I have a question that sorts data from a car report of txt file.

The question is: How do I listed cars sorted by their MAKE (Ford, Chevy ..etc). They only need the MAKE to be sorted so they can be all FORD cars under each other, then Chevy, DODGE .. so on and so forth like this:

And this is what I have so far:

Here's my source code:

I have a Java question that deals with reading the txt file and pulling data from it.

It's a bunch of used cars stored in a txt report file. They have several different lots that they sell from. The lots are identified by the 5 digit zip code followed by a zip code extension at the beginning of each record. They would like a report that lists all cars sold from all lots. This is what I come up with:

They would like the report to list 30 cars per page, on the report. Each page is to have headings and a page number. Like this:

My question is how do I list 30 cars per page instead of all together (Each page 30 cars with headings and page #)?

Here's my source code:

I was able to serialize a custom JFrame into a database, and I would like to deserialize it.
Unfortunately, during the alleged deserialization I have an error that I cannot resolve.

The best way I can describe what I'd like to achieve is by referring to how the SQL function INNER JOIN works for displaying data from two tables, determined by a matching column name.

I'd like to achieve a similar function, though by using Python (preferably 3.x), and instead of tables with a matching column name, I'd like to combine the entirety of two dictionaries together, based on a matching {k: v} pair.

For example...
