response.setPeopleHealth(new ArrayList<String>() {{
for(HealthEnum e :HealthEnum.values()) {
add(e.getValue());
}
}})
sonarlint gives warning for this.
I tried to convert to singletone but it does not work with for, because it cant be added like arraylist.
Can i use lambda or stream?
For starters stop using the famous anti-pattern of new ArrayList<String>() {{..., than think about your problem to begin with, you have a array - need a List, thus:
List<String> list = Arrays.stream(HealthEnum.values())
.map(HealthEnum::getValue)
.collect(Collectors.toCollection(ArrayList::new));
and pass this ArrayList where you want to, like:
response.setPeopleHealth(list);
