Key Classes

State Class

• Purpose:
  This class represents the state of a process.

• Attributes:

  • state (int): Can hold the following values:
    • -1: "等待中" (Waiting)
    • 0: "进行中" (In Progress)
    • 1: "已完成" (Completed)

• Methods:

  • getState(): Returns the current state as an integer.
  • toString(): Provides a string description of the current state in Chinese.
  • changeState(): Advances the state sequentially from -1 to 0 to 1, where 1 is the terminal state.

---

Features

• State Transitions:
  Seamless transitions between the states: Waiting, In Progress, and Completed.

• Error Handling:
  If an invalid state is detected, it returns "错误" (Error).

• Change Logic:
  Prevents state transitions beyond the terminal state (1), ensuring logical state progression.
