Learn

Every lesson explains the idea in plain English, shows a small Java example, walks through it line by line, and warns you about common mistakes.

Unit 1

Starting From Zero

0/5 done

You do not need any coding background. This unit explains what programming is, what Java is, how Java runs on your computer, and how to write and read your very first Java program.

Unit 2

Java Fundamentals

0/7 done

The building blocks. Before objects make sense, you need to store values, take input, make decisions, repeat work and organise code into methods.

Unit 3

Classes and Objects

0/5 done

Now the OOP journey begins. You will learn how to design your own types using classes, create objects from them, initialise them with constructors, and protect their data.

Unit 4

The Four Pillars in Depth

0/5 done

The classic OOP pillars. You will reuse code with inheritance, let one name behave differently with polymorphism, and hide complexity with abstract classes and interfaces.

Unit 5

Applying Java OOP

0/5 done

The finishing unit. These are the features you need to write complete, safe, well-organised Java programs — and then you build a small project with them.
