 ## Explanation

 Real world example
 
-> When observing a mammoth in its natural habitat it seems to change its behavior based on the situation. It may first appear calm but over time when it detects a threat it gets angry and dangerous to its surroundings.

 Wikipedia says
 
-> The state pattern is a behavioral software design pattern that allows an object to alter its behavior when its internal state changes. This pattern is close to the concept of finite-state machines. The state pattern can be interpreted as a strategy pattern, which is able to switch a strategy through invocations of methods defined in the pattern's interface.

 Use the State pattern in either of the following cases
 
 * An object's behavior depends on its state, and it must change its behavior at run-time depending on that state
