What is the return type of the setCycles method in the SineDraw class?

int
void
double[]
String

The correct answer is: void

The setCycles method in the SineDraw class does not return a value, but rather sets the value of the cycles variable to a given input. This means that the return type of the setCycles method is void, as it does not return any value. Option A, int, cannot be correct because the setCycles method does not return an integer value. Option C, double[], cannot be correct because the setCycles method does not return an array of double values. Option D, String, cannot be correct because the setCycles method does not return a String value.
