Answer
They offer a faster, more flexible way to invoke methods.
MethodHandles provide an alternative to reflection for method invocation, offering better performance and flexibility. Unlike reflection, which is more static, method handles can adapt to different method signatures dynamically, making them suitable for high-performance scenarios. For example, in a performance-critical application, method handles can replace reflection to invoke methods annotated with RetentionPolicy.RUNTIME for improved efficiency.
