How can the issue with Arrays.asList() and types be resolved?

  1. By specifying the type explicitly with a comment

  2. By using Collections.addAll()

  3. By using type inference

  4. By using an explicit type argument specification

The correct answer is: By using an explicit type argument specification

Explicit type argument specification removes any ambiguity in the type of the list elements. Depending on the context, both A and B could potentially work, but they do not guarantee the correct type of the list elements. Additionally, Collections.addAll() may result in runtime exceptions if the type of the list elements is not compatible. Type inference, while useful in many situations, may not always work with Arrays.asList(), especially when dealing with primitive types. Therefore, using an explicit type argument specification is the most reliable way to resolve the issue with Arrays.asList() and types.
