Trailhead Challenge | Oriented programming for admins | Use sObjects and DML

Acme Inc. has opened three new locations in Texas. Acme needs to insert the new accounts into its database. Create a class and one method that creates three new accounts and adds them to the database.

• Create a public Apex class named AccountHandler
• Add a public static method to the class:
  • Name: insertAccount
• Include a parameter for the number of new accounts:
  • Data type: integer
• Create a list of Account records:
  • List name: addAccounts
• Use a while loop to add three new Accounts to the list, where n is a value that is incremented by 1 during each iteration of the loop:
  • Name: Acme Inc n
  • AccountNumber: A000n
• Hint: You did something like this when you created three new Tea Factory stores.
• Write one DML statement that inserts all three records into the database at one time
• Run your insertAccount method.

public class AccountHandler {
    public static void insertAccount(Integer numAccts) {
        List<Account> addAccounts = new List<Account>();
        Integer counter = 1;
        while(counter <= 3) {
            Account a = new Account();
            a.Name = 'Acme Inc ' + counter;
            a.AccountNumber = 'A000' + counter;
            addAccounts.add(a);
            counter++;
        }
            if(addAccounts.size() > 0) {
            Database.insert(addAccounts);
        }
    }
}
