Scanner class allow the user to read input from command prompt. To store the data, an object of ArrayList is created, that will add the list elements using add() method. The method read() reads the string value from the console.We have used for loop to input 5 elements. Now to sort these elements, we have used Collections.sort() method that will sort the list elements alphabetically.
