1. A showChar MethodWrite a method named showChar. The method should accept two arguments: a reference toa String object and an integer. The integer argument is a character position within theString, with the first character being at position 0. When the method executes, it shoulddisplay the character at that character position. The method does not return anything.Here is an example of a call to the method:showChar("New York", 2);In this call, the method will display the character w because it is in position 2. Demonstratethe method in a complete program-- use the class name Method_showChar
Java
Write a method that accepts a string as an argument and checks it for proper capitalization and punctuation. The method should determine if the string begins with an uppercase letter and ends with a punctuation mark. The method should return true if the string meets the criteria; otherwise it should return false.
Travel 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.

- Carly’s Catering provides meals for parties and special events. In previous chapters, you have developed a class that holds catering event information and an application that tests the methods using four objects of the class. Now modify the Event and EventDemo classes as follows: Modify the method that sets the event number in the Event class so that if the argument passed to the method is not a four-character String that starts with a letter followed by three digits, then the event number is forced to A000. If the initial letter in the event number is not uppercase, force it to be so. Add a contact phone number field to the Event class. Add a set method for the contact phone number field in the Event class. Whether the user enters all digits or any combination of digits, spaces, dashes, dots, or parentheses for a phone number, store it as all digits. For example, if the user enters (920) 872-9182, store the phone number as 9208729182. If the user enters a number with fewer or more…arrow_forwardThe 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_forwardThis C# program assignment requires that you write and call two programmer defined methods as described below: Method #1 (MyAddress) – this programmer defined method should output your name and address in a mailing label format. This method does not require any parameters, and will not return any value. Method #2 (AddressOut) – this programmer defined method should have three string parameters (name, address, and city‐state‐zip) and should output the passed parameters in mailing label format. This method will not return any value. Your Main() method for this program should consist of two lines of code – calls to each of the methods. Here is an example of the code in my Main() method MyAddress(); AddressOut(“Tim Jones”, “123 Main St.”, “East Brunswick, NJ 08816”);arrow_forward

PC #2. Word Counter (page 608) Write a method that accepts a String object as an argument and returns the number of words it contains. For instance, if the argument is “Four score and seven years ago” the method should return the number 6. Demonstrate the method in a program that asks the user to input a string and then passes it to the method. The number of words in the string should be displayed on the screen.

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.

For instance, if the argument is "hello. my name is Joe. what is your name?" the method should return the string "Hello. My name is Joe. What is your name?" The application should let the user enter a string and then pass it to the method. The modified string should be displayed.arrow_forwardhandler: This method retrieves whatever the user has typed into the upper entry, converts it into an integer, calls the method getAge() to determine the equivalent cat age for the specified number of years, and places the cats's age into the lower entry. If the user enters something into the upper entry that cannot be evaluated as an integer or can be evaluated as an integer and is negative (e.g., less than zero), the handler displays a showinfo box with an appropriate message (title="Ooops!", message="The number of years is invalid.") and then clear() upper entry and lower entry instead of duplicating the code. A correct method must also call the getAge() method to obtain the cat's age. --------------------------------------------------------------------------- def getAge(self, years): if years <= 0: return 0 elif years == 1: return 15 else: return 24 + (year - 2) * 4 # Write this method def handler(self): pass def clear(self):…arrow_forward
- In python Add the following four methods to your Crew class: move(self, location): This takes in a location as a string, along with self, and attempts to move the crew member to the specified location. If location is one of the five valid location options ("Bridge", "Medbay", "Engine", "Lasers", or "Sleep Pods"), then this should change self.location to that new value. Otherwise, the function should print out the message: Not a valid location. repair(self, ship): first_aid(self, ship): fire_lasers(self, ship, target_ship, target_location): The above three methods represent tasks that a basic Crew member is not capable of (but one of its derived classes will be able to accomplish). So each of them should simply print out a message of the form: <Name> doesn't know how to do that. Examples: Copy the following if __name__ == "__main__" block into your hw12.py file, and comment out tests for parts of the class you haven’t implemented yet. if __name__ == '__main__': crew1…arrow_forwardProblem: An online grocery store sells items on a web page.

User specifies the weight amount or the quantity in his selection of items depending on its type. The price is computed as the product of the price per item or the price per weight and the weight or quantity are given by the user. Write an application that reads a user basket list and produces the bill receipt. Check the given samples of input/output in the figures below.
