Sixty animated classes, sixteen lab sessions — every concept taught visually with live simulations, real computations and its own real-world example, from "why software needs organising" all the way to lambdas, streams and JavaBeans.

What the five units build, how every session teaches — visual simulations, one line per press, predict-then-run — what the exam actually asks, and the exact toolchain: JDK 21, Notepad++, then Eclipse. Twenty minutes, zero syntax, full map.
WATCH THE TRAILERTHE SPINE · STRICT 4 CLASSES PER LAB
Classes teach; labs make your hands prove it. After every fourth class a lab lands — Lab 0's warm-up first, Lab 15's integrated revision last. Chips light up as sessions are published.
Why OOP exists · classes & objects · Scanner, types, arrays, operators, control flow · methods, constructors, inheritance basics.
Singleton · abstract & nested classes · interfaces as contracts · packages · the full exception-handling machinery · threads, lifecycle & synchronization.
String / StringBuffer / StringBuilder mastery · wrappers, Object class & generics · files, byte & character streams · serialization.
List, Set, Map and friends · iterators · Comparable vs Comparator · the legacy classes exams still love.
Functional interfaces & lambda expressions · the Stream pipeline · regular expressions · JavaBeans, then the course close.
THE METHOD
Code never appears as a wall. Every program builds line by line — Teaching mode advances on the clicker; Learning mode gives you a Next-line button and a slider on every panel.
Every activity is written by hand before it's typed. Solutions stay behind an honesty gate until your attempt is in the notebook — and 52 real past-exam questions are solved point by point where their concept is taught.
Delivery partners for inheritance, ticket counters for threads, canteen cards for encapsulation — each session picks the real-world situation that makes its concept obvious, and animates it as a step-by-step visual simulation before any code appears.
