问题 I am launching my Scala SWT application using: java -splash:splash.jpg -jar application.jar Using JDK 1.6.0 on Mac OS X 10.9.1 the splash screen was opened immediately (seconds before the actual application window opened). I used the following code to close the splash screen when the SWT application window opened: // When the window opens for the first time close the splash screen if exists val splash = SplashScreen.getSplashScreen if (splash != null) { shell.addShellListener(new ShellAdapter

问题 This issue only seems to occur since I upgraded from 1.5 to 1.6 The main JFrame, randomly seems to get stuck infront of every other application in windows. Even another JDialog popping up set to alwaysontop(true) will be behind this main JFrame. Any ideas on what could be causing this issue? / Any ideas for solutions? Never had this issue before on Java 5. 回答1: Sorry guys it seems it was a program used as a screen splicer that was causing an issue with th Java program. Once the screen splicer

问题 Using dom4j DOMDocument to feed validator.validate(DOMSource) fails in java 1.6 (with xsi:noNamespaceSchemaLocation is not allowed to appear in root element), works in 1.5 I'm finding the following problem quite intractable (OK, that's an understatement) - any insights will be appreciated. Currently it seems like the best idea is to drop dom4j in favour of e.g. XOM (http://stackoverflow.com/questions/831865/what-java-xml-library-do-you-recommend-to-replace-dom4j). I've been validating in

问题 A coworker and I had a discussion about how Java represents enumerations. I was under the impression they were strictly ints like C/C++. Or, if you add behavior (Type-Safe enum), it gets wrapped in a class. He believed that if it's small enough Java would compact it to a byte. However, I found this on the Oracle site: Java programming language enums are far more powerful than their counterparts in other languages, which are little more than glorified integers. The new enum declaration defines

问题 Just noted that you can´t sign Android APKs with the Java 1.7 jarsigner. So I wonder why this is and what is the difference between the 1.6 and 1.7 signer? 回答1: This is because the default digest algorithm for Java 1.7 is SHA-256 while for Java 1.6 it's SHA1withDSA . Java 1.6 Jarsigner docs Java 1.7 Jarsigner docs 回答2: Yes you CAN use 1.7! It is very tricky to find info on the usage with 1.7, but once found it is reasonable simple: For keytool include -sigalg SHA1withDSA -keyalg DSA -keysize

问题 Is it possible to get a Path object from a java.io.File ? I know you can convert a path to a file using toFile() method, but I couldn't find the opposite conversion. Is there a way to do this in Java 6 or lower? 回答1: Yes, you can get it from the File object by using File.toPath(). Keep in mind that this is only for Java 7+. Java versions 6 and below do not have it. 回答2: From the documentation: Paths associated with the default provider are generally interoperable with the java.io.File class.

问题 I have an xml string which I get via a REST call. However, some of the attributes have corrupted values. For example: <property name="foo" value="Some corrupted String because of "something" like that"/> How can I replace double-quotes either not preceded by value= or not follown by /> with a single quote and get a valid XML string out of that corrupted one in Java 6? EDIT: I have tried to modify this lookahead/lookbehind regex that was used for VisualBasic. But because of the incompatibility
