Lesson: 01 | AccountUtility | GetAccountByID

User Story
Codes

User Story

As a Salesforce developer,
I want to create a program that accepts an Account ID as input and retrieves the corresponding Account record, returning the fields: Id, Name, Industry, and Phone,
So that I can access the details of an Account or return null if the Account is not found or the ID is invalid.

Acceptance Criteria:

The program accepts a valid Account ID as input.
It retrieves the Account record and returns the following fields: Id, Name, Industry, and Phone.
If no Account is found for the provided ID, the program returns null.
If the Account ID is invalid or null, the program returns null.

Codes

public static Account getAccountById(Id accountId) {
    if (accountId == null) {
        return null;
    }

    List<Account> accounts = [SELECT Id, Name, Industry, Phone FROM Account WHERE Id = :accountId LIMIT 1];

    return !accounts.isEmpty() ? accounts[0] : null;
}
