Please use java only. In this assignment, you will implement a simple game in a class called SimpleGame. 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 an 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. There are 2 methods that need to be implemented in the SimpleGame class: ● convertTime(int seconds) - Method that converts a given number of seconds to time in the format hours:minutes:seconds. ● digitsSum(int input) - Method that adds all the digits in a given non-negative integer. 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 and example method calls to help you get started. For example, we have defined a “convertTime” method for you (see below) which converts a given seconds value to time. For now, the method returns a null value as a placeholder. Read the javadoc, which explains what the method is supposed to do. Then write your code where it says “// TODO” to implement the method and replace the placeholder. You’ll do this for each method in the program. /** * Write a method to convert the given seconds to hours:minutes:seconds. * @param seconds to convert * @return string for the converted seconds in the format: 23:59:59 * * Example(s): * - If input seconds is 1432, print and return output in the format: 0:23:52 */ public String convertTime(int seconds){ // TODO: Your code goes here return null; } We’ll run Java tests against your program to test whether each method implementation is correct and whether you have considered enough cases. Examples of cases have been provided in the javadocs. The main method has not been completely implemented for you (see example below). You’ll need to write code (where it says “// TODO”) to use it to run and interact with your program, and to see if your methods are working as expected. Spend some time on testing. public static void main(String[] args) { // Create an instance of the SimpleGame class. // TODO: Your code goes here Scanner sc = new Scanner(System.in); // Ask the user which game to play. // Then ask the user for input and pass the value to the corresponding method. // If the user enters 1, ask for an integer to convert and call the convertTime method. // If the user enters 2, ask for an integer and call the digitsSum method. // TODO: Your code goes here sc.close(); } Tips for this Assignment In this assignment, some tips are given as follows: ● Modulus operation in Java: “%” is the modulus operator in Java. It returns the remainder, after division. For example: int result1 = 4 % 2; //result1 is 0 int result2 = 1000 % 90; //result2 is 10 ● int to String conversion in Java: There are multiple ways to convert an int to a String. ○ Use “Integer.toString(int)” For example: int num = 9; String str = Integer.toString(num); //str is “9” ○ Use “String.valueOf(int)” For example: int num = 9; String str = String.valueOf(num); //str is “9” ● String to int conversion in Java: ○ Use “Integer.parseInt(str)” For example: String str="0"; int num = Integer.parseInt(str); //num is 0 ● Getting a specific char in a String by index in Java: ○ Use “charAt(int)” For example: String str = "cit"; char firstChar = str.charAt(0); //firstChar is ‘

“%” is the modulus operator in Java. It returns the remainder, after division. For example:

○ Use “Integer.toString(int)” For example:
int num = 9;
String str = Integer.toString(num); //str is “9”
○ Use “String.valueOf(int)” For example:
int num = 9;
String str = String.valueOf(num); //str is “9”
● String to int conversion in Java:
○ Use “Integer.parseInt(str)”
For example:
String str="0";

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

At the beginning of the game, the user will be prompted to input either 1 or 2, to 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

and print the result. For example, if the user enters 321, the program will print the sum, 6.

Tips for this Assignment
In this assignment, some tips are given as follows:
Modulus operation in Java:
"%" is the modulus operator in Java. It returns the remainder, after division.
For example:
int result1 = 4 % 2; //resultl is 0
int result2 = 1000 % 90; //result2 is 10
• int to String conversion in Java:
There are multiple ways to convert an int to a String.
Use "Integer.toString(int)"
For example:
int num = 9;
String str = Integer.toString (num); //str is "9"
Use "String.valueOf(int)"
For example:
int num = 9;
String str = String.valueOf(num); //str is "9"
String to int conversion in Java:
Use "Integer.parselnt(str)"
For example:
String str="0";
int num = Integer.parseInt (str); //num is 0
Getting a specific char in a String by index in Java:
Use "charAt(int)"
For example:
String str = "cit";
char firstChar = str.charAt (0); //firstChar is 'c'
