Clock

Pembuatan Clock menggunakan BlueJ

Class yang digunakan sebagai berikut :

  1. Main Clock : digunakan sebagai penghubung antara NumberDisplay dan ClockMechanics
  2. NumberDisplay : digunakan sebagai format output number pada jam
  3. ClockMechanics : digunakan sebagai pengatur mekanisme jam

Technical Support AI

Technical Support - Artificial Intelligence (*From now on, I'll try my best to explain about all of my Project using English) For this project, I made 3 classes to control the Bot Mechanism (Referencing to Objects-First-with-Java-A-Practical-Introduction-Using-BlueJ-David-J-Barnes pages 155) : InputReader Class (Used for detect or to take any user input) SupportSystem Class (As a main function connecting the user input and database) Responder Class (Handling AI-Output and Its role as 'mini' database) Current Version : 1.2 In the future, I'm expecting to have a bigger Responder's Database and would be separated from the Class itself, so it will be easier to make some modification inside the AI's Database and easier to manage. And then i'll try to improve the UX Design inside, so that the user can have a feeling about how 'Human' this AI. InputReader Class In this class, pretty much the same as how the name of the class is writt
