### Question:
ObjectUtil { public static boolean noneNull(final Object... o1s) { return !anyNull(o1s); } private  ObjectUtil(); static boolean equalsValue(final Integer i1, final Integer i2); static boolean equalsValue(final BigDecimal bd1, final BigDecimal bd2); static boolean equalsValue(final Object o1, final Object o2); static boolean equalsAny(final Object o1, final Object... o2s); static boolean equalsAll(final Object o1, final Object... o2s); static boolean notEqualsAny(final Object o1, final Object... o2s); static boolean anyNull(final Object... o1s); static boolean allNull(final Object... o1s); static boolean atLeastOneNotNull(final Object... o1s); static boolean noneNull(final Object... o1s);  }### Answer:
@Test public void testNoneNull() { assertThat(ObjectUtil.noneNull()).isFalse(); assertThat(ObjectUtil.noneNull(null)).isFalse(); assertThat(ObjectUtil.noneNull(1)).isTrue(); assertThat(ObjectUtil.noneNull(1, 2)).isTrue(); assertThat(ObjectUtil.noneNull(1, 2, null)).isFalse(); assertThat(ObjectUtil.noneNull(null, 1, 2)).isFalse(); }
