InvocationTargetException is a confusing error message that Java developers often encounter. The good news? It's not the real problem - it's just Java's way of saying "something went wrong inside a method I tried to run for you." Think of it like a delivery person telling you "I couldn't deliver your package because there was a problem at the destination." The InvocationTargetException is the delivery person's message, but the real issue is what happened at the destination (inside your actual method).

Ruby has a robust error handling mechanism called rescue. The way it works is the keyword rescue specifies an exception handler that will catch and handle any exceptions that are raised in the begin block, the code block preceding the rescue block that may cause an exception. Here’s how it looks: When an exception occurs in the begin code block, Ruby transfers control to the rescue block and executes the code within it.
