Without multithreading, you're limited to one right after another. Theres nothing wrong with the code aside from the general limitation that the byte[] must obviously fit the heap and the inherent 2GB limit, but I assume you don't mind either. The perceived "slowness" probably comes from the URL's being http's which require a new network connection to retrieve each file the overhead is notable if there are many small files.
Aside from using multiple requests that is multithreading or working directly with http 1. Sotirios Yes, and I'm wondering if there's a way to make the above code more efficient so that even running one right after another, it goes faster than it does now.
I don't know if there's really anything I can do other than multithreading, but that's why I asked — DerStrom8. First find out where the bottle neck is. Is the network slow or the server or something else. Only when you know that you can think about optimizations. For example, if the network connection is slow, you will not have benefits from multithreading.
Thanks guys, That's what I was leaning towards. I am still working on putting together some performance tests to determine which parts are the slowest, but just wanted to see if there was an obvious improvement I could make to what I already have. Much appreciated! Either of these changes would spare you of storing external images on the local FS.
So from this point of view, the two answers are exactly the same. Show 1 more comment. Liviu T. Arthur bauer Arthur bauer 5 5 silver badges 11 11 bronze badges. Usually moot since there is usually no query. However, to get just the file, one should use url. Neither getFile or getPath does proper decoding, so the Paths. Oops sorry, I accidentally misread the code in your post and downvoted it because I thought it didn't match the java.
URL docs. If you edit your post, I'll be able to remove my downvote. Let me know if you do this. Fixed, I was able to edit it myself and remove the downvote.
I know they taught me this back in the day but I don't remember exactly how to do it now, any help is greatly appreciated. Use an URL instead of File for any access that is not on your local computer. Actually, URL is even more generally useful, also for local access use a file: URL , jar files, and about everything that one can retrieve somehow. The way above interprets the file in your platforms default encoding. If you want to use the encoding indicated by the server instead, you have to use a URLConnection and parse it's content type, like indicated in the answers to this question.
About your Error, make sure your file compiles without any errors - you need to handle the exceptions. Click the red messages given by your IDE, it should show you a recommendation how to fix it. Do not start a program which does not compile even if the IDE allows this. Using Apache Commons IO :. I did that in the following way for an image, you should be able to do it for text using similar steps.
