February 21, 2023 - At a very high level, basically you'll want at minimum these components: something that breaks up text into tokens, which are objects representing keywords, operators, etc.; something that reads those tokens and builds a parse tree, which is like a huge sentence diagram of the program you're compiling; and something that takes your parse tree and generates code from it. I know that's very vague and simplistic, but those are the most basic things a compiler has most of the time. So maybe start with a Token class, a Tokenizer class, a ParseTree class, a Parser class, and a CodeGenerator class? I wouldn't want to offer any more details than that, since I don't know Java very well, and I don't know anything about the language you want to compile.
