Answered 2020-Mar-29 at 11:01I just solved it .
Remember when i said that the text editor is unlicensed ?
Well , it seems like it has broken.
The above code was pasted from Sublime Text.
But,when i checked the java file in notepad++,the method didn't even existed !!!
So , I copied the above code,pasted in notepad++ , ran the program and it has started working now.
Sorry and thanks !
Please get your text editor licensed if you are working on a bigger project !
it just wasted by whole day to fix !

QUESTION
I am annotating an huge amount of Strings as CoreDocuments through Stanford Corenlp. StanfordCoreNLP pipelines have an internal feature for multithreaded annotating to optimize the process however as far as i can see CoreDocument objects cant use that feature in the version i run,- which is stanford-corenlp-full-2018-10-05.
Since I could not make Pipelines Annotate collections of CoreDocuments I instead tried to optimize the individual annotations by placing them inside multithreaded methods. I have no Issues with the multithreaded environment. I receive all results back as expected, my only drawback is the time consumption. I tried about 7 different implementation and these were the 3 fastest:

Determine sentences contain all of the words of a phrase
0: chris and jennifer had a fight this morning
1: chris went on a holiday
2: jennifer is in prisonQuery Phrases are
0: chris jennifer
1: jennifer
2: prisonGoal is to find indexes of the matching sentences for each query or -1 if there are no matching sentence exists. Order of words does not matter.
Output :
0
0 2
2
i.e. First query has matching words in sentence 0, second one in sentence 0 and 1. and so on.
Constraints
- n: number of sentences
- m: number of prases
- n, m < 10^4
- Number of words in any sentence or query phrase is in range [1-10]
- Each word has at most 11 chars
- No word appears in more than 10 sentences
- Each word consists of upper and lower case alphabet only
- Each word must match exactly - i.e. likes and like do not match.
Input Format:
3
chris and jennifer had a fight this morning
chris went on a holiday
jennifer is in prison
3
chris jennifer
jennifer
prison
each 3 represents number of sentences or queries.
The followings were what I tried...
1. My first solution :
- Make HashMap per each sentence
- For each splitted word in phrase :
2-1. check if all words exists in the sentence hashmap
2-2. If so store the index
2-3. If there is no matching sentences exist for all sentences, store -1. - Print result
let p = the largest number of words in a sentence
let k = the largest number of words in a query
Big O is O(npk)
ANSWER
Answered 2018-Oct-22 at 21:31Maintain a HashMap
that will map String
s to Set
. The idea is to keep track of what sentences a given word appears in. We use a set instead of an array in order to support computing the intersection of two sets efficiently.
For each input sentence:
- Tokenize it into words, and add the index of the current sentence to the Set corresponding to the current token.
For each query phrase:
- Tokenize it into words.
- Query for the Set of indices corresponding to each word
- Take the intersection of all of these sets.
Time Complexity: Given that there are 10 words in each sentence, the cost of building the HashMap is O(10N log N). The cost of each query is O(10 * log(N)).
QUESTION
Hello Everybody I am trying to open one popper at the time on click. I am surprised there is not an example of this on the React Material site. Right now I am trying to render multiple markers with their own popper. However, all of poppers are opening onClick here is my code. PS: I will attach a picture below to provide details of my problem.
...ANSWER
Answered 2019-Feb-24 at 16:40Did you notice you are taking a param id
in your handleClick
, but you are not using it?
You are creating an array of Popper
component. Each of which depends on the same state.open
to open and the same state.anchorEl
to hang around. So whenever you click on a single marker, all of them pops up and you are seeing the last one on top. Every time the last one remains on top, so it feels only one is getting popped up.
What you could do to fix this:
Make anchorEl
, open
, placement
each an array:

