问题 This question already has an answer here : javafx 8 compatibility issues - FXML static fields (1 answer) Closed 2 years ago . I'm working on a program for Insurance purposes and there I've a textfield called Reference Key this reference key is generated randomly every time I View the panel the other Scenes and classes needs this Reference Key , so I've made it static so that all the classes can reach this Instance directly ! My problem is that when I set the text for the textfield I get an

问题 So I was interested in appending files to a zip archive and I came across a few users who asked this question before and another user gave this code snippet as a solution to that problem: public static void updateZip(File source, File[] files, String path){ try{ File tmpZip = File.createTempFile(source.getName(), null); tmpZip.delete(); if(!source.renameTo(tmpZip)){ throw new Exception("Could not make temp file (" + source.getName() + ")"); } byte[] buffer = new byte[4096]; ZipInputStream zin

问题 is there any way to turn off exception message showing during run-time in Delphi application? i think there must be a directive to turn off exception message but i cant remember it. 回答1: Most exception messages can be suppressed by handling the TApplication.OnException event. The application object only displays an exception message if there isn't a handler assigned to that event. You're welcome to call TApplication.ShowException in your handler for certain exceptions if you want. That event

问题 This is my attempt so far to trap all exceptions in Jython code. The most difficult thing, I find, is trapping exceptions when you override a method from a Java class: with the "vigil" decorator below (which also tests whether the EDT/Event Despatch Thread status is correct) you can find out the first line where the code is thrown... so you can identify the method itself. But not the line. Furthermore, tracing stack frames back through Python and Java stacks is completely beyond me. Obviously

问题 I have this demo, which I dont need a particular solution with a redrawn architecture, but just understanding why behaves like that and any thing I am missing for avoiding it. I am wondering why: Compiler allows the insertion of an element that its not the type of the list into the list The ClassCast exception is thrown when we try to get the element instead of when pushing it import Test.*; //Inner classes import java.util.List; import java.util.ArrayList; public class Test<E extends Object>

问题 In C#, it is considered bad practice to throw exceptions in the Dispose method of an IDisposable . By contrast, in java the close method of AutoCloseable allows any Exception whatsoever to be thrown and forces the caller to handle it somehow. But what is the caller reasonably expected to do if this happens? This suggests that the attempt to close the resource failed somehow. So does the user have to try to close the resource again before continuing, perhaps with some sort of exponential

问题 I have written following code which is resulting in concurrent modification exception. How can I prevent it ? The idea is to escape all values of the Map and reconstruct the object (dO) back with new param map. try { Map<String,String[]> paramMap = dO.getParameterMap(); Set<Map.Entry<String, String[]>> entries = paramMap.entrySet(); Iterator<Map.Entry<String, String[]>> it = entries.iterator(); while (it.hasNext()) { Map.Entry<String, String[]> entry = it.next(); String[] values = entry

问题 I have this snippet. public final class StackOverflow{ class MyException extends Throwable{ } private void a(){ try{ }catch(MyException | Exception e){ } } } exception StackOverflow.MyException is never thrown in body of corresponding try statement I know that Exception is extending Throwable as well and also is a checked exception also MyException is extending Throwable which mades also a checked exception! My question is why Exception is not required to be thrown in the try catch but
