If you’re typing code without knowing what it’s about and the code doesn’t do exactly what you want it to do, you’re just plain stuck.

In this book, I divide Java programming into manageable chunks. Each chunk is (more or less) a chapter. You can jump in anywhere you want — Chapter 5, Chapter 10, or wherever.

In general, my advice is as follows:

  • If you already know something, don’t bother reading about it.
  • If you’re ...
