What is the notation for a composite state?

• A. Round-Angle
• B. Round-Angle that has nested substates
• C. Circle
• D. Rectangle

Answer: (B)

Hierarchical behavior in a state machine is represented by a composite state, which is a state that contains other states inside it. The notation for this is a rounded rectangle that encloses nested substates. This shows that when the system is in the composite state, it can be in one of its internal substates, providing a hierarchical organization of states. So the correct notation is a round-edged shape that has nested substates inside. A plain rounded rectangle is just a single state, a circle is used for initial (and sometimes final) states, and a rectangle isn’t the standard state notation in this context.
