Lesson 4: Java Loops and Iterations | Learn Java Programming from Scratch

Welcome to Lesson 4 of the CodeStart: Java Programming from Scratch series! 💻
In this lesson, we’ll dive into Loops and Iterations — one of the most powerful concepts in programming that helps you repeat actions efficiently.

💡 What You’ll Learn

✅ What loops are and why they’re essential in programming
✅ The three main types of loops in Java:

for loop – repeats actions with a clear counter

while loop – repeats while a condition is true

do-while loop – runs first, then checks the condition
✅ How to use break and continue to control your loop flow
✅ Real-world coding examples like counting numbers, displaying patterns, and processing data

🧠 Why This Lesson Matters

Loops allow you to automate repetitive tasks — making your code shorter, smarter, and more efficient.
They’re a key part of data processing, algorithms, and real-world program logic.

💻 Hands-On Practice

Follow along step-by-step and code each example with me.
Experiment with loop counters, conditions, and even nested loops to see how they work in different situations.
Remember: the best way to master loops is to practice and experiment!
