一、捕获线程中的异常

public class CatchThreadException extends ThreadGroup {private CatchThreadException() {super("ApplicationLoader");}// We overload this method from our parent// ThreadGroup , which will make sure that it// gets called when it needs to be. This is// where the magic occurs.public void uncaughtException(Thread thread, Throwable exception) {// Handle the error/exception.// Typical operations might be displaying a// useful dialog, writing to an event log, etc.System.out.println("CatchThreadException[ThreadGroup] uncaughtException execute");System.out.println("Catch " + thread + " exception: " + exception.getMessage());}public static void main(String[] args) {Runnable appStarter = new Runnable() {public void run() {// invoke your applicationSystem.out.println("appStarter run..");if (true) {throw new RuntimeException("test appStarter throw runtimeException");}}};new Thread(new CatchThreadException(), appStarter).start();}}

二、注意不要捕获error的异常

error 和exception区别

他们都继承自Throwable

对Error的子集的快速了解可以让你知道许多类的名字，如VirtualMachineError、ThreadDeath和LinkageError。在你打算截获这些错误时，确信你要处理它们，因为它们是严重的问题，所以是错误。

Error是Throwable的一个子集，它指的是一个合理的应用程序不能截获的严重的问题。大多数都是反常的情况。
