How can I throw an exception in a Java web project that can't be caught and which ends execution?

Question

If I have a function that does not throw an exception in its signature, but which reaches a condition that should stop all execution, is it possible to throw some kind of exception without altering its signature and that of all calling functions? I tried using response.sendError(500,"My Error"), but it occurs to me that that may not stop execution.

For example, I have coded often in PHP to exit + some small output, but I read that that stops the entire server in Java.

抛出RuntimeException或其子类。
