Write a Java console program that allows students to schedule 1 hour appointments at either 1, 2, 3, 4, 5, or 6 o'clock (pm only). Declare an array that can hold exactly 6 Strings, one for each name of the person who will be scheduled for the appointment at a particular hour. Write a loop that prompts the user to enter an integer value for the time they wish to schedule an appointment. Within a try block, allow the user to enter a time (whole number) and a name. If the time is free, put the name in the array at that timeslot. If the time is not free, throw a TimeInUseException (create custom exception class). If the time is not valid, throw an InvalidTimeException (create custom exception class). Use a catch block to handle both exceptions.

Write a method that accepts a string object as an argument and returns the number of words it contains. for instance, if the argument is "four score and seven years ago", the method should return the number 6. demonstrate the method in a program that asks the user to input a string and then passes that string into the method, printing out whatever the method returns.

Design a class tictactoe that: holds the following information about the game: two-dimensional array (3 by 3), and winner. add additional variables as needed. includes the functions to perform the various operations on objects. for example, function to print the board, getting the move, checking if move is valid, determining if there is a winner after each move. add additional operations as needed. includes constructor(s). write the functions of the class, and write a program that uses the class. the program should declare an object of type tictactoe. the program will create the board and store it in the array. the program will allow two players to play the tic-tac-toe game. after every valid move update the array, check if there is a winner. if there is no winner and no tie, then print the board again to continue.
