Fleet class: Instance Variables An array that stores Aircraft that represents Delta Airlines entire fleet A variable that represents the count for the number of aircraft in the fleet Methods: o Constructor-One constructor that instantiates the array and sets the count to aero readFile()-This method accepts a string that represents the name of the file to be read. 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…

Strings and string manipulation Part A: Building upon an Existing Solution Redesign the solution in the following manner. Ask the user for their name and their email addresses before you display the results of the conversions. When the user enters their email address search the string for the @ symbol. If the symbol is not found, ask the user to re-enter their email address till they get it right. When you display the conversion output to the user, you must include the user’s name in the output. Part B: Write Something New! Write a complete and syntactically correct Python program to solve the following problem: Input a date in numeric format from the user e.g. mm/dd/yy. Examine the month entered by the user, if it is larger than 12 or smaller than 1, issue an error message and ask for input again. Perform similar validation tests for the date and year. Year must be 2015. (Any other year is invalid). In addition, the year must only be two digits long.. Once all input has been…
