help me with this
Can someone explain why the last rows (Row 20-22) are necessary? What would happen if we didn’t have it and we called upon the UserDTO class?

that's a getter, it basically allows read only access to a property, and allows you to do extra checks before handing out the value, for example
there's also setters that accept a value, which then set the backing field, after (again, for example) doing some checks on the passed value
name is private, which means that only UserDTO itself can access it. the getter basically provides read access, but since there's no setter, it can't be set from outside
