1. (25 points) For this question, first download the file called campers.txt and add it to your project as shown in class. Then write a program that does the following: 1.1. Open the file provided called campers.txt for input. Create 2 ArrayLists. The first will hold the student name which is a String and the second ArrayList will hold the camper age which is an int Use a while loop to input 2 pieces of data at a time from the file (Open campers.txt to see how it's formatted). Each line represents a single camper. Loop should end when there are no more lines in the file Add the camper age to the ArrayList holding ages Add the camper name to the ArrayList holding names 1.2. After you fall out of the while loop - close the file • Output a string to indicate what each column holds (Name Age) Use a loop to print out the information for each student on a single line from the two ArrayLists Example Output Name Age Masarra 10 Abbas 11 1.3. After you fall out of the for loop use another loop to loop through all the ages stored in the camper age ArrayList - Sum up the ages When the loop finishes print out average age of the campers with precision of 1 as shown below: Average age is 12.5 2. (25 points) Modify the BookStore and Book Search Engine classes explained in the class to include the following additional methods and test them: a) A method returning the book with the lowest price in the library. b) A method searching the library for Books of a given author and returning an ArrayList of such Books c) A method returning an ArrayList of Books whose price is less than a given number.
Style Use white space (Indentation, blank lines) to show the program structure. All variable and constant names will be meaningful and will follow naming conventions. Include all variable declarations and add a comment next to each variable as to its purpose. You will lose points if you have not added comments. On top of each program should have the following comments: Name: * Date: * Question number: * Description: Deliverables You create a program for each question then compress your projects all in a zip file with your lastname and homework number (Lastname_HW#) and submit the zip file on Moodle. Getting ready to demo your lab to your lab mentor The interview is 40% of your lab grade. Make sure to be prepared for your mentor's questions about your program. When it is your tum to explain your lab to your lab mentor follow these steps, make sure that your lab mentor sees the following steps: 1. Log on to Moodle. 2. Find your submission link for this lab. 3. Download your Lab on your computer 4. Find your lab wherever you downloaded. 5. Make sure to Unzip, (or extract) your folder 6. Open the solution file to demo your lab. You must follow these steps each time you are being graded for your lab. Your lab mentor must confirm that you downloaded what was submitted on Moodle. You should be graded on what was uploaded on Moodle not on a local copy obtained from your C drive or external drives (i.e., с memory sticks).
