### Question:
MathUtils { public static double divide(double dividend, double divisor) { return divisor == 0.0 ? 0.0 : dividend / divisor; }  static double divide(double dividend, double divisor); static long increment(long l); static double[] max(double[] d1, double[] d2); static long multiply(long factor1, long factor2); static int roundToInt(double d);  }### Answer:
@Test public void testDivide() { assertThat(MathUtils.divide(8.0, 2.0)).isEqualTo(4.0); assertThat(MathUtils.divide(0.0, 2.0)).isEqualTo(0.0); assertThat(MathUtils.divide(8.0, 0.0)).isEqualTo(0.0); }
