Lab Assignment 21_1 (Sets)

COSC 2436 Lab Assignment 21_1 (Sets) NOTE: Your program should be your own work and not a copy of anyone else’s code. Copied code will not earn any points. (Keeping programs unique should not be too hard since you are naming the variables and functions yourself.) Don’t forget to add labels before everything you print. 1. Write a program named Lab21_1A that will create a set of grocery items and use set operations to see if recipes can be made from those items.  Create a HashSet of Strings that will hold items you just bought from the grocery store  Fill this set from the input file Lab21_1A1.txt  Create a second HashSet of Strings of ingredients for your first recipe and fill it from input file Lab21_1A2.txt  Create a third HashSet of Strings of ingredients for your second recipe and fill it from the input file Lab21_1A3.txt  Call your method sending the grocery set and the first recipe set  Call your method sending the grocery set and the second recipe set  Print your remaining grocery set  Write a void method that will accept the grocery HashSet and a recipe HashSet as parameters. It should do the following: o Using set operations, determine if the grocery item set contains everything in the recipe set (so you can make the recipe) o If it does:  Print a statement that says the dish was made  Print the ingredients in the recipe set  Remove all the items in this recipe set from the grocery set (because you used them to make dinner.) o If it does not contain the recipe set:  Print a statement saying that instead  Print the recipe ingredients that are missing from the grocery set 2. Write a program named Lab21_1B .  Create a secondary class named House . This class should have: o Private instance variables to hold the address (String), number of bedrooms (int) and square footage (int). o A constructor that receives a parameter matching each of the instance variables and fills them in. o An int method that returns the square footage of the house o A toString method that returns a string with all the instance variables and labels  Write a MyComparator class that uses the square footage in each House object to compare objects. If the first house has larger square footage, return a 1; if it has smaller return a -1; equal returns a 0.  In the (main class) main method: o Create a TreeSet of House objects.
