Reflection Impact on Type Safety?
Track: Java
Topic: Reflection API
Focus: Method.invoke
Java: Method.invoke
Answer
Reflection bypasses compile-time type checking.
Using reflection, you can invoke methods without knowing their types at compile time, which bypasses Java's type safety checks. This can lead to runtime errors if the method signatures or types do not match. For example, if you mistakenly invoke 'addItem(String)' instead of 'addItem(Integer)' on a shopping cart object, you might encounter a ClassCastException during execution.
