>             Project: Apache Arrow
>          Issue Type: Improvement

> This should apply primarly to DataType, Field, and Schema. It should not try to print things like metadata and nullability. This is not meant for serialization but quick glance.

> {code:java}
> i32
> list<i32>
> dict<utf8,i8>
> struct<<a,i32>,<b,struct<<n,utf8>>>>
> schema<<a,i32>>{code}
> Once we have that, we can have a small print diagnostic to array/tables like R.
