Primitive Type Arithmetic Calculation
Which of the following statements can replace the /* missing statement */ so that convertToSeconds works as intended?
Consider the method convertToSeconds, which is intended to calculate the total time in seconds for a given number of hours and minutes.
For example, the following scenarios demonstrate the expected behavior of convertToSeconds:
convertToSeconds(1, 30) = 5400
convertToSeconds(2, 15) = 8100
The current implementation of convertToSeconds is incomplete:
public static int convertToSeconds(int hours, int minutes) {
/* missing statement */
return totalSeconds;
}
Which of the following statements can replace the /* missing statement */ so that convertToSeconds 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);
