Can someone explain to me what the difference between a setter and constructor is? and If this code looks right? public class Square {
// private instance veriable
private double length;

// constructor
public Square(double l)
{
length = l;
}

// setter
public void setLength(double length)
{
this.length = length;
}

A constructor has the same name as the class and builds things as soon as the class is turned into an object.  A setter allows access to the private internals of an object.  I saw a great example recently, let me see if I can find/remember where.  I think I know, and if I am right, it will show how they are different, but a constructor can use a setter!

This is an example with Java, but it shows how overloaded constructors work. The constrictors are linked to a setter. The rules are similar no matter what the language. The specifics of how to build a constructor are all that really change. Do you use __SELF__ and so on.... http://thenewboston.org/watch.php?cat=31&number=39
