Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The main idea of the State Pattern is that, at any given moment, there’s a ____ number of states which a program can be in.
A
infinit
B
finit
C
finalized
D
finished
Explanation: 

Detailed explanation-1: -Finite-State Machine. The main idea is that, at any given moment, there’s a finite number of states which a program can be in. Within any unique state, the program behaves differently, and the program can be switched from one state to another instantaneously.

Detailed explanation-2: -The State Pattern is also known as Objects for States.

Detailed explanation-3: -The State pattern is closely related to the concept of a Finite-State Machine. There is a finite number of states which a program can be in. The main idea is that, at any given moment, there is a finite number of states which a program can be in.

Detailed explanation-4: -A finite state machine describes a computational machine that is in exactly one state at any given time. It can change from one to another state in response to some input / trigger / event. The emphasis of the state design pattern is on encapsulation of behavior to create reusable, maintainable components (the states).
