Write a program that includes a method that returns the sum of all the elements of an arraylist of integer objects. allow the user to enter the integers to be added to your arraylist from the console (max of 10 integers). test your program and display your integers and the sum results. write a program that include a method that returns the sum of all the elements of a linked list of integers. allow the user to enter the integers to be added to your linked list from the console (max of 10 integers). test your program and display your integers and the sum results.

Write a program that prints the day number of the year, given the date in the form month-day-year. for example, if the input is 1-1-2006, the day number is 1; if the input is 12-25-2006, the day number is 359. the program should check for a leap year. a year is a leap year if it is divisible by 4, but not divisible by 100. for example, 1992 and 2008 are divisible by 4, but not by 100. a year that is divisible by 100 is a leap year if it is also divisible by 400. for example, 1600 and 2000 are divisible by 400. however, 1800 is not a leap year because 1800 is not divisible by 400.
