Program Plan Intro

Game: play a tic-tac-toe game

Program Plan:

  • Include the necessary package.
  • Define the class named “Exercise08_09”.
    • Declare the object “obj” for scanner class.
    • Define the main method.
      • Declare a variable “brd” for grid board.
      • Call the method “printBoard()” to print the board on screen.
      • Define the “while” loop.
        • Call the method “user_move()” which takes board and symbol.
        • Call the method “printBoard()”.
        • Using “if…else” condition to call the function “check_Won()”.
          • If the condition is true, print “X player won” statement on screen and exit the code.
            • Otherwise, check the “if” condition and call the function “check_draw()”.
              • Print “No winner” on screen and exit the code.
    • Define the method “user_move()” which takes board and user’s symbol.
      • Declare the Boolean variable “done” and assign “false” on screen.
      • Define “do…while” loop.
        • Inside the loop, prompt the value of variables “row” and “column” from user.
        • Using “if…else” condition, initialize the user’s symbol into board and assign “true” to variable “done”.
          • Otherwise, print the statement.
    • Define the method “printBoard()” which takes the board as input.
      • Using “for” loop, print the board with symbols on screen.
    • Define the method “check_won()” which takes character symbol and board as arguments.
      • Using “for” loop and “if” condition, check the values for row, column, major diagonal, and sub diagonal grid values.
    • Define the method “check_draw()” which takes board as input.
      • Using “for” loops, check the grid values.

I would like to get information to know features about the following concepts: 1. Anything as a Server (XaaS) 2. Block Storage 3. WebSocket
Please answer JAVA OOP problem below: You are working at a university that tracks students. Each student is identified by their name and faculty advisor. Each faculty advisor is identified by their name, department, and maximum number of students they can advise. Using solid OO design principles, create a modular program that implements all the classes for the problem and also creates an implementation class that gathers user input for one student and then prints out the information gathered by creating the appropriate data definition and implementation classes. All data must be validated.    I have given the code so far: Implementation: import javax.swing.JOptionPane; public class Implementation {     public static void main(String[] args) {         FacultyAdvisor facultyAdvisor = new FacultyAdvisor("Sharmin Sultana", "IT", 30);         Student student = new Student("John", facultyAdvisor);         JOptionPane.showMessageDialog(null, student.toString());     } }   Student: public…
