JavaCC

Javacc is a language that helps computers understand other languages. It's kind of like a translator for computer programs. Imagine you're talking to someone who only speaks Spanish, but you only know English. You might need a translator to help you understand each other. That's what Javacc does for computers.

Javacc works by taking a set of rules (called a grammar) that describe how a particular language works. This could be a programming language like Java or a special language for a specific application.

Once Javacc has the grammar, it can read in sentences in that language and translate them into something the computer can understand. It can also check if the sentences are written correctly or not.

So, in short, Javacc is like a translator for computers that reads in a set of rules and helps the computer understand different languages.
