Java Loops Tutorial | Why Most Beginners Get Infinite Loops Wrong
Learn how to execute code repeatedly using loops in Java, one of the most important control flow concepts in programming.
In this tutorial, you’ll understand how to automate repetitive tasks using for loops, while loops, and do-while loops. You’ll also learn how to control loop execution using break and continue, along with common mistakes beginners make when working with iteration.
What You’ll Learn
Why loops are used in programming
How for loops work (counter-controlled iteration)
How while loops work (condition-controlled iteration)
How do-while loops differ (guaranteed execution)
Using break to exit loops early
Using continue to skip iterations
Common mistakes in loop conditions (infinite loops, off-by-one errors)

Common Pitfalls Covered
Infinite loops due to incorrect conditions
Off-by-one errors in for loops
Misuse of break and continue affecting logic flow
Practice Challenge
Try writing programs to:
Print numbers from 1 to 100 using a loop
Calculate the sum of first N natural numbers
Print only even numbers using continue
