  • Java JFrame EventQueue

    - by asmo
    In Java, to create and show a new JFrame, I simply do this: public static void main(String[] args) { new JFrame().setVisible(true); } However, I saw many people doing it like this: public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { new JFrame().setVisible(true); } }); } Why? Are there any advantages?

    - 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 unload static fields

    - by Alina Danila
    I have a java class that uses complex static fields which need special operations as close() so that they are safely cleaned by GC. For the initialization of static fields I use the static block. But I don't now how to unload the static field safely, so that I can call the close() method before the field is cleaned up by GC. Is there any way to unload a static field, similar to the static initialization block?

  • Error when using Java String split

    - by Dan Howard
    HI All, I've been using the basic split for a while - where I just parse out a string into an array based on a simple token like " " or ",". So of course a customer tries this: \\.br\ which fails miserably. I need to parse to an array of lines. The string for example looks like this: "LINE 1\\.br\\LINE 2\\.br\\LINE 3\\.br\\LINE 4\\.br\\" and this fails with java.util.regex.PatternSyntaxException: Unexpected internal error. Any ideas?
