### Question:
ObjectUtil { public static boolean notEqualsAny(final Object o1, final Object... o2s) { return !equalsAny(o1, o2s); } 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 testNotEqualsAny() { assertThat(ObjectUtil.notEqualsAny((Object) null)).isTrue(); assertThat(ObjectUtil.notEqualsAny("ABC")).isTrue(); assertThat(ObjectUtil.notEqualsAny((Object) null, null)).isFalse(); assertThat(ObjectUtil.notEqualsAny((Object) null, "ABC")).isTrue(); assertThat(ObjectUtil.notEqualsAny((Object) null, "ABS", null)).isFalse(); assertThat(ObjectUtil.notEqualsAny("ABC", "ABS", null)).isTrue(); assertThat(ObjectUtil.notEqualsAny("ABC", "ABS", "ABC", null)).isFalse(); }
