Travel Tickets Company sells tickets for airlines, tours, and other travel-related services. Because ticket agents frequently mistype long ticket numbers, Travel Tickets has asked you to write an application that indicates invalid ticket number entries. The class prompts a ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you drop the last digit of the number, then divide the number by 7, the remainder of the division will be identical to the last dropped digit. Accept the ticket number from the agent and verify whether it is a valid number. Test the application with the following ticket numbers: . 123454; the comparison should evaluate to true . 147103; the comparison should evaluate to true . 154123; the comparison should evaluate to false Save the program as TicketNumber.java.

3. Magic Square: Create a class MagicSquare that prompts the user for a positive odd integer size, generates a normal magic square of order size, and prints it with numbers right-justified and aligned in evenly-spaced columns. You may assume the numbers in the square are 3 digits or less (i.e. size ≤31). However, each space-separated column should have a width equal to the largest integer in the magic square. (See example transcripts below.) To generate the magic square, use the following algorithm: Assign 1 to our initial current position: the bottom row, middle column. Place each successive value (up to size * size) in the first of the following positions that is unoccupied: (1) one space down and to the right, or (2) one space up. Positions wrap around the sides, top and bottom, as shown in the following example transcripts (user input underlined): Please enter a positive odd integer: 3 492 357 8 16 Please enter a positive odd integer: 5 11 18 25 2 9 10 12 19 21 3 4 6 13 20 22 23 5…

Java Programming Travel Tickets Company sells tickets for airlines, tours, and other travel-related services. Because ticket agents frequently mistype long ticket numbers, Travel Tickets has asked you to write an application that indicates invalid ticket number entries. The class prompts a ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you drop the last digit of the number, then divide the number by 7, the remainder of the division will be identical to the last dropped digit. This process is illustrated in the following example: Step 1. Enter the ticket number; for example, 123454. Step 2. Remove the last digit, leaving 12345. Step 3. Determine the remainder when the ticket number is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4. Assign the Boolean value of the comparison between the remainder and the digit dropped from the ticket number. Step 5. Display the result—true or false—in a message box. Accept the…
Assignment4B: Diamonds in the sky. In our earliest labs, we asked you to print a diamond pattern to the screen using predefined print statements. Now that we know how to use loops, we can make more dynamic and customizable patterns. For this assignment, we will prompt the user to enter a maximum width for the diamond. If they enter a number less than 3, we'll prompt them to choose a correct width. If they enter an even number (greater than 3), we will add 1 to it and let the user know the final diamond size. Then we will generate and print out the diamond using * and '' symbols. Hints: Each line of the "diamond" is made up of two parts – the asterisks in the center and the spaces to the left of it. The amount of "left space" decreases as we go towards the middle diamond, then increases afterwards as we go towards the bottom. Could we use multiple loops (or even nested loops) to model this behavior? Also, note that the number of asterisks increases (and later decreases) by two on each…
Analyze the following code: int x = 0;int y = ((x < 100) && (x > 0)) ? 1: -1; The code has syntax error. y becomes 1 after the code is executed. y becomes -1 after the code is executed. The code has run time error.
Assignment Description This program will simulate part of the game of Yahtzee! This is a dice game that involves rolling five dice and scoring points based on what show up on those five dice. The players would record their scores on a score card, and then total them up, and the player with the larger total wins the game. A Yahtzee score card has two portions: The upper portion has spaces for six scores, obtained by adding up all of the 1's, 2's, 3's, etc. The lower portion has special scores for various combinations: Three of a kind -- at least 3 dice are the same number;the score is the sum of all five dice Four of a kind -- at least 4 dice are the same number;the score is the sum of all five dice Small straight -- four consecutive numbers are represented, e.g. 2345;the score is 25 points Large straight -- five consecutive numbers are represented, e.g. 23456;the score is 30 points Full House -- three of one kind, two of another; the score is 30 points Yahtzee! -- five of a kind; the…
