What is the use of UML state diagram?
Statechart diagram is used to describe the states of different objects in its life cycle. Emphasis is placed on the state changes upon some internal or external events. These states of objects are important to analyze and implement them accurately. Statechart diagrams are very important for describing the states.
A state diagram, sometimes known as a state machine diagram, is a type of behavioral diagram in the Unified Modeling Language (UML) that shows transitions between various objects.

What is a state machine diagram or statechart and what are its uses?
Statechart diagram is used to capture the dynamic aspect of a system. State machine diagrams are used to represent the behavior of an application. An object goes through various states during its lifespan. These diagrams are used to represent various states of a system and entities within the system.
What are the symbols used in state diagram?
A filled circle followed by an arrow represents the object’s initial state. An arrow pointing to a filled circle nested inside another circle represents the object’s final state. A short heavy bar with two transitions entering it represents a synchronization of control.
What is state diagram same as?
A state diagram is used to represent the condition of the system or part of the system at finite instances of time. It’s a behavioral diagram and it represents the behavior using finite state transitions. State diagrams are also referred to as State machines and State-chart Diagrams.
Are state diagram and activity diagram same?
Activity diagram is essentially a flowchart showing flow of control from activity to activity. A state chart diagram shows a state machine emphasizing the flow of control from state to state.
