Handling loadStrings() from URL error

in Programming Questions • 1 year ago

I am using: loadStrings("http://www.processing.org/") right now for testing. When I try to load a URL that is invalid I get an error. How can I set up a conditional to test if it will fail and only perform loadStrings() if it doesn't fail without the error?

String[] lines = loadStrings("http://www.exxxample.com");
if (lines == null)
{
println("Failed");
}
else
{
println(lines[0]);
}

Alas, Processing dumps the error stacktrace on the console, which isn't nice...

Does that mean I'll get an error message even if I handle it that way? I may be performing that test more than once in a sketch, will the program run even though errors are being printed?

EDIT: If the answer is yes, then is it possible to load the source code of a website without using loadStrings()?

Fast answer (gotta go!): look at the source code of Processing to see how they do their loadStrings().
At least, you can manage the exception yourself!
