Additional Notes
How does MethodHandles differ from traditional reflection?
Track: Java
Topic: Reflection API
Focus: MethodHandles
Java: MethodHandles
Answer
MethodHandles are more efficient and type-safe.
While both MethodHandles and reflection allow for dynamic invocation, MethodHandles are designed to be more efficient and type-safe. Whereas reflection incurs a performance penalty due to its generic nature, MethodHandles benefit from JVM optimizations. For instance, MethodHandles can be used to access a method directly without the overhead associated with reflection's Method.invoke().
