WHAT'S INSIDE

PART A — JAVA FOUNDATIONS
1. What Java Is & How It Runs (JVM, JRE, JDK, bytecode)
2. Setup & Your First Program (install, Eclipse, javac and java)
3. Anatomy of a Java Program (public static void main, explained word by word)
4. Variables & Data Types (all 8 primitives, casting)
5. Operators
6. Input & Output (Scanner, command-line arguments, printf)
7. Conditional Statements (if, else if, switch)
8. Loops (for, while, do-while, for-each, patterns)
9. Arrays (1D, 2D, Arrays utilities)
10. Strings (String pool, == vs equals, StringBuilder)

PART B — OBJECT ORIENTED JAVA
11. Methods & Overloading
12. Classes & Objects (stack vs heap, garbage collection)
13. Constructors & the this keyword
14. Encapsulation & Access Modifiers
15. Inheritance & super
16. Polymorphism & Abstraction (abstract classes vs interfaces)
17. static, final & initialisation blocks
18. Exception Handling (checked vs unchecked, custom exceptions)

PART C — GOING FURTHER
19. Collections, Generics & Files (ArrayList, HashMap, HashSet)
20. Three Mini Projects

THE THREE PROJECTS
- Student Report Card — classes, arrays, loops, formatted output
- Bank Account System — encapsulation, inheritance, custom exceptions
- Library Manager — ArrayList + HashMap, search, issue and return

PLUS 4 APPENDICES
A. Java cheat sheet — all the syntax on one spread
B. 16 common errors: compile-time and runtime, real cause and exact fix
C. 30 practice questions with answers
D. A 30-day study plan you can actually follow

WHY THESE NOTES ARE DIFFERENT

- Handwritten style — blue ink, red key terms, yellow highlights, on ruled
paper. Easy on the eye, nothing like a wall of textbook text.
- Verified code — 51 complete programs, all compiled and run on JDK 21.
The console output printed in the notes is the real output.
- Diagrams, not paragraphs — JVM flow, stack vs heap, the String pool,
inheritance types, the exception hierarchy, method anatomy.
- Remember / Tip / Warning boxes on the things beginners actually get wrong:
the Scanner nextLine bug, == on Strings, integer division, missing break.
- Q&A at the end of every chapter, written the way vivas and interviews ask.
- A blank "Date" box on every page so you can log the day you studied it.
