Java default constructor
<p>i'm very new to java and i'm having difficulty figuring out what exactly a default constructor is - can you tell me which one of the following is a default constructor and what differentiates it from any other constructor?  thanks, antanis</p>

<pre><code>public Module()
    {
       this.name = "";
       this.credits = 0;
       this.hours = 0;
    }

public Module(String name, int credits, int hours)
    {
      this.name= name;
      this.credits= credits;
      this.hours= hours;
    }
</code></pre>
