How to use the java api to retreive all values in one item

I'm using java and I need to obtain 1. a list of all values stored in a specific item and 2. any single value stored in a specific value. I don't want a search, just the equivalent to SELECT qualifiers1 from table.

I found a couple of close answers but they were 2 years old and one had an outdated link. The only examples I can find are those that are searching for specific values.
the design of the documents I'm retrieving looks something like this:
"id": "1234",
"householdId": 5678,
"1": "4ed6e659",
"8": "208440404",
"9": "22",

What I want to retrieve is a list of the values from qualifiers.1.
