What are state transition diagrams? Where are they used? - Question & Answer Book

 

Answer: State transition have been used right from the beginning in object-oriented modelling. The basic idea is to define a machine that has a number of states (hence the term finite state machine). The machine receives events from the outside world, and each event can cause the machine to transition from one state to another. It is used in AI, Automata theory and Object Oriented Modelling.
