I have a Java Client which sends UTF-8 strings to a C# TCP-Server, I'm using a DataOutputStream to send the strings. The code looks like this: public void sendUTF8String(String ar) { if (socket.isConnected()) { try { dataOutputStream.write(ar.getBytes(Charset.forName("UTF-8"))); dataOutputStream.flush(); } catch (IOException ...
In C as we know the size of data types (ex. int) can vary depending on compiler / hardware. But why the size of data types is constant in java language? why don't we have the flexibility for different data type size in java depending on compiler? ...
In Java, by using non-default system look and feel we will have different keymap. For example I'm using Mac OS X and use Substance look and feel (non-default system look and feel). The effect is I'm loosing my "meta" key for select all on text component In mac os x should be "meta + a", but using Substance we have to use "ctrl + a" (and...

I will be taking care of representing the resources but I don't want to reinvent the mapping and the URI transformations, if possible?! I need a simple support for parsing routes, such as: ...

I am trying to send a file (an image sent as a byte array) with the client and then the server should receive said byte array to make further use of it. However when I click on the "send" to send the image the file transfer starts (as I get a sentImage.jpg in my Desktop) but it gets stuck for some reason I can't figure out and the image ...
I'm trying to check spelling accuracy of text samples using the Stanford NLP. It's just a metric of the text, not a filter or anything, so if it's off by a bit it's fine, as long as the error is uniform. My first idea was to check if the word is known by the lexicon: private static LexicalizedParser lp = new LexicalizedParser("englishP...

Otherwise, assigned values may not be visible to other threads. In addition anything that manipulates pixels on screen should be run f...
