AP Computer Science A: Iteration and Loops

Imagine writing a program that needs to perform a single action hundreds of times automatically, like counting steps or a game with repeating tasks. How can programmers make a computer complete these actions efficiently?

In this WebQuest, you will explore iteration in Java and learn how to implement it in your real-world programming.

You will work in a group of 3-4 to create a narrated presentation (Canva, PowerPoint, or Google Slides) that explains to and teaches others about loops in Java.

Your project must include explanations, real-world applications, and examples of:

• "for" loops
• "while" loops
• "do-while" loops
• Enhanced "for" loops

Alongside a short demo program using at least one of each loop type.

1. Explore each of the following websites to learn the basics of loops in Java:
   • https://www.w3schools.com/java/java_for_loop.asp
   • https://www.w3schools.com/java/java_while_loop.asp
   • https://www.geeksforgeeks.org/java/loops-in-java/
2. Build presentation alongside code examples
3. Record narration, and practice for presentation
4. Submit!
