JavaViz
Java Visualizer and Trainer
$19.99 · Designed for iPad. Not verified for macOS.
The fastest way to prep for AP CS A—visually: live stack, heap, recursions, and FRQs stepped line by line. Learn by watching Java run, not guessing.
JavaViz is a Java visualizer and trainer: you step through real Java examples and see the stack, heap, control flow, recursion, and collections update as the lesson runs.
WHO IT IS FOR
• High school students preparing for AP Computer Science A—including newcomers who learn best by seeing what code does.
• Anyone in a first Java course, a bootcamp, or self-study who wants intuition for references, objects, arrays, ArrayList, and common algorithms.
WHAT YOU GET
• A structured curriculum from variables and control flow through objects, arrays, inheritance, recursion, libraries, and algorithmic thinking.
• Memory diagrams that show locals on the stack and objects on the heap as you move line by line.
• Optional panels when lessons need them: control flow, recursion, class hierarchy, parameter passing, and array traces for search/sort patterns.
• AP-style free-response (FRQ) entries with on-screen problem context, a solution walkthrough, space for your own attempt (saved on this device), and an implementation workspace that steps reference code.
• Section checkpoints and lesson reviews to reinforce ideas (points are for motivation; they are not an official AP score).
PRIVACY & ACCOUNTS
• You can use the lessons without an account. An optional account saves progress in this browser on the web build; treat the mobile app the same way unless you document cloud sync separately.
JavaViz focuses on clarity and practice—not on replacing the College Board exam, your teacher, or the official Java Language Specification.
