• Execepts. A condensed version of the text narrative, for reference while online.
• Lectures. Curated studio-produced online videos, suitable for remote instruction.
• Java code. Hundreds of easily downloadable Java programs and our I/O libraries for processing text, graphics, and sound.
• Data. Real-world data sets for testing code (ours and yours).
• Exercises. Selected exercises from the book and “web exercises” developed since its publication, along with solutions to selected exercises.
• Programming assignments. Creative programming assignments that we have used at Princeton.
