问题 This question already has answers here : Rethrowing an Exception: Why does the method compile without a throws clause? (6 answers) Closed 3 years ago . I came across a weird scenario in java today while coding around. I have a try..catch block in my method which does not have any throws clause and I am able to throw the exception object caught in the catch block. It is an object of the Exception class, hence it is not an unchecked exception. Also, It is not printing the stacktrace if

问题 I could not understand how java.nio.file.Files.isSameFile method is different from java.nio.file.Path.equals method. Could anybody please tell how they are different? 回答1: They are very different. For instance: final Path p1 = Paths.get("/usr/src"); final Path p2 = Paths.get("/usr/../usr/src"); p1.equals(p2); // FALSE Files.isSameFile(p1, p2); // true final Path p1 = fs1.getPath("/usr/src"); final Path p2 = fs2.getPath("/usr/src"); p1.equals(p2); // FALSE A Path is equal to another Path if

问题 im trying to extract some files from a jar-file downloaded using java-webstart. below code was used to locate the jar and initiate the FileSystem 1 final ProtectionDomain domain = this.getClass().getProtectionDomain(); 2 final CodeSource source = domain.getCodeSource(); 3 final URL url = source.getLocation(); 4 final URI uri = url.toURI(); 5 Path jarPath = Paths.get(uri); 6 7 FileSystem fs = FileSystems.newFileSystem(jarPath, null); This works fine when the jar-file is on a local disc, but

问题 Does IBM's java 7 bundle Java FX 2? I have JDK Version 7 Release 1 for Linux (32 bit) and it doesn't seem to contain it. If it doesn't, can I still use it, and what do I need to do for that? Thanks 回答1: No, IBM Java 7 does not include JavaFX 2. The Oracle distributions of Java 7 and 8 are the only supported Java runtimes that include JavaFX that I am aware of at this time. JavaFX 2 is mostly closed source, so you can't really port it to any other runtimes. JavaFX 8 is completely open source,

问题 It seems like both Cobertura and Emma are outdated now. They don't cope with Java 7 byte code. Running instrumented tests with Cobertura results in verification errors java.lang.VerifyError: Expecting a stackmap frame at branch target 41 in method ..... A shame really because Cobertura really is cool and well-supported. For Java 6 byte code that is. But now I'm looking for a replacement. Preferably having both Maven and Jenkins support. Are there any people in here using a code coverage

问题 I see quite a few changed interfaces in JDK7, e.g., the addition of ResultSet.getObject(String, Class<T>) . I was greatly surprised by this incompatible change, especially because I've never seen it discussed. I suppose the incompatibility doesn't matter when I use a JAR file instead of trying to compile the project myself, right? What is the proper way to support both JDK6 and JDK7? Does simply implementing the new methods and never using them suffice? 回答1: It seems <T> T getObject(int
