Core Java by Cay Horstmann (https://horstmann.com/corejava/ https://horstmann.com/corejava/) is a well-structured and concise review of major features.

So completely skipping the "Fundamentals" volume was ill-advised while the "Advanced Features" volume had some boring and mostly unnecessary chapters.
