Error Handling with Java

In order to enable developers to programmatically handle errors, when a error occurs the GrabzIt Java API throws a GrabzItException which contains a error code that directly maps to a error. How each error code maps to an error is indicated in the below table, this avoids the need to parse error messages.

An example of a GrabzItException exception using error codes to determine how to handle a error is shown below.

try
{
    GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret");
    grabzIt.URLToImage("http://www.google.com");
    grabzIt.SaveTo("images/result.jpg");
}
catch(GrabzItException e)
{
    if (e.getCode() == ErrorCode.PARAMETERNOURL)
    {
        //Please enter a URL
    }
}
