Type mismatch error. Posted: Jun 17, 2006 2:06 AM

I have two classes a Product class and a Product Group class. In the product class a create an accessor method.

private productPrice
public void setProductPrice(double productPrice) {
		this.productPrice = productPrice;
	}


In the productGroup class (I am getting data from a db) I do the following:

Product currentProduct;
while (rs.next()) {
  currentProduct = new Product();
  double productPrice = currentProduct.setProductPrice(rs.getDouble("productPrice"));
    //Add the Product Object to a List
}
 


the javac compiler is throwing the following error: ProductGroup.java:65: setProductPrice(java.lang.String) in Components.Product ca
nnot be applied to (double)
currentProduct.setProductPrice(rs.getDouble("pro
ductPrice"));

I don't understand why it is saying that setProductPrice takes a java.lang. String type when I am coding it to take a variable of type double. Thanks for any answers.

setProductPrice returns void, so you can’t assign it to productPrice.

If that’s the only thing that’s wrong, it’s a very misleading error message.
