Hi,

Welcome to JavaRanch!

I'm moving this to our "Java in General (Beginner)" forum where it will get the attention it deserves.

Basically you have too many closing )'s

You have

Product newProd = new Product(Integer.parseInt(txtCost.getText()), txtName.getText()), txtbrief.getText());

It should look like this:

Product newProd = new Product(Integer.parseInt(txtCost.getText()), txtName.getText(),txtbrief.getText());

There is a need for the extra ) after txtCost because you are closing out the parseInt() method, and there is a need for the extra ) after textbrief because you are closing out the constructor, but there is no need for the extra ) after txtName.

Hope that helps.

Teaching yourself anything is always the cheapest way, but it definitely takes a lot of time and effort.<br /> <br />Thank you javaranch <a href="http://"http://faq.javaranch.com/view?HowToAskQuestionsOnJavaRanch"" target="_blank" rel="nofollow">Learn How to Ask Your Question</a> and be nice
