How can I use the Apex utility to refractor the trigger considering the optimization of a trigger in an organization?

In the context of Salesforce, the apex utility classes in Salesforce can be used for encapsulating reusable logic and functionality which can be shared across multiple Components such as triggers, controllers, and even the process-related to batch. These utility classes can help improve code organization, maintainability, and even efficiency by centralizing common tasks and reducing code duplication.

Here is an example given of how you can execute a simple apex utility class and refractor a trigger for using it::

// Apex Utility Class
Public class TriggerUtility {
    Public static void processOpportunity(Opportunity opp) {
        // Common logic to process opportunity records
        // Example: Calculate total amount
        Opp.Total_Amount__c = opp.Amount * opp.Quantity;
    }
}
// Trigger
Trigger OpportunityTrigger on Opportunity (before insert, before update) {
    If (Trigger.isBefore) {
        If (Trigger.isInsert || Trigger.isUpdate) {
            For (Opportunity opp : Trigger.new) {
                // Call utility method to process opportunity
                TriggerUtility.processOpportunity(opp);
            }
        }
    }
}
