1a. Write a method called totalHours that takes three integer arguments (number of weeks, number of days, number of hours) and returns the total integer hours represented by the weeks, days and hours. No error checking on arguments is needed.

1b. Write a method totalDays that takes three integer arguments (number of weeks, number of days, number of hours) and returns the total real number days represented by the weeks, days and hours. No error checking on arguments is needed.

1c. Write a code segment to prompt the user to input three integers (number of weeks, number of days, number of hours) and then read the three integers from the console. Then if all three integers are non-negative, call your totalHours method and totalDays method and output the result from each. If any of the three integers input are negative, output an error message. You can assume your totalHours and totalDays methods are both in the same class as the code segment you write.

import java.util.Scanner;

Scanner in = new Scanner(System.in);

int weeks, days, hours;

System.out.println("Enter three integers, weeks, days and hours: ");
