get(double) insteadnull if this map contains no mapping for the key.
More formally, if this map contains a mapping from a key
k to a value v such that (key==null ? k==null :
key.equals(k)), then this method returns v; otherwise
it returns null. (There can be at most one such mapping.)
If this map permits null values, then a return value of
null does not necessarily indicate that the map
contains no mapping for the key; it's also possible that the map
explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.

Long compute(Double key,
@Nonnull
java.util.function.BiFunction<? super Double,? super Long,? extends Long> remappingFunction)
compute(double, DoubleLongToLongFunction) insteadnull if there is no current mapping). For
example, to either create or append a String msg to a value
mapping:
map.compute(key, (k, v) -> (v == null) ? msg : v.concat(msg))
(Method merge() is often simpler to use for such purposes.)
If the function returns null, the mapping is removed (or
remains absent if initially absent). If the function itself throws an
(unchecked) exception, the exception is rethrown, and the current mapping
is left unchanged.

java.util.function.Function<? super Double,? extends Long> mappingFunction)
computeIfAbsent(double, DoubleToLongFunction) insteadnull), attempts to compute its value using the given mapping
function and enters it into this map unless null.
If the function returns null no mapping is recorded. If
the function itself throws an (unchecked) exception, the
exception is rethrown, and no mapping is recorded. The most
common usage is to construct a new object serving as an initial
mapped value or memoized result, as in:
map.computeIfAbsent(key, k -> new Value(f(k)));
Or to implement a multi-value map, Map<K,Collection<V>>,
supporting multiple values per key:
map.computeIfAbsent(key, k -> new HashSet<V>()).add(v);

If this map permits null values, then a return value of null does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to null.
