Loading strings

schotsl

Hello,

When I'm loading a list of string from a file and that file does not yet exit, I want my script to create the file how would I go about this. I know that if you load a file that doesn't exit it will return a null value but how would I detect if it returned a null?

It depends of what you use. Some links below. If you use loadString for example, you can check if the return value is null:

String[] s =loadStrings("try.txt");
if (s==null) {
  println("Nothing there");
}
