java - returning specific values from a hashmap -

i have dictionary of terms dictonery/ab.txt , big text file dictonery/annotate.txt.

i want know dictionary terms in ab.txt in annotate.txt file.

here code far:

string filestring = new string(files.readallbytes(paths.get("dictonery/ab.txt")), standardcharsets.utf_8); map<string, string> map = new hashmap<string, string>(); string entirefiletext = new scanner(new file("dictonery/annotate.txt")).usedelimiter("\\a").next(); map.put(filestring, "m"); (string key : map.keyset()) { if(filestring.contains(key)) { system.out.print(key); } }

at moment whole dictionery returned. how can specific terms in annotator.txt file?

there's few things might help:

since don't need values in map, utilize set (specifically hashset). use scanner.next() read individual words instead of entire file @ once your check filestring.contains(key) pretty inefficient, , homecoming true partial matches (if dictionary has word "do", match "dog"). print matching words multiple times.

personally, create 2 sets, read both files same way, , calculate intersection. if want sorted output (probably not requirement, nice), create set iterate on treeset.

java hashmap

python - How to add an model instance to a django queryset? - it seems django queryset behaves somehow python list. but doesn't back upwards list's .append() method know. what want like: from my_django_app.models import mymodel queryset = mymodel.objects.none() queryset.append(mymodel.objects.first()) ## no list's .append() method! is there way add together model instance existing queryset? no. queryset representation of query - hence name - not arbitrary collection of instances. if need actual queryset rather list, seek accumulating ids of objects need , getting objects via __in query: list_of_ids = [] list_of_ids.append(my_id) ... queryset = mymodel.objects.filter(id__in=list_of_ids) this isn't efficient, though. python django