I was using Guava 17.0 with this
...ANSWER
Answered 2019-Jan-22 at 14:00See MapMakerMigration on Wiki:
All caching related methods on
MapMaker
have been deprecated in favor of similar methods inCacheBuilder
, and are scheduled for upcoming deletion. (...)Most
MapMaker
use cases should be migrated to eitherCacheBuilder
orAtomicLongMap
. Specifically, cases when MapMaker is used to construct maps withAtomicLong
values should generally be migrated toAtomicLongMap
. Other cases where MapMaker caching functionality is used (including all uses ofMapMaker.makeComputingMap(Function)
) should be migrated toCacheBuilder
.
So the question is: do you really need to use ConcurrentMap
interface? If yes, use asMap()
view, which for non-computing maps should have same functionality:
Returns a view of the entries stored in this cache as a thread-safe map. Modifications made to the map directly affect the cache.
In your case this would be:
QUESTION
I'm trying to make a simple map making function. I have a database with geographic coordinates ('latitude' and 'longitude'), places names ('feature_names) and the ISO-3166 country codes ('countrycodes'). Now I have gotten this to work with just querying the lat/long and having Folium make my map, but the problem with that is that, well, there are multiple Ottawas, Vancouvers, Londons, etc. in the world. Hence the introduction of the country code to try and narrow things down.
My issue is that I can't seem to get the SQL query to return anything. The code executes without throwing me an error, but does not return anything. TL;DR: How do I make multiple queries to my database?
...ANSWER
Answered 2018-Jul-09 at 14:55A database can be smarter than a simple flat list of rows. In particular, it can contain indexes to speedup queries. Without knowing if and how the database is indexed, it is not possible to optimize a query.
If your database contains indexes, you should not load its content in flat lists, but instead use direct queries.
That being said, you can retrieve more than one single column from a query, so IMHO the correct way to extract geographic coordinates from you table should be:
QUESTION
I'm attempting to create a turn based strategy game using a 3D HexGrid map, I've implemented dijkstra's algorithm but it doesn't run 100% efficiently and I can't work out why. I also attempted to implement A* but have had to stop as I can't work out how to properly implement it, so any help with that would also be massively appreciated.
My unit passes it's GameObject and the Vector3 of it's target to the generate path function and each Node in the graph list is populated with its x,y,z and all of it's neighbors.
The inefficiencies are such that when moving; in a -X direction when on an odd Z plane or in a +X when on an even Z plane, an extra step is made, shown in the screenshots. Another Inefficiency is that when moving in the Z plane an extra step is often taken as the code seems to prefer keeping it's X value the same for as long as possible before approaching on the Z plane. This is leading to the unit being 1 tile further from the goal when it starts it's Z movement than it would have been has it moved 1 X negatively to start with.
I'll add my path generation code, neighbor generation code and my node class code as well as screenshots of where the inefficiencies are occurring as I know my explanations are unclear at best. The neighbor code ensures that the highest adjacent tile is the one stored as the neighbor (it also has to search through types as i have a variety of tile types.
Thank you so much in advance, to anyone that might be able to offer some help or insight in to what is going wrong.
...ANSWER
Answered 2018-Jul-06 at 13:15You are using a List
instead of a priority queue, which is massively inefficient. Also, since your grid has a simple heuristic, you should consider using A* which will be much faster.
QUESTION
I'm using IntelliJ 14.1.7 and I have some weird behaviour that is popping up in one of my projects but not another. I can't for the life of me see the difference in configurations or how to fix it.
In both Project A and Project B I've added ojdbc8.jar
as a dependency via "Project Structure"->"Modules".
In Project A I go to "Edit Configurations" and select one of my run configs, and next to the "Add --classpath" checkbox the listing includes only the OJDBC path I added. When I check the box and run this the application runs fine.
In Project B I go to "Edit Configurations" and select one of my run configs, and next to the "Add --classpath" checkbox the listing includes a whole bunch of jars in my $HOME/.m2/repository
directory, followed by the OJDBC path I added. When I check the box and run this the application dies immediately with the error:
