A Seminarobject is fairly complex, reacting to events such a enrolling a studentdifferently depending on its current state, as you see depicted in Figure 1. The final state is denoted by a circle with a dot inside and may also be labeled with a name. A State Machine diagram shows a series of conditions which an object can take up over its lifespan, and the causes of the state changes. This isnt the whole UML project of ATM but this are the major Diagrams which frequently occur in University Papers. State machine diagrams can also show how an entity responds to various events by changing from one state to another. State diagrams are a powerful mechanism for formalizing dynamics that can express several aspects of a class. A state is a condition during the life of an object which it may either satisfy some condition for performing some activities, or waiting for some events to be received.
