스레드 오류 잡기 연습

All exceptions that occur while the Solution thread is running must be handled by one of these options: 1. If it's an Error, then display "Can't keep running". 2. If it's an Exception, then display "Needs handling". 3. If it's a Throwable, then display "Wait and see". Implement this logic.

Create your own UncaughtExceptionHandler as a local class inside the constructor. The UncaughtExceptionHandler should hide the thread name with asterisks and display a description of the error that occurred. "Thread-0" must be replaced with "********". "Thread-4321" must be replaced with "*********

Implement the UncaughtExceptionHandler interface in the Solution class, which must: 1. Interrupt the thread that threw the exception. 2. Display the exception's stack trace, starting with the innermost exception.
