How can I use the “list” keyword in Apex for storing and processing w collection of records with the “pending” status?

 In the context of Salesforce, the “list” keyword is commonly used for storing the collection of records of data. Here is how you can effectively use the “list” keyword for storing and processing a collection of records with the “pending” status:-

Public class CustomObjectProcessor {
    // Method to process bulk updates for custom objects with ‘Pending’ status
    Public static void processPendingRecords() {
        // Define a list to store custom object records with ‘Pending’ status
        List pendingRecords = new List();
        // Query for custom object records with ‘Pending’ status
        pendingRecords = [SELECT Id, Name, Status__c FROM CustomObject__c WHERE Status__c = ‘Pending’];
        // Check if there are any ‘Pending’ records to process
        If (!pendingRecords.isEmpty()) {
            // Iterate through each record for further processing
            For (CustomObject__c record : pendingRecords) {
                // Perform the required processing on each record
                // For example, update the ‘Status__c’ field to ‘Processed’
                Record.Status__c = ‘Processed’;
            }
            // Update the processed records using DML (Data Manipulation Language)
            Try {
                Update pendingRecords;
                System.debug(‘Pending records processed successfully’);
            } catch (Exception e) {
                System.debug(‘Error processing pending records: ‘ + e.getMessage());
            }
        } else {
            System.debug(‘No pending records found’);
        }
    }
    // Example usage in a test method or elsewhere
    Public static void main(String[] args) {
        // Call the processPendingRecords method to process pending records
        processPendingRecords();
    }
}
Here is the example given in java programming language:-
Import java.util.ArrayList;
Import java.util.List;
Public class CustomObjectProcessor {
    // Define a custom object class representing records
    Static class CustomObject {
        String id;
        String name;
        String status;
        CustomObject(String id, String name, String status) {
            This.id = id;
            This.name = name;
            This.status = status;
        }
    }
    // Method to process pending records
    Public static void processPendingRecords() {
        // Create a list to store custom object records
        List records = new ArrayList<>();
        // Simulate adding custom object records with ‘Pending’ status
        Records.add(new CustomObject(“001”, “Record1”, “Pending”));
        Records.add(new CustomObject(“002”, “Record2”, “Pending”));
        Records.add(new CustomObject(“003”, “Record3”, “Processed”)); // Simulating a processed record
        // Iterate through the list and process pending records
        For (CustomObject record : records) {
            If (record.status.equals(“Pending”)) {
                // Perform processing on pending records
                Record.status = “Processed”;
                System.out.println(“Record ID: “ + record.id + “ processed successfully.”);
            }
        }
    }
    Public static void main(String[] args) {
        // Call the method to process pending records
        processPendingRecords();
    }
}
