Question

Java

Description This project is designed to help you practice for the second midterm examination. First you will hand write the code for the project, just as you would do on the examination. Then you will take your hand written code and enter it into eclipse and debug/fix it. This should help you identify challenges that you have in hand writing code that could cause problems on the midterm on Wednesday Write a program that generates platitudes, by writing each of the methods on the following pages Platitudes are "A trite and obvious observation, in particular one that's expressed as if it were fresh and significant," at least according to http://grammar.about.com/od/pq/g/Platitude.htm The platitudes will be read in from a file of platitudes named "Quotes.txt". This file is available in the Project directory. To select a platitude, you will find one that contains a word the user gave or, if no such platitude exists, to choose one randomly from the platitudes in the file. The file contains no more than 1000 platitudes. The array that contains your quotes should be oversized You must write the methods exactly as they are given. You may not change the methods, parameters, or return type. You must use the methods you write in a) and b) in the main program in c) a) public static int readFile(Stringl] platitudes, String filename) This method reads in the file with the given name into the oversized array platitudes. The number of lines that were in the file are returned b) This method should determine whether the String word is contained anywhere in the list of platitudes (given as an oversize array). If the word is in one of the platitudes, that one should be returned. If the word is not in a platitude, a random platitude from the array should be returned There is a useful method, called contains, in the String class. This method returns true if the argument is in the String used to call the method, and false otherwise. It is used in code below String example-"ABC"; String test "AB" if (example.containstest)) System.out.printin(testis in " example) Will print out: "AB is in ABC" The method signature is: public static String findPlatitude(Stringll platitude, int size, String word) c) Write the main program using the methods in a) and b) The signature of the methods in a) and b) are below public static String findPlatitudelStringl platitude, int size, String word) public static int readFile(String] platitudes, String filename)

Answer 1

thanks for the question, here is the complete class wherein both the methods has been implemented, you need to update the file name that needs to be read and also the search word that needs to be searched . Rest everything has been implemented, the program at the end prints the platitude that contains the search word

Let me know for any questions or doubts. I have commented the important lines.

Do give a thumbs up !!
