From 16:00 UTC on January 17, 2026, to 20:00 UTC on January 17, 2026, we will perform planned maintenance on the Trailhead, myTrailhead, and Trailblazer Community sites. During the maintenance, these sites will be unavailable, and users won't be able to access them. Please plan your activities around this required maintenance.

Get Hands-On with an Iterable Variable in For Loops

Learning Objectives

After completing this unit, you’ll be able to:

  • Use an iterable variable in a for loop.
  • Implement an Iterable Interface in Apex.

Iterate Within For Loops More Easily with Iterable Variable

You can now easily iterate through lists or sets using an Iterable variable in a for loop. Instead of writing complex loops, developers can use this feature to simplify working with for loops that repeat a block of code in each item in a collection. Standardize how you loop through lists and sets to make your code more consistent.

Implement and Test an Iterable Interface in Apex

In this hands-on challenge, you create a custom Apex class that implements the Iterable. You then use this class to iterate over a collection of items within a for loop. This exercise explains how to simplify iteration in Apex using the Iterable interface.

It’s time to complete the hands-on challenge to maintain your Platform Developer certification.
