I’m trying to find a specific record. So what’s better to do? Use a mysql statement to find the record or grab the whole table, put in a arraylist and iterate through it until I find what I want?

It is always better to offload database work to database.
Some of the advantages I see are:
You will get only the data you want, which improves performance, result will be faster (Most of database servers comes with optimization to improve query execution paths).
Save the space. You don’t need to keep unwanted data in runtime memory
