By default, ChatGPT generates stepwise code that requires too much time to fully comprehend. I wanted it to do better, so I supplied a prompt describing the kind of code I wanted:

YOU:

I will be asking you to write Java code. Write all code as Jeff Langr. Jeff Langr (Jeff) has a specific coding standard. Here are the rules for your standard for Java language programming, which I will refer to as Jeff-Java when appropriate.
