- 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_forwardTravel Tickets Company sells tickets for airlines, tours, and other travel-related services. Because ticket agents frequently mistype long ticket numbers, Travel Tickets has asked you to write an application that indicates invalid ticket number entries. The class prompts a ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you drop the last digit of the number, then divide the number by 7, the remainder of the division will be identical to the last dropped digit. Accept the ticket number from the agent and verify whether it is a valid number. Test the application with the following ticket numbers: . 123454; the comparison should evaluate to true . 147103; the comparison should evaluate to true . 154123; the comparison should evaluate to false Save the program as TicketNumber.java.arrow_forwardThe method isupper() returns true if a string is in uppercase and false otherwise.True or Falsearrow_forward

This corresponds to the Select a Solving Method dropdown list in the Solver Parameters dialog box EngineDesc – optional -this is an alternate way of selecting the solving method – here you would type the strings “Simplex LP”, “GRG Nonlinear” or “Evolutionary”.

Prompt the user for an input value and try the Math.sqrt() method on it. The application either displays the square root or catches the thrown Exception and displays an appropriate message. 2.

Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tellsthe ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not.. Test your application with the following ticket numbers: - 123454; is a valid ticket number - 147103; is a valid ticket number -…arrow_forwardIn this assignment you will use the MyString class that you wrote earlier in this course. A palindrome is a string that reads the same forward and backward. Write a program that reads in any number of MyStrings from the user and determines if each MyString is a palindrome. The user will terminate each MyString by pressing the return (or enter) button. The user will indicate that there are no more MyStrings by entering "quit". To do this you must write a recursive function named isAPalindrome that takes a single MyString argument and two arguments that are bounds on MyString indices. The function must examine the part of the argument between the two bounds (including the bounds) and return true if this part of the argument is a palindrome, false if it is not a palindrome. The function must be recursive and must not call any other functions except ispunct(), isspace(), and toupper() (described below). Do not make any changes to the MyString class (except, if necessary, to correct errors…arrow_forward
