Which variable is not destroyed on exit from the function instead its value is presented and becomes available again when the function is next called These variables are declared as?
Local function variables defined static remain in memory at all times. Such variables are only in scope (accessible) when the function itself is in scope.
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.
Why static variables in a function have global extent?
A variable declared static outside of a function has a scope the of the source file only. It is not a global variable. A variable declared outside of a function and without the static qualifier would be a global variable.
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.
What is automatic storage class specifiers?
Automatic storage is the default storage class for all non-static local variables including formal arguments. All automatic variables are allocated on the call stack and are automatically released when they fall from scope.
Is it possible to write in static variables in main method in java?
