- To encourage good grades, Hermosa High School has decided to award each student a bookstore credit that is 10 times the student’s grade point average. In other words, a student with a 3.2 grade point average receives a $32.0 credit. Create an application that prompts a student for a name and grade point average, and then passes the values to a method (computeDiscount) that displays a descriptive message. The message uses the student’s name, echoes the grade point average, and computes and displays the credit. An example of the program is shown below: Enter your name >> John Enter your gpa >>3.4 John, your GPA is 3.4, so your credit is $34.0arrow_forwardWrite a standard mode application that calculates and displays the weekly salary for an employee. The main() method prompts the user for an hourly pay rate, regular hours, and overtime hours. Create a separate method to calculate overtime pay, which is regular hours times the pay rate plus overtime hours times 1.5 times the pay rate; return the result to the main() method to be displayed. Save the program as Salary.java. Getting errors when I execute.arrow_forwardCreate an application for a library and name it FineForOverdueBooks. TheMain() method asks the user to input the number of books checked out and the number of days they are overdue. Pass those values to a method named DisplayFine that displays the library fine, which is 10 cents per book per day for the first seven days a book is overdue, then 20 cents per book per day for each additional day.arrow_forward
- C# Create an application for a library and name itFineForOverdueBooks. TheMain() method asks the user to input the number of books checked out and the number of days they are overdue. Pass those values to a method named DisplayFine that displays the library fine, which is 10 cents per book per day for the first seven days a book is overdue, then 20 cents per book per day for each additional day. The library fine should be displayed in the following format: The fine for 2 book(s) for 3 day(s) is $0.60 The numbers will vary based on the input. My code is incorrect because its saying "Method DisplayFine displays fine isnt in correct format"arrow_forwardCreate a program named TipCalculation that includes two overloaded methods named DisplayTipInfo. One should accept a meal price and a tip as doubles (for example, 30.00 and 0.20, where 0.20 represents a 20 percent tip). The other should accept a meal price as a double and a tip amount as an integer (for example, 30.00 and 5, where 5 represents a $5 tip). Each method displays the meal price, the tip as a percentage of the meal price, the tip in dollars, and the total of the meal plus the tip. Include a Main() method that demonstrates each method. For example if the input meal price is 30.00 and the tip is 0.20, the output should be: Meal price: $30.00. Tip percent: 0.20 Tip in dollars: $6.00. Total bill $36.00arrow_forwardIn physics, an object that is in motion is said to have kinetic energy. The following formula can be used to determine a moving object’s kinetic energy:KE = 1/2 mv2In the formula KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity in meters per second. Create an application that allows the user to enter an object’s mass and velocity and then displays the object’s kinetic energy. The application should have a method named KineticEnergy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The method should return the amount of kinetic energy that the object has.arrow_forward
- Using Visual Studio , C# Demonstrate the method in an application that lets the user experiment with different values for the formulas terms. Form will have 3 text boxes and labels, a calculate button and an exit button. Text boxes hold future value desired , how many years to grow, and annual interest rate. Calculate button will calculate how much the initial deposit needs to be depending on user input of the 3 text boxes. Write a method named PresentValue. Write a value returning PresentValue method that takes several arguments and computes the presentValue. Write a call to the method that sends the values held in the several variables that have been input. Use the Math.Pow(x,y) method for raising a number to a power in the math. Use a decimal value (not a decimal data type) for annual interest rate. For example: 4% interest rate, must be entered 0.04. Years is also a decimal value. Years is also a decimal valuearrow_forwardjava Temperature Conversions Follow the following methods to get answer Method celsius returns the Celsius equivalent of a Fahrenheit temperature, using the calculation celsius = 5.0 / 9.0 * (fahrenheit - 32); Method fahrenheit returns the Fahrenheit equivalent of a Celsius temperature, using the calculation fahrenheit = 9.0 / 5.0 * celsius + 32; Use methods from part a and b to write application that lets the user either to enter Fahrenheit temps and display the Celsius equivalents or to enter Celsius temperatures and display the Fahrenheit equivalent value. Provide a menu to the user to input 1 for “Fahrenheit to Celsius”, 2 for “Celsius to Fahrenheit”, and 3 for leave program. Use a loop for repetition.arrow_forwardMethods with an empty parameter list and do not return a value: [Questions 1-8 required] You invoke a method by its name followed by a pair of brackets and the usual semi-colon Write a method called DisplayPersonalInfo(). This method will display your name, school, program and your favorite course. Call the DisplayPersonalInfo() method from your program Main() method Write a method called CalculateTuition(). This method will prompt the user for the number of courses that she is currently taking and then calculate and display the tuition cost. (cost = number of course * 569.99). Call the CalculateTuition() method two times from the same Main() method as in question 1. Write a method call CalculateAreaOfCircle(). This method will prompt the user for the radius of a circle and then calculate and display the area.[A = πr2].Call the CalculateAreaOfCircle() method twice from the same Main() method as in question 1. Use Math.Pi for the value of π Write a method call…arrow_forward
- Hello, i need help with this question There are 12 inches in a foot and 3 feet in a yard. Create a class named InchConversion. Its main() method accepts a value in inches from a user at the keyboard, and in turn passes the entered value to two methods. One converts the value from inches to feet, and the other converts the same value from inches to yards. Each method displays the results with appropriate explanation. Save the application as InchConversion.java.arrow_forwardPlease provide Java source code for following project with proper comments. Write a program that asks the user to enter a distance in meters. The program will then pre-sent the following menu of selections: Convert to kilometers Convert to inches Convert to feet Quit the program The program will convert the distance to kilometers, inches, or feet, depending on the user’s selection. Here are the specific requirements: Write a void method named showKilometers, which accepts the number of meters as an argument. The method should display the argument converted to kilometers. Convert the meters to kilometers using the following formula: kilometers = meters * 0.001 Write a void method named showInches, which accepts the number of meters as an argument. The method should display the argument converted to inches. Convert the meters to inches using the following formula: inches = meters * 39.37 Write a void method named showFeet, which accepts the number of meters as an argument.…arrow_forwardWhen an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period: d = ½ gt2 The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the amount of time, in seconds, that the object has been falling. 5.3.1. Create a method: FallingDistance Parameters: t, object’s falling time (in seconds) t may or may not be an integer value! Return value: the distance, in meters, that the object has fallen during that time interval Calculations: Use Math.Pow() to calculated the square in the formula 5.3.2. Demonstrate the method by calling it from a loop that passes the values 1 through 20 as arguments, and displays each returned value. Sample output lines: . . . t = 5, d = 122.5 . . . t = 10, d = 490 . . . Your output should have lines for t=1, t=2, t=3, . . . t=20.arrow_forward
