Define a method called printEven that receives an input file name as parameter, reads the incoming integer values from the file, and displays the result horizontally. Assume that the necessary Java libraries are imported. Example: If the input file contains the values 5 8 2 12 45 17 9 14 3, printEven should display the result as follows: 8 2 12 14 Please use java. Thanks

Create a file named Question.py and then create a class on it named Question. A Question object will contain information about a trivia question. It should have the following: A constructor, with the following parameters: 1 string to be the question itself (for example: "When was Cypress College Founded?"). A list of four strings, each a possible answer to the question (only one of them should be correct) An integer named 'answer': the index in the list of the correct answer. Example: if the third answer in the answer list is the correct one, the client should pass 2 to this parameter to signify the correct answer is in index 2. Overload the __str__ method. It should return a string made up of the question and the four possible answers. A ‘guess’ method, with an integer parameter. If the 'answer' attribute matches the int passed to 'guess', return True. Otherwise, False On Main.py, in your main function, create a list and add four Question objects to it. You may give them with...

In java Browse Project Gutenberg (https://www.gutenberg.org/) for plain text versions of one or more works of literature of your choosing. Write a program that repeatedly searches a file for a target word or phrase.• Allow the user to supply the name of the file to search by means of a command-line argument; if the user does not supply a command line argument, ask for a file name interactively.• You may use either an array or an ArrayList to store each line in the file; but if you use an array, you’ll have to determine the array size (number of lines) before allocating the array. There are several ways to do this.• Report how many lines were read from the file.• Search for either individual words or phrases (Hint: use the .contains method, it’ll work for either a word or a phrase)• Show both the line number and the line itself for each line that contains the search target entered by the user (you may count the first line in the file as line 0).• If a search word is part of a larger...

Write a static method named fixSpacing that accepts a Scanner representing a file as a parameter and writes that file's text to the console, with multiple spaces or tabs reduced to single spaces between words that appear on the same line. For example, if the input file contains the following text, four score and seven years ago our fathers brought forth on this continent a new nation then your method should produce the following output: four score and seven years ago our fathers brought forth on this continent a new nation

In Java I need to design an ESP Game: Design a program to test your extrasensory perception. The program will randomly pick a card (you could consider only the card suit, for example [Hearts, Diamonds, Clubs, Spades]. ) Prompt the user to enter a suit, then display whether the user guessed correctly. ESP Game Outcomes: Modify your ESP game to write the outcome of a game to a file. Allow the user to play the ESP game multiple times, writing each outcome to a file. Then, determine the number of times the user guessed correctly reading from the file. Please include flowcharts and/or class diagrams
