Focus: Method.invoke
Java: Method.invoke
Answer
Method.invoke() may throw several exceptions, handle them appropriately.
When using Method.invoke(), you must be prepared to handle a variety of exceptions, such as IllegalAccessException, InvocationTargetException, and NoSuchMethodException. InvocationTargetException wraps any exception thrown by the invoked method itself. For instance, if you were calling a 'processOrder' method that may throw a 'OrderProcessingException', it's crucial to catch and handle this within an e-commerce platform to maintain robustness.
