Fill2.java demonstrates the use of which java feature to simplify code?

  1. Generics

  2. Varargs

  3. Reflection

  4. Dynamic Proxies

The correct answer is: Varargs

Varargs (variable arguments) are a feature introduced in Java 5 to reduce the amount of code needed when accepting a variable number of arguments in a method. The other options, while useful, do not directly relate to simplifying code in the same way that varargs do. Generics are used to define and enforce the type of data being stored in a collection, while Reflection is used to examine and modify the behavior of classes at runtime. Dynamic Proxies are used to create objects that implement interfaces at runtime based on custom behaviors. None of these features directly simplify code in the same way that varargs do.
