Enhanced ER Model

The enhanced ER model is an abbreviation for Enhanced Entity-Relationship (EER) model. As you know, the entity-relationship (ER) model is a pictorial illustration of the relationship between various entities of a domain. In the case of a large amount of data with multiple interrelated entities, the ER diagrams become complex and tough to interpret. For such cases, the need for enhancement in the ER model was observed, and thus, the EER model was designed.

Question

100%

For this incomplete Reverse Engineering diagram, classes are shown. Use associations (uni- or bi-directional is ok) and generalization and if necessary compositions and aggregations. You can include constructors but do not have to.
In this level of abstraction, the relation between the classes should be shown through associations (do not include objects of a class type you have in your model as attribute in another class - use associations for that).

You should include: associations (aggregations/compositions if needed) with names and multiplicities, generalization, attributes (with visibility and attribute types), methods (with visibility, arguments and return types), types. Do not include roles and stereotypes.

Vowels and Consonants Create an application with a method that accepts a string as an argument and returns the number of vowels that the string contains. The application should have another method that accepts a string as an argument and returns the number of consonants that the string contains. The application should let the user enter a string, and should display the number of vowels and the number of consonants it contains.
C++HurdleWords The HurdleWords class is mostly provided to you. HurdleWords is constructed from two files in the data/ folder: ● valid_guesses.txt (all 5 letter guesses considered to be valid words to guess), and ● valid_hurdles.txt (all words that may be selected to be the secret Hurdle.) ● Note: you may edit both text files if you’d like to add custom words to your game. HurdleWords stores all potential valid Hurdles from valid_hurdles.txt into a vector of strings (valid_hurdles_), and all valid guesses from valid_guesses.txt into an unordered set of strings (valid_guesses_). A set is simply a data structure that contains no duplicates and allows for a speedy lookup to check if a given element exists within the set. Because there are over 10,000 valid guesses, we store them in an unordered set to leverage their speediness, as you will need to check if a user-submitted guess is considered valid (i.e. their guess is considered a valid guess in the dictionary). You are responsible for…
Word Separator Create an application that accepts as input a sentence in which all the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example, the string "StopAndSmellTheRoses." would be converted to "Stop and smell the roses."
Sentence Capitalizer Create an application with a method that accepts a string as an argument and returns a copy of the string with the first character of each sentence capitalized. 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.
PYTHON: In this assignment, you will use all of the graphics commands you have learned to create an animated scene. Your program should have a clear theme and tell a story. You may pick any school-appropriate theme that you like. The program must include a minimum of: 5 circles 5 polygons 5 line commands 2 for loops 1 global variable You may wish to use the standard code for simplegui graphics below: import simplegui def draw_handler(canvas): frame = simplegui.create_frame('Testing', 600, 600) frame.set_canvas_background("Black") frame.set_draw_handler(draw_handler) frame.start()
Pig Latin Create an application that accepts a sentence as input and converts each word to “Pig Latin.” In one version, to convert a word to Pig Latin you remove the first letter and place that letter at the end of the word. Then you append the string "ay" to the word. Here is an example: English: I SLEPT MOST OF THE NIGHT Pig Latin: IAY LEPTSAY OSTMAY FOAY HETAY IGHTNAY

Convert the UML class diagram above into a java code with the following conditions The methods in the Pet class are abstract. ownerName: String, colourofFeathers:String) + getColourOfFeathers (): String Create a class called test. The main() method in the test class should create three Cat objects and two Budgie objects. The main() method should also create indirectly an object of the Pet class. Demonstrate polymorphism in your test class. 2. Write a Java Code for a simple GUI program that creates a frame and changes the background to green. Examiner's Name: George Kodjo Anni
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.
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…

Word Counter Create an application with a method that accepts a string 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. The application should let the user enter a string, and then it should pass the string to the method. The number of words in the string should be displayed.
