This game has 2 options for the user playing. Based on user input, the user can choose to either convert time, from seconds to hours, minutes, and seconds, or calculate the sum of all digits in an integer.
At the beginning of the game, the user will be prompted to input either 1 or 2, to indicate which option of the game they want to play. 1 will indicate converting time, and 2 will indicate calculating the sum of digits in an integer.
For converting time, the user will be prompted to input a number of seconds (as an int) and the program will call a method that will convert the seconds to time, in the format hours:minutes:seconds, and print the result. For example, if the user enters 6734, the program will print the time, 1:52:14. As another example, if the user enters 10,000, the program should print 2:46:39.
For calculating the sum of digits in an integer, the user will be prompted to input a number (as a non-negative int) and the program will call a method to calculate the sum of the digits in that number, and print the result. For example, if the user enters 321, the program will print the sum, 6, because the individual digits in the number add up to 6. 3 + 2 + 1 = 6.
Each method has been defined for you, but without the code. See the javadoc for each method for instructions on what the method is supposed to do and how to write the code. It should be clear enough. In some cases, we have provided hints to help you get started.
