java-5

I have a JOptionPane with a custom message panel in it, in an application targeted for Java 1.5. The panel contains, among other things, a JTextField. Every 20 invocations or so, nothing in the dialog gets painted (not even the OK/Cancel buttons). If I drag the dialog off the screen and back again to force a repaint, the components are visible as expected, and apart from the painting problem, the components respond fine. Here is the smallest example I could get to exhibit this bug: public class BugTest { public static void main(String args[]) { SwingUtilities.invokeLater(new Runnable() {

Are there any solutions or tools that transform java 5 code that uses all the new java 5 features(generics, autoboxing, varargs, static imports) into code that can run on a J2ME device? I am particularly interested in handling generics - the other features are nice to have but not mandatory. I need source code as the result of this conversion as this will be compiled using a custom compiler. (I cannot use bytecode manipulation(ala retroweaver)) Compiling with the regular javac and targeting an older JVM will give you proper bytecode for generics at least. If you really need source it's

My issue is fairly straightforward. My program requires immediate notification if a network connection is lost. I'm using Java 5, so I'm unable to use the very handy features of NetworkInterface . Currently I have two different methods of checking for a network connection: (try..catches removed) Method One: URL url = new URL("http://www.google.com"); HttpURLConnection urlConnect = (HttpURLConnection) url.openConnection(); // trying to retrieve data from the source. If offline, this line will fail: Object objData = urlConnect.getContent(); return true; Method 2: Socket socket = new Socket("www

What is the easiest way to iterate over all the key/value pairs of a java.util.Map in Java 5 and higher? Assuming K is your key type and V is your value type: for (Map.Entry<K,V> entry : map.entrySet()) { K key = entry.getKey(); V value = entry.getValue(); // do stuff } 来源： https://stackoverflow.com/questions/585654/what-is-the-easiest-way-to-iterate-over-all-the-key-value-pairs-of-a-java-util-m

I know similar questions have been asked many times befor, but I think this one slitly different :) I'm writing a maven report plugin which will send emails to a list of users. I now have the problem, that the code seems to be working fine when I run it with java5, but failes with java6. Actualy the plugin is writen in Groovy and uses the commons-email utilities to send a html message: HtmlEmail email = new HtmlEmail(); email.setHostName(mailhost); email.setSmtpPort(mailport); email.setFrom(args.from); email.addTo(args.receiver); email.setSubject(args.subject); email.setHtmlMsg(args

I'm trying to read the emails in a folder of an email account Office365 using JavaMail 1.4 api. My code is: public static void main(String argv[]) throws Exception { // Get a Properties object Properties props = System.getProperties(); // Get a Session object Session session = Session.getInstance(props, null); // Get a Store object Store store = null; Folder rf = null; if (CUR_MAIL_PROTOCOL != null) store = session.getStore("imap"); // Connect if (CUR_MAIL_HOST != null || CUR_MAIL_LOGIN != null || CUR_MAIL_PWD != null) store.connect("outlook.office365.com", 993, "**MYEMAIL**", "**MYPASS**");
