Added the "Getters and setters" section based on the lecture today. --Yugan 06:09, 23 July 2008 (UTC)

Getters and setters

Here's an alternative set of guidelines our group came up with:

• Always make fields have private access.
• Only write getters and setters as needed.
• External: access to fields using getters and setters.
• Internal: access to fields directly, but only if it's the same object. Use getter and setters if same class, but different objects.
• Getters should be read-only (i.e. Collections should be returned as unmodifiable Collections)
