Linear (or Procedural) Programming is marked by sequential processing: statements are executed in a sequential order, one after the next, in an orderly, linear fashion. The only exception is when there's a call to a function/module; execution momentarily moves to the module and then returns back to the calling point after all statements in the called module complete. Processing then resumes in sequential order again. If event-driven programming depends on user/program/OS interaction and actions to trigger the events, how does an event-driven Java program even start??? And, once started, how does it continue and when does it end???
