Unit 7 Assignment Grading Information: This Program is due on Date Specified. Comments are REQUIRED; flow charts and pseudocode are NOT REQUIRED. Directions Points The files must be called (driver) (handles house variables and methods) Proper coding conventions required the first letter of the class start with a capital letter and the first letter of each additional word start with a capital letter. Only submit the .java files needed to make the program run. Do not submit the .class file or any other file. 5% Style Components Include properly formatted prologue, comments, indenting, and other style elements as shown in Chapter 2 starting page 64 and Appendix 5 page 881-892. 5% Topics covered in chapter Topics with * are covered in this assignment. Ensure you use every item listed below with an * in your completed assignment. *Relationships between reference variables and objects Reference assignment Memory space Equality of Objects Swap data in objects *Method call chaining *Object creating and initialization Calling one constructor from inside another Class variable usage Class methods Class constants Basic Requirements Write a driver and house class that gets input and using method call chaining creates 2 houses, imports the data from a text file, and outputs the results. Refer to chapter 3 on how to read in a file. LiFiUnit7.java Provide a driver class that demonstrates this house class. You the code below as the contents of you main method. Ensure you use the code provided exactly as given 20% inside your main method except for renaming your House class. Scanner stdIn = new Scanner(System.in); Scanner stdInFile = new Scanner(new File("LiFiUnit7HouseData.txt")); LiFiUnit7House_SU_2016 house1, house2; //New houses //Create house 1 using default constructor house1 = new LiFiUnit7House_SU_2016(); house1.print(); //print house 1 with default values String street, city, state, zipCode; int number; System.out.println("Importing Number."); number = stdInFile.nextInt(); stdInFile.nextLine(); System.out.println("Importing Street."); street = stdInFile.nextLine(); System.out.println("Importing City."); city = stdInFile.nextLine(); System.out.println("Importing State."); state = stdInFile.nextLine(); System.out.println("Importing ZipCode."); zipCode = stdInFile.nextLine(); System.out.println(); //use method call chaining to set values //and print results for house 1 house1.setNumber(number).setStreet(street) .setCity(city).setState(state) .setZipCode(zipCode).print(); System.out.println("Importing Number."); number = stdInFile.nextInt(); stdInFile.nextLine(); System.out.println("Importing Street."); street = stdInFile.nextLine(); System.out.println("Importing City."); city = stdInFile.nextLine(); System.out.println("Importing State."); state = stdInFile.nextLine(); System.out.println("Importing ZipCode."); zipCode = stdInFile.nextLine(); System.out.println(); //create house 2 using 5 parameter constructor house2 = new LiFiUnit7House_SU_2016(number, street, city, state, zipCode); //print house 2 house2.print(); This demonstration driver does not call all accessor and mutator methods but it is normal to create them regardless of an immediate use. They may be needed in the future. Sample output is provided below. Be sure to mimic it exactly except for values entered. LiFiUnit7House.java Write a House class called LiFiUnit7House.java that implements the following methods. setNumber receives the house number setStreet receives the street name setCity receives the city name setState receives the state name setZipCode receives the zip code Separate accessor methods for each instance variable utilized. 30% Method Call Chaining Pay attention to implement method call chaining as prescribed in the main method given. This is the main part of the program for this week. 40% NOTE: Complete your activity and submit it by clicking Submit Assignment Total Percentage 100% Data for Text File (name it LiFiUnit7House.txt) 8700 NW River Park Dr. Parkville MO 64152 1600 Pennsylvania Ave NW Washington DC 20500 Sample Your output for House 1 and House 2 should match the sample below.
