How can I write a code by using the “isEmpty” keyword in apex to check if the “caseList” is empty?

 In the context of Salesforce, here is the apex snippet given by using the “isEmpty” keyword to check if the “case list” is empty and displaying a message accordingly:-

Public class ShipmentProcessor {
    Public static void processShipments(List shipmentList) {
        If (shipmentList.isEmpty()) {
            System.debug(‘No shipments to process.’);
        } else {
            For (Shipment shipment : shipmentList) {
                If (shipment.Status__c == ‘Pending’) {
                    // Update status to “In Transit”
                    Shipment.Status__c = ‘In Transit’;
                    // You may need to perform DML operations to update the record in the database
                    // Example: update shipmentList;
                } else if (shipment.Status__c == ‘Delivered’) {
                    System.debug(‘Shipment with ID ‘ + shipment.Id + ‘ has already been delivered.’);
                }
            }
        }
    }
}

By using the “isEmpty” method, you can efficiently checking bid a list is empty before performing further operations, avoiding unnecessary processing on an empty list.
