23. ava Loops Guide: When to Use For, While, and Do-While Loops?

Struggling to decide between for, while, and do-while loops in Java? You aren't alone. While all three repeat code, choosing the right one makes your software clearer, smarter, and more efficient.
In this video, we break down the three main players in Java iteration to help you pick the precise instrument for the job:
1. The For Loop ("The Counter") This is your go-to tool when you know the exact number of repetitions upfront, like printing numbers 1 to 100 or iterating through a list of 50 items. It bundles the start, stop, and increment conditions into one clean line.
2. The While Loop ("The Watcher") Perfect for when you don't know the specific count, like reading a file with an unknown number of lines or waiting for user input. It keeps running as long as a specific condition remains true.
3. The Do-While Loop ("The Outlier") This is a niche specialist. Unlike the standard while loop, the do-while loop runs your code first and checks the condition second, guaranteeing the code runs at least once.
📌 Quick Cheat Sheet:
• Know the count? Use a For Loop.
• Unknown length? Use a While Loop.
• Must run once? Use a Do-While Loop.
Remember, in programming, clarity is king—always choose the loop that makes your intent obvious to future readers.
