### Question:
Range implements Serializable, HasIsConstrained { public boolean after(final long num) { return from != null && from.longValue() > num; } @JsonCreator  Range(@JsonProperty("from") final T from,
                 @JsonProperty("to") final T to,
                 @JsonProperty("matchNull") final boolean matchNull);  Range();  Range(final T from, final T to); static Range<T> of(final T from, final T to); static Range<T> from(final T from); static Range<T> to(final T to); boolean isMatchNull(); void setMatchNull(final boolean matchNull); boolean contains(final long num); boolean after(final long num); boolean before(final long num); T getFrom(); T getFromOrElse(final T other); T getTo(); T getToOrElse(final T other); @JsonIgnore boolean isBounded(); @JsonIgnore boolean isEmpty(); Number size(); @SuppressWarnings({"rawtypes", "unchecked"}) Range<T> union(final Range other); @JsonIgnore @Override boolean isConstrained(); @Override final boolean equals(final Object obj); boolean isMatch(final T num); @Override final int hashCode(); @Override String toString();  }### Answer:
@Test void after() { assertThat(Range.of(10L, 20L).after(9)).isTrue(); assertThat(Range.of(10L, 20L).after(10)).isFalse(); assertThat(Range.of(10L, 20L).after(15)).isFalse(); assertThat(Range.of(10L, 20L).after(19)).isFalse(); assertThat(Range.of(10L, 20L).after(20)).isFalse(); }
