Maps and sets of given size after Java 19

[snago]

Java 19 introduced new static methods for creating maps and sets so that this (using Maps from Guava)

Map<String, String> map = Maps.newLinkedHashMapWithExpectedSize(numMappings);

can be replaced with

Map<String, String> map = LinkedHashMap.newLinkedHashMap(numMappings);

and similar for HashMap, HashSet, etc.

There's probably some similar Apache Commons methods that can be replaced as well.

Hi! Thanks for adding this @gaul!

The suggested replacements are slightly wrong though for HashMap and HashSet.
The current suggested replacement, java.util.HashMap<>(int), will create a HashMap that can fit 75% of the given size before it is resized. The correct replacement is java.util.HashMap.<>newHashMap(int).
Similar for HashSet, it should be java.util.HashSet.<>newHashSet(int), not java.util.HashSet<>(int).

I could create a PR if you want me to.

Please submit a PR to fix this!
