Definitions:

RuntimeException

A subclass of Exception in Java that represents exceptions that can occur during the runtime of a program and are not checked exceptions.

Explicitly Caught

To be explicitly caught refers to explicitly handling exceptions using try-catch blocks in programming, as opposed to allowing exceptions to be handled by default handlers.

Try-Catch-Throw Trio

This refers to the combination of using try and catch blocks along with a throw statement in exception handling, allowing for errors to be caught and possibly re-thrown for further handling.

Handling Exceptions

Handling exceptions involves writing code that responds to errors during program execution in a controlled manner, thereby preventing the program from crashing unexpectedly.
