How to properly catch RuntimeExceptions from Executors?

由 心不动则不痛 提交于 2019-11-27 09:44:54
问题 Say that I have the following code: ExecutorService executor = Executors.newSingleThreadExecutor(); executor.execute(myRunnable); Now, if myRunnable throws a RuntimeExcpetion , how can I catch it? One way would be to supply my own ThreadFactory implementation to newSingleThreadExecutor() and set custom uncaughtExceptionHandler s for the Thread s that come out of it. Another way would be to wrap myRunnable to a local (anonymous) Runnable that contains a try-catch -block. Maybe there are other

Proper use of RuntimeException? [duplicate]

问题 This question already has answers here : Closed 9 years ago . Possible Duplicate: In Java, when should I create a checked exception, and when should it be a runtime exception? When should I derive an exception from RuntimeException instead of Exception ? A RuntimeException does not have to be declared in a method's throws clause, which may be good since it doesn't have to specifically listed or bad because it is good practice to explicitly declare a method's exception. Thoughts? 回答1: From

问题 What I want to achieve: I have a custom ListView adapter. To each Listitem I want to add a popup menu, pretty similar to the ListView in the current Google Play application. This is what I tried: Most of my code comes from this Android sample samples\android-19\ui\ActionBarCompat-ListPopupMenu CustomFragmentPageAdapter.java : // create new fragment mCustomFragment = CustomFragment.newInstance(position); CustomFragment.java public class CustomFragment extends ListFragment implements View

Why runtime exception is unchecked exception?

由 。_饼干妹妹 提交于 2019-11-27 03:56:28
问题 Generally if any class extends Exception , it becomes checked exception. Runtime exception also extends Exception. Then how is it unchecked exception ? Is it like they have a custom check in compiler for this special case? EDIT : I have proper idea about checked v/s unchecked exception and their pros & cos etc. I don't except differences between them in answer. 回答1: It's explicitly in the specification, section 11.1.1: RuntimeException and all its subclasses are, collectively, the runtime

Can someone please help me understand what is going on and how can I fix this problem? android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application at android.view.ViewRoot.setView(ViewRoot.java:509) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:177) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:91) at android.app.Dialog.show(Dialog.java:241) Peter Knego I'm guessing - are you trying to create Dialog with an application context?

Checked vs Unchecked exception

由 孤者浪人 提交于 2019-11-27 01:53:09
I've studied that: With an unchecked exception, however, the compiler doesn't force client programmers either to catch the exception or declare it in a throws clause. In fact, client programmers may not even know that the exception could be thrown. eg, StringIndexOutOfBoundsException thrown by String's charAt() method. what its mean? according to that code there is no need to put try catch block in code, but i've seen compiler forces to put the code in try catch block. I'm very confused what they are exactly? Unchecked exceptions are those that extend RuntimeException class. Compiler will

Please explain RuntimeException in Java and where it should be used

由 蹲街弑〆低调 提交于 2019-11-27 00:24:52
问题 I am following this great discussion at SO, titled: The case against checked exceptions , but I am unable to follow where exactly RuntimeException should be used and how it is different from normal Exceptions and its subclasses. Googling gave me a complex answer, that is, it should be used to deal with programming logic errors and should be thrown when no Exception should normally occur, such as in the default block of switch-case construct. Can you please explain RuntimeException in greater
