Creating Methods in Java Design and write a Java program that calculates and displays the results of a sales transaction. Two classes are to be defined as follows: Class Name: Sales Input Variables: quantity - an integer value price a floating point value commissionRate - a double value (example: 8.5%) (to be entered as percent discount PerCent - a double value (example: 6.5%) values) Processing: There are four input values as defined above. These variables are to be declared inside main().The main() method of this class should accept the quantity, price, commission rate, and discount percent from the keyboard (echo the inputs back to the screen) and call the appropriate functions described below to calculate the final sales transaction amount. main() should also display the initial sales amount. Methods: saleAmt() - The quantity and price are passed to this method. It returns the sale amount to the calling method. netSale()- The sale amount, commission amount, and discount amount are passed to this method. The commission amount should be added to the sale amount and the discount amount should be subtracted. Return the net sale back to the calling method. finalSale() - This method displays the net sale amount, tax and final sales amount. **You determine appropriate argument passing and return value. SalesCalcs Class Name: Methods: calcComm()- The sale amount and commission rate are passed to this method. It calculates and displays the commission amount and passes this value back to the calling method. calcDisc() - The sale amount and discount percent are passed to this method. It calculates and displays the discount and passes this value back to the calling method. tax() - This method calculates the tax of the net sale amount. **You determine appropriate argument passing and return value. roundMoney() In addition include a utility method to round all calculated values to the nearest cents amount. This method should accept a double or float as its argument and return a float value. I have included a suggested one for your convenience. // Method to round the input value to the nearest "cents" amount public static float round Money(double money) { } int temp; temp = (int)(money 100.00+.5); return (float)temp/100;

Java A class always has a constructor that does not take any parameters even if there are other constructors in the class that take parameters. Choose one of the options:TrueFalse

Use Java Programming Language Create a Loan Account Hierarchy consisting of the following classes: LoanAccount, CarLoan, PrimaryMortgage , UnsecuredLoan, and Address. Each class should be in it's own .java file. The LoanAccount class consists of the following properties: principal- the original amount of the loan. annualInterestRate - the annual interest rate for the loan. It is not static as each loan can have it's own interest rate. months - the number of months in the term of the loan, i.e. the length of the loan. and the following methods: a constructor that takes the three properties as parameters. calculateMonthlyPayment() - takes no parameters and calculates the monthly payment using the same formula as Assignment 1. getters for the three property variables. toString() - displays the information about the principle, annualInterestRate, and months as shown in the example output below. The CarLoan class which is a subclass of the LoanAccount class and consists of the...

Number Guessing Program using java: The player has to guess a number given in between a range. If the guessed number is right, the player wins else, loses. It also has the concept of limited attempts where the player has to guess the number within the limited attempts given. Note: It must incorporates the following OOP components: - Classes - Objects - Constructors - Class Variable - Object Method

CSCI 140/L Java Project: Menu-Driven System Part A Write a menu-driven program that will give the user the three choices: 1) Wage calculator, 2) Coupon Calculator, and 3) Exit. Class Name: PartA Wage Calculator: For the wage calculator, prompt for the name and hourly pay rate of an employee. Here the hourly pay rate is a floating-point number, such as 9ドル.25. Then ask how many hours the employee worked in the past week. Be sure to accept fractional hours. Compute the pay. Any overtime work (over 40 hours per week) is paid at 150 percent of the regular wage (1.5 the hourly pay rate). Print the employee's name, regular hours worked, regular hours pay, overtime hours worked (do not show overtime hours, if there are none), overtime hours pay (do not show overtime pay if there is none), and total pay. [Do not prompt for overtime hours] Coupon Calculator: For the coupon calculator, the total coupon amount is calculated based on the type of items purchased. Ask for the shopper's total purchase...

Portfolio Instructions: You are working for a financial advisor who creates portfolios of financial securities for his clients. A portfolio is a conglomeration of various financial assets, such as stocks and bonds, that together create a balanced collection of investments. When the financial advisor makes a purchase of securities on behalf of a client, a single transaction can include multiple shares of stock or multiple bonds. It is your job to create an object-oriented application that will allow the financial advisor to maintain the portfolios for his/her clients. You will need to create several classes to maintain this information: Security, Stock, Bond, Portfolio, and Date. The characteristics of stocks and bonds in a portfolio are shown below: Stocks: Bonds: Purchase date (Date) Purchase date (Date) Purchase price (double)...

Object-oriented programmingProgram the employee class as indicated in the diagramTo calculate the salary, just multiply the number of hours by the payment per hour.The capture method asks the user for the data for the three attributes, asks for the hours worked and the payment per hour and with these data calculates the salary.The show method displays all of the employee's data.Do not forget the getter and setter methods only for attributes of type privateYour company has 7 employees and you would like1.

Asking help for Java Programming Create a program that simulates a meeting reservation system. Part 1: Basic requirements The program shall allow the user to select from the following options: Create a new meeting Show meetings on the calendar Clear all meetings Each meeting has a subject, start day/time and end day/time Subject is a short text description of the meeting Day is a date that contains month, day, and year Meeting times need only deal with hour and minute When the user wants to create a new meeting, the program asks for the subject, start and end day/times for it and adds it to the calendar For the basic requirements, meetings are not allowed to overlap. If a meeting the user wants to schedule overlaps with an existing meeting, the program presents an error message showing which meeting the one the user wants to schedule overlaps with When the user wants to show all meetings for the week, the report displays all meetings each day as follows Show all meetings...

Data Generator Most application depends on data. In IoT data is collected/generate by sensors. Since, we do not have access to sensors, we will have to generate data via code. The plotting a sufficient number of these data points (500 in this case) should get the following diagram or something very similar: You will pick a quantity that you would like to simulate (such as temperature, humidity, barometric pressure, customers arriving at a mall, or just with an alternate descriptor) and decide what shape you will emulate. This will guide you in selecting sensible value base lines for your data values. e.g., If you pick inside temperature then normal range will be 18-21oC. Design and build a class that will model your sensor reasonably well. Notice how the peaks do not occur at regular interval, nor are they the same height. Even the squiggles are the same shapes. You will create a class with a single public member (property) that give you a "random" value in your intended range and...
