Access specifiers for constructors
<p>Suppose that there is a class A, Consider the following constructors:</p>

<pre><code>public A()
{
}

private A()
{
}

protected A()
{
}
</code></pre>

<p>Can anybody say what is the difference among the above 3 constructors? Why we need put access specifiers to constructors?</p>

<p>Thanks in advance.</p>
