World Series Champions If you have downloaded this book’s source code (the companion Web site is available at www.pearsonhighered.com/gaddis), you will find a file named WorldSeriesWinners.txt. This file contains a chronological list of the winning teams in the World Series from 1903 through 2009. (The first line in the file is the name of the team that won in 1903, and the last line is the name of the team that won in 2009. Note that the World Series was not played in 1904 or 1994, so those years are skipped in the file.) Write a program that lets the user enter the name of a team, and then displays the number of times that team has won the World Series in the time period from 1903 through 2009. Tip: Read the contents of the WorldSeriesWinners.txt file into an ArrayList. When the user enters the name of a team, the program should step through the ArrayList, counting the number of times the selected team appears You only need to submit the…arrow_forwardDebug thisarrow_forward

It will then read the file. Once the data is read, it should create an aircraft and then pass the vehicle to the addAircraft method. It should not allow any duplication of records. Be sure to handle all exceptions. o writeFile()-This method accepts a string that represents the name of the file to be written to and then writes the contents of the array to a file. This method should call a sort method to sort the amay before writing to it. sortArray()-This method returns a sorted array. The array is sorted by registration number.u addAircraft- This method accepts an aircraft and adds it to the fleet(the array only if it is not…arrow_forward
- Computer Science c sharp a program that will let you creat new cars, list all previous cars, update the other cars, and delete them. also be able to read from a text file and add to the text file. each car will have the following information VIN,model, make, color , and year. and store the information in a car object.arrow_forwardCharacter Analysis Create a source code text file and save it as named text.txt. Write a program that reads the file's contents and determines the following: - The number of uppercase letters in the file. - The number of lowercase letters in the file. - The number of digits in the file. - The number of whitespace characters in the file. * Note: Please be sure to use the Python program when creating the program.

- Problem: Write a Python program that reads from an input file named employees.txt some employee information and produces a salaries report on screen. The input file employees.txt has a number of data lines. Each data line in the input file contains information about one employee including: first name, last name, job code (an integer between 1 and 4), and the number of days worked. The following is an example of what the input file employees.txt can contain: Ali Al-Harthi 22 Laila Al-Busaidi 4 25 Salim Al-Hajri Badria Al-Sinani 2 21s 19 Abir Al-Hinai 1 15 Your program should produce a salaries report on screen using the format shown below.
