This is me working through Liang’s “Introduction to Java Programming and Data Structures” from front to back, one chapter at a time. It isn’t a tutorial and it isn’t a tidy course recap. It’s just my raw notes: what actually clicked, the exercises I slogged through, and the honest bits about where I got stuck. The plan is to get through all 29 chapters before the summer runs out.
The grid below tracks where I am chapter by chapter, and the devlog underneath captures what I picked up as I went. Both update by themselves whenever I push progress to the repo.
