Java Loops : for, while, do-while

Introduction to Loops in Java

Imagine writing a task 100 times manually. Sounds exhausting, right? Loops in Java are designed to help you automate repetitive actions with control. In this tutorial, we’ll walk through all types of Java loops, when to use them, and how to write and understand their outputs step-by-step.

Types of Loops in Java

Java offers three primary looping constructs:

• for loop
• while loop
• do-while loop

Let’s explore each with real-life examples and logic breakdowns.

Java for Loop

The for loop is best when you know how many times you want to repeat a block of code. It’s concise and powerful.

The for loop in the following example runs 5 times, printing a friendly message each time with the count.
