  • Java focus question

    - by Albinoswordfish
    This may be a silly question I don't know. Is there a way to remove the highlighter to represent focus in a Java GUI? For example when you click on a button the text will have a slight rectangle around the text. Thank you

  • Java RegEx find, except when between quotes

    - by user1833511
    I need a Java RegEx to split, or find something in a string, but exclude stuff that's between double quotes. What I do now is this: String withoutQuotes = str.replaceAll("\\\".*?\\\"", "placeholder"); withoutQuotes = withoutQuotes.replaceAll(" ",""); but this doesn't work nice with indexOf, and I also need to be able to split, for example: String str = "hello;world;how;\"are;you?\"" String[] strArray = str.split(/*some regex*/); // strArray now contains: ["hello", "world", "how", "\"are you?\"] quotes are always balanced quotes can be escaped with \" Any help is appreciated

  • long polling netty nio framework java

    - by Alfred
    Hi, How can I do long-polling using netty framework? Say for example I fetch http://localhost/waitforx but waitforx is asynchronous because it has to wait for an event? Say for example it fetches something from a blocking queue(can only fetch when data in queue). When getting item from queue I would like to sent data back to client. Hopefully somebody can give me some tips how to do this. Many thanks

    - by rukoche
    User32 interface (platform library) is missing some WinAPI functions, so I tried extending it: package myapp import com.sun.jna.platform.win32.W32API public interface User32 extends com.sun.jna.platform.win32.User32 { myapp.User32 INSTANCE boolean IsWindow(W32API.HWND hWnd) } But then calling myapp.User32.INSTANCE.FindWindow(..) results in java.lang.NullPointerException: Cannot invoke method FindWindow() on null object

    - by Nik
    As the author has forgotten to add a detailed usage listing (or I can't find it), I wonder if anyone knows anything about the command-line options accepted by the FernFlower decompiler application. You can find an online version here: http://www.reversed-java.com/fernflower/ I'm trying to enable/disable all these flags that are present on that webpage. The actual command-line JAR can be found here: https://github.com/Bukkit/Bukkit-MinecraftServer Many thanks Nik

  • Naming convention when casually referring to methods in Java

    - by polygenelubricants
    Is there a Java convention to refer to methods, static and otherwise, any specific one or the whole overload, etc? e.g. String.valueOf - referring to all overloads of static valueOf String.valueOf(char) - specific overload, formal parameter name omittable? String.split - looks like a static method, but actually an instance method Maybe aString.split is the convention? String#split - I've seen this HTML anchor form too, which I guess is javadoc-influenced Is there an authoritative recommendation on how to clearly refer to these things?
