Question
Please answer in Java code
Program #2 Use the template Final Exam2.java to write your code. In your Main method, ask the user to enter a list of numbers. Use an ArrayList<Integer> to store these numbers. The user should be able to enter as many numbers as they want. The user will indicate they are done entering numbers by hitting the enter key without entering any data. The user input does NOT need to be validated. You can assume the user will only enter whole numbers (integers). Write two methods: addNumbers and largestNumber. You will pass the ArrayList of numbers to each method and each method must return the result back to main(). The use of global variables is NOT allowed. Print out the results of each method in main(). Important Notes: . addNumbers: This method accepts one argument of datatype ArrayList<Integer> and returns an int. It should add all the numbers in the array and return the total. You MUST figure out how to add up the numbers in the ArrayList on your own using a loop and the + operator. You may NOT use the built-in Java sum() method. • largestNumber: This method accepts one argument of datatype ArrayList<Integer> and returns an int. It should return the largest number in the ArrayList. You must figure out how to find the largest number in the ArrayList on your own. You may NOT use the built-in Java max() method. Example Run: In this program, you will ask the user to enter a list of numbers. The program will then find the sum of the numbers and determine which of the numbers is the largest. Please enter a number (or just hit enter to finish): 5 Please enter a number (or just hit enter to finish): 10 Please enter a number (or just hit enter to finish): 15 Please enter a number (or just hit enter to finish): 20 Please enter a number (or just hit enter to finish): 5 Please enter a number (or just hit enter to finish): The sum of the list of numbers is: 55. The largest number in the list is: 20.
