QUESTION
Using Java 8 streams, I want to find an actor who acted in max number of movies in a single year.
List of Movie(s): ...ANSWER
Answered 2022-Mar-11 at 22:52To achieve that, you can group the movies by year and by actor's name creating a nested map. And then process its entries.
It can be done with Collectors.groupingBy(). You need to pass as the first argument a function (Movie::getYear) that extracts a year, and that will be the key of the map.
As a downstream collector of the groupingBy you need to apply flatMapping to extract actors from a movie object. Note, flatMapping expect as an argument a function takes a stream element (movie object) and returns a Stream (of actor's names).
And then a downstream collector of the flatMapping you need to apply groupingBy again to create a nested map that will group movies by actor. Since only a number of movies is needed, counting() has to be used as a downstream collector to reduce movie objects mapped to each actor to a number of these objects.
With that will be created an intermediate map of type Map> that represent the total count of movies by actor for each year.
The next step is to create a stream over the entry set and flatten the nested map (count of movies by actor) by wrapping every entry in the map with a new composed entry of type Map.Entry> that will contain a year, actor's name and a count.
And the last step is to find the entry with the maximum count.
For that operationmax() has to applied on the stream. It expects a Comparator and returns a result wrapped by an Optional. I assume that resume is expected to be present, therefore the code below is a fail-fast implementation that will raise a NuSuchElementExeption in case if the stream source is empty (no result will be found).
Comparator is defined by using the static method comparingLong(). It will produce a comparator based on the count of movies.

ANSWER
Answered 2022-Mar-11 at 07:13One of the golden rules of tool customization is to only put stuff you understand in your config. The first step toward that understanding is to read (not skim) the documentation for any option or command you plan to add and then, armed with that newfound knowledge, ponder the pros and cons of doing so.
:help 'paste' is a very powerful option with many explicitly documented side effects, such as:
QUESTION
I am working on a project where I am using a shape file to make a choropleth map of the United States. To do this, I downloaded the standard shape file here from the US Census Bureau. After a little bit of cleaning up (there were some extraneous island territories which I removed by changing the plot's axis limits), I was able to get the contiguous states to fit neatly within the bounds of the matplotlib figure. For reference, please see Edit 4 below.
Edit 1: I am using the cb_2018_us_state_500k.zip [3.2 MB] shape file.
The only problem now is that by setting axis limits I now am no longer able to view Alaska and Hawaii (as these are obviously cut out by restricting the axis limits). I would now like to add both of these polygons back in my map but now towards the lower part of the plot figure (the treatment that is given by most other maps of this type) despite its geographical inaccuracy.
To put this more concretely, I am interested in selecting the polygon shapes representing Alaska and Hawaii and moving them to the lower left hand side of my figure. Is this something that would be possible?
I can create a Boolean mask using:

Answered 2021-Sep-22 at 17:25You could do something like this. You will have to find the right offsets to position Alaska where you want it to be exactly.
Now, you have the following dataframe:

Answered 2022-Feb-24 at 13:55Sure, you can parse and modify any JSON object in memory, but that has nothing to do with Spark. Related: What JSON library to use in Scala?
Any modifications you make wouldn't be persisted within the execution plan itself.

My problem is pretty simple but I want your advice on the matter! I have an excel document that contains 2 sheets... The first sheet look like this :
...ANSWER
Answered 2022-Jan-05 at 19:50First of all, assuming your data is in excell file, you should be able to read that. Install openpyxl:
pip install openpyxl
Now Here is my solution to print similar values in console.
I assume that in Sheet2, all names are in this format:
last_name, first_name
and in Sheet1, all names are in this format:
first_name last_name
So here is a pythonic solution to do what you want:

Install murphy
You can use murphy like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the murphy component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
