[SOLVED] Cannot find symbol error?

Hi, I'm trying to create a priority queue based on the probabilities of chars as provided by a text file. However, on line 91 when I create a new node, it yields an error:

line 91: CharNode node = new CharNode();
cannot find symbol
symbol: constructor CharNode()
location: class CharNode

CharNode class:

class CharNode
{
// data members, all of which may need to be private
char c;
double prob;
CharNode left, right;

public CharNode(double p, CharNode l, CharNode r)
{
prob = p;
left = l;
right = r;
c = 0;
}

public CharNode(char c, double p)
{
this.c = c;
left = null;
right = null;
prob = p;
}

public CharNode getLeft()
{
return this.left;
}

public CharNode getRight()
{
return this.right;
}

public char getC()
{
return this.c;
}

public double getProb()
{
return this.prob;
}

}

Why is that (I'm sure it's some stupid mistake)? Thanks in advance!

This is not an obvious mistake.

Add a contructor to your CharNode
that has the following signature:

CharNode(){}

The compiler makes this request
because you have another constructor
in CharNode. Because of that
constructor's presence, you must
specify this other constructor.

It's a confusing rule to get used to,
but it does make sense after you
consider it about two dozen times.

You're calling a default constructor for CharNode, a constructor without parameters, and no constructor like this exists.

Thanks! Works great now!
