In the below map, I have to remove key and values if key contains "tmst"
Input Map:
{"sun":"test", "row_mod_tmst":"10:05:20", "when" :"yesterday"}
Output Map:
{"sun":"test", "when" :"yesterday"}
I have tried like below, It is not working
Map<String, Object> withoutTMST = map.entrySet().stream().filter(entry -> (!entry.getKey().endsWith("tmts"))).
collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));
Alex Somai :
I would just remove those entries from the map, instead of creating a new map object.
Collection#removeIf is a good candidate for this, applied on the map's entrySet().
As for the removal condition, I would use contains in conjunction with toLowerCase().
Here's the code for that:
map.entrySet().removeIf(entry -> entry.getKey().toLowerCase().contains("tmst"));
Input:
{ sun=test, row_mod_tmst=10:05:20, when=yesterday }
Output:
{ sun=test, when=yesterday }
