Chapter 14, Problem 8PC

Program Plan Intro

Program plan:

• Include necessary header files.
• Define a class “StopWatchApplet”.
  • Declare and initialize the necessary variables.
  • Define a method “init()”.
    • Declare the necessary methods to initialize the “StopWatchApplet”.
  • Define a method “reset()” to clear the time.
  • Define a method “update()”.
    • The “if” loop check the conditions for the variables “milliseconds”, “seconds”, and “minute” to update the “StopWatchApplet”.
  • Define a method “changeLabel()”.
    • The “if” loop check the conditions for the variables “hour”, “minute”, “seconds” and “milliseconds” to display the time.
    • Define a method “run()” to start the “StopWatchApplet”.
  • Define a method “actionPerformed()”.
    • The “if” loop check the source is equal to “start”.
      • Initialize the variable “b” as “true”.
      • Call the method “Thread()” to start.
    • The “if” loop check the source is equal to “stop”.
      • Initialize the variable “b” as “false”.
    • The “if” loop check the source is equal to “reset”.
      • Initialize the variable “b” as “false”.
      • Call the method “reset()”.
      • Call the method “changeLabel()”.
