In the following code:

class Node
{
int iData; // data used as key value
double fData; // other data
node leftChild; // this node’s left child
node rightChild; // this node’s right child

}

I understand that Node is a class and when we want to refer to a variable we can use the format "type name " format where type is the name of the class and name is the name of the variable.

So,In the above code, node leftchild is used where leftchild is a variable of type node. Why the node is not written as "Node" as N is capital while defining the class name. Shouldn't it be "Node leftchild" or "Node rightchild". Please clarify and thanks in advance.

PS: the above code is an excerpt from a book.

Yes you are right.
Code Conventions for the Java Programming Language: 9. Naming Conventions
"Class names should be nouns, in mixed case with the first letter of each internal word capitalized. "
And if the same node is meant as the class itself, then more than ever.
p.s.: Burn the book :)

It probably should be a 'Node' type instead of 'node' (unless there's something going on, not shown in the code snippet). That's the trouble with a lot of those books nowadays: those authors are only in it for the money and those books are full of crappy code. Also the names 'iData' and 'fData' are lousy imho, better change them to 'key' and 'data' instead ...

kind regards,

Jos

Thanks a lot for your answer guys.

Any good Java book recommended for algorithms?
