Primitive Type Arithmetic Calculation
Consider the following method, which is intended to convert a given number of hours and minutes into a total number of seconds.
public static int convertToSeconds(int hours, int minutes) {
/* missing statement */
return totalSeconds;
}
For example, convertToSeconds(1, 30) should return 5400, and convertToSeconds(2, 15) should return 8100. Which of the following code segments can replace /* missing statement */ so that the method works as intended?
A
int totalSeconds = (hours + minutes) * 60;
B
int totalSeconds = Math.abs(hours * 60 - minutes) * 60;
C
int totalSeconds = hours * 60 * 60 + minutes * 60;
D
int totalSeconds = (int) (hours * minutes * 60);
