Additional Notes
Type Safety and Method.invoke()?
Track: Java
Topic: Reflection API
Focus: Method.invoke
Java: Method.invoke
Answer
Method.invoke() can cause runtime errors if types don't match.
When using Method.invoke(), you must ensure that argument types match the method's parameter types. These mismatches don't surface until runtime, leading to potential ClassCastExceptions. In a REST API handler, if a method expects a User object but receives a String, the application may crash or behave unexpectedly.
