copied!<p>I believe there are <em>multiple</em> reasons for <strong>namespaces</strong>. One way I understand it is: <code>private</code>, <code>protected</code>, and <code>public</code> expressions help a lot in <em>team environments</em> so that other devs don't end up using <em>methods</em> you didn't intend them to. That being said, you only use <code>private</code> when methods or properties only need to be accessed by that same object. Use <code>protected</code> when you need an inheriting class to carry that same functionality and use <code>public</code> when an object of a different class needs to access your object.</p> <p>eg:</p> <p>Class <code>Victim</code> has</p> <ul> <li>private method haveAnxiety()</li> <li>public property appearsToBeRich:Boolean</li> </ul> <p>Class <code>Robber</code> has</p> <ul> <li>private method profile(obj:Victim)</li> <li>private method rob(obj:Victim)</li> </ul> <p><code>Robber->profile()</code> will need to access <code>Victim->appearsToBeRich</code>. If <code>Victim->appearsToBeRich</code> returns <code>true</code>, then that <code>Victim</code> object will get <em>robbed</em>. a <code>Robber</code> object never needs to run <code>Victim->haveAnxiety</code> as the <code>Victim</code> will run <code>this->haveAnxiety()</code> as soon as that <code>Victim</code> object starts getting robbed.</p> <p>Granted, real world examples are a <strong>LOT</strong> more complex than my example (and I hope they are much more <em>graceful</em>). Anyway, I hope that helps.</p>
