Methods In List class | Premium Salesforce Development Tutorial 2025

In this amazing video on “Methods In List class”, we will explore various methods available in the List class in Apex programming. While a list is a collection, it is represented as a class in Apex, requiring specific methods for manipulation. We cover the most commonly used methods that allow you to efficiently work with lists. First, we'll start by discussing the "size" method, which returns the number of elements stored in a list without the need for a loop. Then we will proceed to the "get" method, which allows you to retrieve a value at a specific index within the list. After this, we will understand about the "remove" method, which allows you to delete an element from a list using its index. We illustrate how list indices are automatically adjusted after removal. Continuing the discussion, we will then explore the "clone" method, which creates a copy of a list and assigns it to a new variable. We then look at the "set" method, which enables you to replace a value at a specific index with a new value. After this comes one of the most essential methods, "sort,". We demonstrate how this method arranges the elements in ascending order within the list. Following that, we highlight the commonly used "isEmpty" method, which returns a boolean value indicating whether a list is empty or not. Finally, we'll take a look at the "clear" method, which removes all elements from a list, leaving it empty. We conclude by emphasizing the significance of these methods in working with lists in Apex programming. Questions Covered in the Video: How do I determine the size of a list in Apex?
