Java: MethodHandles
Answer
Access public members across classes. Frame the concept in practical terms so you can explain it during interview discussion.
MethodHandles.publicLookup() is used to create a Lookup object that can access public methods and fields across different classes. This is similar to reflection's ability to access public members but is generally more efficient. For example, you can use publicLookup() to access a public method of an unrelated class.
