  • Resources for learning about Threading

    - by Incubuss
    I've spent the last year learning and using Java in university but we didn't do much (read: anything) in terms of Threading. We do some next year but I'm hopeful I'll be able to get a head start over the summer. What are the best resources for learning about and getting to grips with Threading?

  • Facebook Open Graph under a constrained application

    - by Hellnar
    Hello For an embedded system with internet (which works under a set-top box) I want to develop a primitive Facebook interface where users can type their user-names and password, showing their latest notificationsa, messages and other casual stuff via the recent Facebook Graph API. This middleware program uses Java ME to run programs (such as this simple facebook app) and it can connect to internet however it doesn't have a real web browser. Under this circumstance, is it possible to achieve such Facebook application? If you think so, what approach would you suggest ? Thanks

  • VB6's private static in C# ?

    - by blez
    In VB6 there are local static variables that keep their values after the exit of procedure. It's like using public vars but on local block. For example: sub count() static x as integer x = x + 1 end sub After 10 calls, x will be 10. I tried to search the same thing in .NET (and even Java) but there was none. Why? Does it break the OOP model in some way, and is there a way to emulate that.

  • How to set text above and below a JButton icon?

    - by mre
    I want to set text above and below a JButton's icon. At the moment, in order to achieve this, I override the layout manager and use three JLabel instances (i.e. 2 for text and 1 for the icon). But this seems like a dirty solution. Is there a more direct way of doing this? Note -I'm not looking for a multi-line solution, I'm looking for a multi-label solution. Although this article refers to it as a multi-line solution, it actually seems to refer to a multi-label solution. EXAMPLE import java.awt.Component; import java.awt.FlowLayout; import javax.swing.BoxLayout; import javax.swing.Icon; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.SwingUtilities; import javax.swing.UIManager; public final class JButtonDemo { public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable(){ @Override public void run() { createAndShowGUI(); } }); } private static void createAndShowGUI(){ final JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setLayout(new FlowLayout()); frame.add(new JMultiLabelButton()); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); } private static final class JMultiLabelButton extends JButton { private static final long serialVersionUID = 7650993517602360268L; public JMultiLabelButton() { super(); setLayout(new BoxLayout(this, BoxLayout.Y_AXIS)); add(new JCenterLabel("Top Label")); add(new JCenterLabel(UIManager.getIcon("OptionPane.informationIcon"))); add(new JCenterLabel("Bottom Label")); } } private static final class JCenterLabel extends JLabel { private static final long serialVersionUID = 5502066664726732298L; public JCenterLabel(final String s) { super(s); setAlignmentX(Component.CENTER_ALIGNMENT); } public JCenterLabel(final Icon i) { super(i); setAlignmentX(Component.CENTER_ALIGNMENT); } } }

  • Usecase for Workflow Engine

    - by Icarus
    Hi, We have an issue where a Database table has to be updated on the status for a particular entity. Presently, its all Java code with a lot of if conditions and an update to the status. I was thinking along lines of using a Workflow engine since there can be multiple flows in future. Is it an overkill to use a Workflow Engine here... where do you draw the line ?

  • Parse URLs of major video streaming sites and generate appropriate code for embedding.

    - by Markus Lux
    Posting a video on tumblr.com allows you to just paste the URL of the video on youtube, vimeo, whatever and tumblr automatically does the embedding for you. I assume that this would be nothing more than a mapping between an URL-regex and the belonging HTML construct for embedding the video. Or it is just parsing the response of the URL and getting the construct from there. Is there already any utility, preferably in Java, for doing this? If not, how would you do it?

  • Struts2 converting empty string parameter to an "int"

    - by Kyle Partridge
    How does one convert an empty string to an int using Struts2. When the application encounters this parameter with no value, like from an empty text field, it throws the following exception. java.lang.NoSuchMethodException: com.XXXXXXXXXXXX.setID([Ljava.lang.String;) Where ID is an integer, and the URL is: Something.action?ID=&other=rawr Is there a way to do this without using an Integer (class)? Do I have to write a type converter?

  • What is the best way to use whitespace while programming?

    - by Emmanuel Smith
    I'm fairly new to programming and from learning I have seen different ways of formatting code, comments, etc; and have been recommended on different techniques. I mostly program in C#, C++, and Java so I want to know what is the the best way to layout code so that if other people where to go through it, they would be impressed by how simple and easy to understand it is. I would like to know the same thing for commenting as well.

  • Does a HashMap retain the order of its elements on the next read if it is constructed as a LinkedHas

    - by javanix
    Suppose I have a Java method that returns a HashMap object. Because a LinkedHashMap is a subclass of HashMap, I can return a LinkedHashMap from this method just fine. On the next "read" action (no adding/removing/modifying of K/V pairs), would iterating over the keys of the resulting method (which returns a HashMap) go in the same order as the originating LinkedHashMap, even though the HashMap lacks the key links?

    I want to make an Application that uses RxTx version 2.2pre2 to work with Serial Ports. What are the Licence restrictions, since it is an "LGPL v 2.1 + Linking Over Controlled Interface" licenced library if I don't use the Sun's javax.comm.* interface, but the RxTx's own gnu.io.* when importing into Java Files?
