   This stream processing logic can be simplified. The intermediate collection 
to a list, getting a spliterator, and then creating a new stream via 
`StreamSupport.stream` is unnecessary and less efficient than chaining the 
stream operations directly. This simplification can be applied to the logic for 
`bElements` and `cElements` as well.
   
   ```java
               elements.stream()
                   .filter(
                       Predicates.compose(new StartsWith("a"), new 
ExtractWriteDestination()))
                   .map(Functions.toStringFunction())
                   .collect(Collectors.toList()),
   ```
