### Question:
BigDecimalUtils { public static BigDecimal valueOf(int number) { return 0 <= number && number < NUMBERS.length ? NUMBERS[number] : BigDecimal.valueOf(number); }  static BigDecimal valueOf(int number);  }### Answer:
@Test public void test() { assertThat(BigDecimalUtils.valueOf(0).intValue()).isEqualTo(0); assertThat(BigDecimalUtils.valueOf(100).intValue()).isEqualTo(100); assertThat(BigDecimalUtils.valueOf(1000).intValue()).isEqualTo(1000); }
