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.

the iterator's own remove operation), the results of
the iteration are undefined. The set supports element removal,

Float compute(Long key,
@Nonnull
java.util.function.BiFunction<? super Long,? super Float,? extends Float> remappingFunction)
compute(long, LongFloatToFloatFunction) 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.

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);

For example, to either create or append a String msg to a

Returns the value to which this map previously associated the key, or null if the map contained no mapping for the key.
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.
The map will not contain a mapping for the specified key once the call returns.
