Distance TraveLed Modification
The distance a vehicle travels can be calculated as follows:
Write a method named distance that accepts a vehicle’s speed and time as arguments, and returns the distance the vehicle has traveled. Modify the “Distance Traveled” program you wrote in Chapter 4 (

- The program must include two classesclGradesGraph and GradesGrapghDemo. GradesGraphDemo (one method)- Main method only GradesGraph- Include at least 4 methods (No credits without at least 4 methods!!!) Create a class that represents the grade distribution for a given course. In this class you should write methods to perform the following tasks: Read the number of each of the letter grades A, B, C D and F Set the number of letter grades A, B, C, D and F Return the total number of grades Return the percentage of each letter grade as a whole number between 0 and 100 inclusive Draw a bar graph of the grade distributionThe graph should have five bars, one per grade. Each bar can be a horizontal row of asterisks, such that the number of asterisks in a row is proportionate to the percentage of grades in each category. For example, let on asterisk represent 2%, so 50 asterisks correspond to 100%. Mark the horizontal axis at 10% increments from 0 to 100% and label each line with a letter…arrow_forwardTrue or False: When passing multiple arguments to a method, the order in which the arguments are passed is not important.arrow_forwardMicrosoft Visual C# 7th edition, programming exercise 11-3 Instructions: Write the program FindSquareRoot that finds the square root of a user’s input value. The Math class contains a static method named Sqrt() that accepts a double and returns the parameter’s square root. If the user’s entry cannot be converted to a double, display an appropriate message, and set the square root value to 0. Otherwise, test the input number’s value. If it is negative, throw a new ApplicationException to which you pass the message “Number can’t be negative.” and again set sqrt to 0. If the input value is a double and not negative, pass it to the Math.Sqrt() method, and display the returned value. An example of the program is shown below: Enter a number 9 Square root is 3 or Enter a number -9 Error: Number can't be negative. Square root is 0 Here is my code. How can I pass the message to a new ApplicationException and display the error message? Thank you. using System; using static System.Console;…arrow_forward
- A program contains the following value-returning method: private int Square(int value) { return value * value; } Write a statement that passes the value 10 as an argument to this method and assigns its return value to the variable result.arrow_forwardin c# please Write method QualityPoints that inputs a student’s average and returns 4 if the student’s average is 90–100, 3 if the average is 80–89, 2 if the average is 70–79, 1 if the average is 60–69 and 0 if the average is lower than 60. Incorporate the method into an app that reads a value from the user and displays the result.arrow_forwardT/F(If false, correct the statement to make it true) - A void method will return an int valuearrow_forward
- use only C# programming language 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 CalculateAreaOfTriangle(), that prompts the user for the base and height…arrow_forwardBy default, the equals method does the same thing as the operator. == True Falsearrow_forwardJAVA Problem description:You are to write a program called Seasons that prompts the user for a month and day and displays the season in which that date occurs. For reference, we will use the following date cutoffs for the various seasons: Winter December 21 – March 19 Spring March 20th – June 20th Summer June 21st – September 20th Fall September 21st – December 20th Data Validation For this program, you'll write a specific method to perform data validation based on the month and day entered. More specifically: Month – the month entered must be a valid month of the year (January – December). Day – the day entered must be a valid day for that month: January, March, May, July, August, October, December have 1-31 days. April, June, September, November have 1-30 days. February has 1-28 days (do not worry about leap years) Required program decomposition String getMonth(Scanner console) This method is called from the main method and should prompt for the month as a string…arrow_forward

Provide a default value for the running time so that if you call the method without minutes, it defaults to 90.
