In this activity, you will modify a method (function) to simulate a financial transaction check. Just like when you use your debit card at an ATM. The requested transaction either gets accepted or declined by the bank. By modifying an if-else statement you will be able to perform this check. If the transaction requested cannot be processed due to insufficient funds, tell the user. If the transaction can succeed, then tell the user that that is the case. Your task: Add to the MathMachine.java file so that it has a complete codelblock called the transactionRequest() method. Fill in the Boolean logic in the if statement so that the correct message is sent to the user. Notice the use of this.cardBalance inside the MathMachine class. See how it is private to the MathMachine class? Consider how it might be used in your transactionRequest() method to solve the boolean logic issue. The keyword "this" means "this class". In our example, it means that we're dealing with the MathMachine class. (See "Encapsulation and Information Hiding" in Ch. 1 and "What is This?" in Ch. 6 of the textbook)

Finish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.
Program - Python Make a class.The most important thing is to write a simple class, create TWO different instances, and then be able to do something. For example, create a pizza instance for Suzie, ask her for the toppings from the choices, and store her pizza order. Then create a second pizza instance for Larry, ask for his toppings and store his pizza order. Then print both of their orders back out. You do not need to make your class very complicated. (Shouldn't be the pizza example but something similar)
Create a method where a goblin will attack a zombie as long as the zombie has no health, otherwise the zombie is already dead. If the zombie has 0 or less health, the attack method should add 10 health to the zombie, bringing them closer to being alive so that they will be dead it should then return the zombies health. If the health of the zombie is positive the attack method should return "Zombie is alive, therefore it is not a zombie!". NOTE: This problem statement is extremely vague. This is to test how well you follow directions.
basic java please Write a method called findTip that finds the value of a meal as a double after adding the tip to the cost. Then return this value to the calling function. For example findTip(120.10, 5) would 126.105 because that is a 5% tip. While findTip(48.0, 15) would return 55.2 because that is a 15% tip. Note that the bill is a double while the tip is an int. Don’t worry about rounding to two decimal places, just return the full value as a double.
canMove(int x, int y, int destX, int destY, Side s): This method returns true if the player of color s can move the piece at coordinates (x,y) can move to coordinates (destX, destY) on the board in its current state. This means that here you do need to consider this piece’s interaction with other pieces on the board. Conditions for this method to return false are given in the code. public boolean canMove(int x, int y, int destX, int destY, Side s){ /* TODO write a method that checks if a piece at coordinates x,y can move to coordinates destX,destY Conditions for false: - Origin or destination coordinates are outside the board - Piece at origin is null - If source and destination coordinates are the same - Piece at origin is not of the same side as s - You can check this using piece.getSide() - Piece cannot move to the destination by piece movement rules - You should check this using Piece.canMove(destX,…
Instructor note: This lab is part of the assignment for this chapter. This lab uses two Java files, LabProgram.java and SimpleCar.java. The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 miles
Design a class called Stopwatch. The job of this class is to simulate a stopwatch. It should provide two methods: Start and Stop. We call the start method first, and the stop method next. Then we ask the stopwatch about the duration between start and stop. Duration should be a value in TimeSpan. Display the duration on the console. We should also be able to use a stopwatch multiple times. So we may start and stop it and then start and stop it again. Make sure the duration value each time is calculated properly. We should not be able to start a stopwatch twice in a row (because that may overwrite the initial start time). So the class should throw an InvalidOperationException if its started twice. 1
Please use java only. In this assignment, you will implement a simple game in a class called SimpleGame. This game has 2 options for the user playing. Based on user input, the user can choose to either convert time, from seconds to hours, minutes, and seconds, or calculate the sum of all digits in an integer. At the beginning of the game, the user will be prompted to input either 1 or 2, to indicate which option of the game they want to play. 1 will indicate converting time, and 2 will indicate calculating the sum of digits in an integer. For converting time, the user will be prompted to input a number of seconds (as an int) and the program will call a method that will convert the seconds to time, in the format hours:minutes:seconds, and print the result. For example, if the user enters 6734, the program will print the time, 1:52:14. As another example, if the user enters 10,000, the program should print 2:46:39. For calculating the sum of digits in an integer, the user will be…
Your task is to write a program that computes paychecks. Employees are paid an hourly rate for each hour worked; however, if they worked more than 40 hours per week, they are paid at 150 percent of the regular rate for those overtime hours. Name an actor class that would be appropriate for implementing this program . Then name a class that isn't an actor class that would be an appropriate alternative. How does the choice between these alternatives affect the program structure? Implement the appropriate class and solve the problem. You need to test your code using a separate main class program named "exel.java” Java
Use Java program to add a method printReceipt to the CashRegister class. The method should print the prices of all purchased items and the total amount due. Hint: You will need to form a string of all prices. Use the concat method of the String class to add additional items to that string. To turn a price into a string, use the call String.valueOf(price). Also, the payment information will need to be the same as the price information. Here is the CashRegister class: /** A cash register totals up sales and computes change due.*/public class CashRegister{ private double purchase; private double payment; /** Constructs a cash register with no money in it. */ public CashRegister() { purchase = 0; payment = 0; } /** Records the sale of an item. @param amount the price of the item */ public void recordPurchase(double amount) { purchase = purchase + amount; } /** Processes a payment received from the customer. @param…
Program63.javaWrite a program that estimates the cost of carpet for one or more rooms with rectangular floors. Begin by prompting for the price of carpet per square yard and the number of rooms needing this carpet. Use a loop to prompt for the floor dimensions of each room in feet. In this loop, call a value-returning method with the dimensions and carpet price as arguments. The method should return the carpet cost for each room to main, where it will be printed and accumulated. After all rooms have been processed, the program should display the total cost of the job.Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.
The class provided represents a car. Information about a car includes the brand name of the car and the year it was manufactured. When ordering cars they are ordered in descending alphabetical order by their brand name (z-a). If cars have the same brand name then they are ordered in ascending order by their year. Here is an example of some ordered cars: 2019 Toyota 2012 Subaru 2017 Subaru 2019 Mazda 2018 Kia The Car class is missing a required method. Write the missing method in the space provided below. public class Car implements Comparable { private String brand; private int year; public Car (String brandIn, int yearIn) { brand= brandIn; year = yearIn; } //Write the missing method for this class here.
