## Interface Thread.UncaughtExceptionHandler

- All Known Implementing Classes:
    ThreadGroup
  Enclosing class:
    Thread
  Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

      @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.

  Since:
    1.5
