Washing Machine Task Write a Java program that simulates a washing machine. The graphical user interface consists of two parts: the control panel for setting up washing conditions and the drawing panel for simulating the turbo movement when the machine starts. Note: the example GUI is to illustrate the key interface components rather than suggesting this is the only interface that everyone should stick to. You are encouraged to come up with your own design. Level 1: Appearance and layout Think about appropriate fonts and colours for the labels and the display. Also spend some time on background colours, borders, and the shape of buttons. Work out a layout that resembles a washing machine control panel. Washing machines usually have different interfaces, but they share some common components. You are also encouraged to design a novel interface that you could possibly justify. You may use any number of panels and any layout managers. Level 2: Event handling The toggle “ON/OFF” button tur...

Description: Write a C++ program to assign passenger seats in an airplane. Chesapeake Airlines is a small commuter airline with seats for 36 passengers in 9 rows of 4 seats each. See the sample display below for a layout of the plane. The user enters the row (1 – 9) and the seat (A – D). The program checks the array to see if the seat is available. An X in the array indicates the seat is not available. If the seat is available, assign an X to that position in the array. If it’s unavailable, display a message to the passenger. There are 3 ticket classes: Row 1 = First Class Rows 2-4 = Business Class Rows 5-9 = Coach *Note that the rows are 0-8 in the C++ program. Use the classCtr array supplied in the header file to keep track of how many seats in each class are purchased. Continue processing requests until the user enters -1 for the row. After -1 is entered for the row, display number of seats sold. percentage occupied. sales report. You need to include the following functions in your ...

Project Specifications  Write a C++ program that will use a class called Circle that has the following member variables: radius: a float pi: a float initialized with the value 3.14159. The class should have the following member functions: constructor - sets the radius value = 0.0. setRadius - a mutator function for the radius variable. getRadius - an accessor function for the radius variable. getArea - returns the area of a circle, which is calculated as: area = pi * radius * radius getDiameter - returns the diameter of a circle, which is calculated as: diameter = radius * 2 getCircumference - returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius Write a program that demonstrates the Circle class by asking the user for the circle's radius, creating a Circle object, and then reporting the circle's area, diameter, and circumference with 2 decimal places each.

Description Read a list of friend relations A-B, A-D, C-A, C-D, ..., and determine friendship circles. 2 Problem Statement These days, it seems that we expect computers to direct our social lives, even to the point of choosing our friends. Of course, as programmers, we get to implement these choice algorithms, as in this problem. Given a \friend relation" { a set of pairs of people who designate each other as \friends" { and a particular person (C, \the client") your algorithm is to select any speci ed number (N) of people who are not friends of C, but who are friends of friends of C. Speci cally, the algorithm picks those people who know the greatest numbers of C's friends. For example, if N = 2, C is Jack, and the friend relation is Jack/Mary Mary/Claire Jack/Tom Tom/Claire Jack/Richard Tod/Richard Claire/Richard Jack/Jill Jill/June June/Tod Jill/Tod Jill/Peter Mary/Tom Richard/Tom Jill/Tom the program would select Claire (who knows Jack's friends Mary, Tom, an...

Introduction Answer the following questions from your textbook. You may submit in any format that is neat and readable. Electronic submissions (no required) are to be submitted using D2L on or before the due date. Chapter 21, page 809, exercises 21.25 and 21.26. Explanation Use the following information for both questions: Let us assume a clock with linear time points 0, 1, 2, 3... and that the original read and write timestamps of all items are 0 (without loss of generality). read_TS(X) = read_TS(Y) = read_TS(Z) = 0 write_TS(X) = write_TS(Y) = write_TS(Z) = 0 The two schedules can be written as follows in shorthand notation: SE: r2(Z); r2(Y); w2(Y); r3(Y); r3(Z); r1(X); w1(X); w3(Y); w3(Z); r2(X); r1(Y); w1(Y); w2(X); 1 2 3 4 5 6 7 8 9 10 11 12 13 SF: r3(Y); r3(Z); r1(X); w1(X); w3(Y); w3(Z); r2(Z); r1(Y); w1(Y); r2(Y); w2(Y); r2(X);w2(X); 1 2 3 4 5 6 7 8 9 10 11 12 13 Assume that each operation takes one time unit, so that the numbers under the operations indicate the time when each ...

Description: Implement a priority queue capable of determining what order a list of people should be served given a numeric value. The highest priority should be given to persons with larger values (ordered largest to smallest). The priority queue should be written using a C++ class, named PQueue, and the queue itself should be implemented as a linked list similar to how we implemented queues/stacks in lecture. The following classes should be defined by your program: class Person : Used to store information about each person class PQueue : Priority queue used to serve people The following public functions need to be implemented: Person::Person( int, string ) : Initialize the person PQueue::PQueue( void ) : Initialize the priority queue bool PQueue::empty( void ) : Test whether queue is empty int PQueue::size( void ) : Return size Person* PQueue::front( void ) : Access next node Person* PQueue::back( void ) : Access last node void PQueue::enqueue( Person* ) : Insert node void PQueue::de...

Write SQL statements (queries) to answer the following questions (Make sure to replace XXX with your initials!): 1. Write an SQL statement to list all columns and all rows for the table Service. Save the query results as XXXQ1. 2. Write an SQL statement to list LastName, FirstName, and CellPhone for all employees having an experience level of Master. Save the query results as XXXQ2 3. Write an SQL statement to list the names of employees who have worked on a property in New York. Use a subquery. Save the query results as XXXQ3. 4. Answer question 3 but use a join. Save the query results as XXXQ4. 5. Write an SQL statement to list the names of employees who have worked on a property owned by a corporation. You can use either subquery or join for this question. Save the query results as XXXQ5. 6. Write an SQL statement to show the first name and sum of hours worked for each employee. Save the query results as XXXQ6. 7. Write an SQL statement to show the sum of hours worked for each Exper...
