double method calls

Posted: Mar 14, 2006 5:57 PM

Say (because it's the case) I want to search a string for a specific phrase. As of now, we'll call it "cube".

I can do this:

stringName.findInLine("cube");

Yes? Fine I hope.

ABut say I need to respond the same to cube, Cube, CubE and CUBE?

Can I:

stringName.findInLine.ignoreCase("cube");

eh?

if not, how can I do this? Maybe before I do the search I can do this:

stringName.toLowerCase;
stringname.findInLine("cube");

Which way is more correct, if either are correct? My syntax may be a bit off, but hopefully I got my point across.

You can't do this of course.
findInLine is a method.

toLowerCase is a method which returns the string in lower case. The original String is NOT changed.

1. You didn't call it as a method
2. Even If you would have, it woudln't work, because you don't do anything with the result.
3. findInLine does not exist in the String datatype. Use indexOf instead (read the API for a complete description.
)

As mentioned by matt,
you may use str.toLowerCase().indexOf("cube") to check whether the returned value is -1 or not.
