public void setUncaughtExceptionHandler(Thread.UncaughtExceptionHandler ueh)

Overrides java.lang.Thread.setUncaughtExceptionHandler.

Doc from java.lang.Thread.setUncaughtExceptionHandler.

Set the handler invoked when this thread abruptly terminates due to an uncaught exception.

A thread can take full control of how it responds to uncaught exceptions by having its uncaught exception handler explicitly set. If no such handler is set then the thread's ThreadGroup object acts as its handler.
