The uncaught exceptions are the exceptions that are not caught by the compiler but automatically caught and handled by the Java built-in exception handler. when an exception happens, propagation is a process in which the exception is being dropped from to the top to the bottom of the stack and in to the calling chain to be cut and If not caught there, the exception again drops down to the previous method, and so on until it gets caught or until it reach the very bottom of the call stack.This is called exception propagation.

The Java platform defines the many descendants of the Exception class. An exception occurs when an unexpected event happens that requires special processing.Exception handling attempts to gracefully handle these situations so that a program (or worse, an entire system) does not crash.
