I know py and dataframes are usually used for this purpose, but in Java what is the optimal way to do this?
Currently I am using List<String>, is there a better way?

Generally for me I find it relatively simple to make a parser. I use either buffered reader or scanner to read in each line, then use .split to separate values based on commas

Depends on the use case, though if you are used to using data frames you may want to look into using a HashMap as that is the data structure most similar to a dataframe

No, HashMaps are not at all similar to pandas dataframes
