@FunctionalInterface public static interface Thread.UncaughtExceptionHandler
Interface for handlers invoked when a Thread
abruptly terminates due to an uncaught exception.
When a thread is about to terminate due to an uncaught exception the Java Virtual Machine will query the thread for its UncaughtExceptionHandler
using Thread.getUncaughtExceptionHandler()
and will invoke the handler's uncaughtException
method, passing the thread and the exception as arguments. If a thread has not had its UncaughtExceptionHandler
explicitly set, then its ThreadGroup
object acts as its UncaughtExceptionHandler
. If the ThreadGroup
object has no special requirements for dealing with the exception, it can forward the invocation to the default uncaught exception handler.
