With commons/lang you can do this using StringUtils.join: You can’t really beat that for brevity. Update: Re-reading this answer, I would prefer the other answer regarding Guava’s Joiner now. In fact, these days I don’t go near apache commons. Another Update: Java 8 introduced the method String.join() While this isn’t as flexible as the Guava version, it’s handy when … Read more
It’s better to use either of the following: The first alternative should give you no result or one result, the second count should be zero or one. How old is the documentation you’re using? Although you’ve read good advice, most query optimizers in recent RDBMS’s optimize SELECT COUNT(*) anyway, so while there is a difference … Read more
One of the best pages describing image rotation algorithms I’ve found on the internet is tied to Dan Bloomberg’s excellent leptonica library. While the leptonica library itself is written in C and won’t help you, his page on image rotation algorithms: http://www.leptonica.org/rotation.html is definitely worth a read. You will most likely want to implement something … Read more
Some test results I’ve gotten a lot of good answers to this question–thanks folks–so I decided to run some tests and figure out which method is actually fastest. The five methods I tested are these: the “ContainsKey” method that I presented in the question the “TestForNull” method suggested by Aleksandar Dimitrov the “AtomicLong” method suggested … Read more
FetchTask directly fetches data, whereas Mapreduce will invoke a map reduce job Run code snippetExpand snippet Also there is another parameter hive.fetch.task.conversion.threshold which by default in 0.10-0.13 is -1 and >0.14 is 1G(1073741824) This indicates that, If table size is greater than 1G use Mapreduce instead of Fetch task more detail
I’ll do my best to explain it here on simple terms, but be warned that this topic takes my students a couple of months to finally grasp. You can find more information on the Chapter 2 of the Data Structures and Algorithms in Java book. There is no mechanical procedure that can be used to get the BigOh. As … Read more
Since this question is still getting a lot of attention, I decided to answer it by copying this answer from Code Review.SE: You’re following the same philosophy as the bubble sort, which is very, very, very slow. Have you tried this?: Sort your unordered array with quicksort. Quicksort is much faster than bubble sort (I know, you … Read more
If you use std::array instead of a built-in array (which you should), it becomes very simple. Copying an array is then the same as copying any other object.
Python includes a profiler called cProfile. It not only gives the total running time, but also times each function separately, and tells you how many times each function was called, making it easy to determine where you should make optimizations. You can call it from within your code, or from the interpreter, like this: Even more … Read more
