I haven't programmed consistently for more than three years, although I was reasonably comfortable before the break and have completed a few small projects since then. In about three days, I'll need to start coding every day again. The work should mostly involve objects, files, and similar fundamentals rather than anything especially complex. I still remember core object-oriented concepts such as constructors, attributes, getters and setters, loops, functions, interfaces, and inheritance. What would be the most effective way to use these three days so I'm not starting completely cold?

On your first day back, enable the project’s formatter, linter, and automated checks if they’re available. A short syntax review won’t necessarily remind you of current idioms or conventions, and these tools can quickly point out awkward or outdated code. Treat the first few tasks as a hands-on refresher and expect to look things up regularly.
The quickest refresher is to start writing code instead of trying to reread everything. Build one or two small projects that resemble the work you’ll be doing, such as a program that reads and writes files and models a few related objects. When you get stuck, look up that specific issue and keep moving. The concepts usually come back much faster through use than through passive review.
Use the actual language and tools you’ll be working with. Spend a little time skimming the official documentation for syntax and common library features, then make a small practice program using objects, collections, and file I/O. Since you only have three days, focus on practical fluency rather than trying to relearn the entire ecosystem.
