thanks NAvin
