[GitHub] [arrow] davisusanibar opened a new issue, #37728: [Java]: Using an Iterator/Iterable/Stream to provide objects to a Java Collection for testing assertions

davisusanibar opened a new issue, #37728:
URL: https://github.com/apache/arrow/issues/37728

   ### Describe the enhancement requested
   
   Use an Iterator/Iterable/Stream to provide objects into a Java Collection and use it for standard assertions.
   
   Improve this method of comparing values of Vector Value objects, for example:
   
   ```
           assertTrue(reader.getVectorSchemaRoot().getVector("id").toString().equals("[19, 1, 11]"));
           assertTrue(reader.getVectorSchemaRoot().getVector("name").toString()
               .equals("[value_19, value_1, value_11]"));
   ```
   
   ### Component(s)
   
   Java

   So to clarify, the idea is that we could build some wrapper/adapter over a Vector (or VectorSchemaRoot) to support iteration over it as Java objects, as a more convenient (if less performant) version of the Reader classes. Then you could easily turn that into a testing API.
