1. Static variables are initialized to zero by default by the compiler.2. Global or static variables are not available, but a DA can call user interface APIs. 3. Since the class does not have any static variables to initialize, the initialization completes trivially. 4. Static variables influence BCF as well.5. Consequently, the type parameter cannot be used in the declaration of static variables or in static methods. 6. Note : static variables do not change from object to object and stay the same for this given class. 7. Static variable binding, like Fortran, was the norm and the use of arbitrary subroutine call patterns was rare.8. The static variables first and last have to be defined, because their declaration does not reserve memory space for them. 9. Programmers can define public and private global data-types, constants and static variables in a PL / SQL package. 10. If the initialization is not done explicitly, external ( static or not ) and local static variables are initialized to zero.
