Help with a very simple method for a very simple beginner.

Hi Everybody

How would I write a method / line of code to test wether or not an instance variable referenced a String? I'm trying to write a method that returns true if the variable references a String but I'm getting nowhere fast.

Many Thanks

How did you assigned that instance variable? Is it an Object variable?
i am little bit doubt, can you show more info?

Hi

The instance variables will be set with a mutator method and not in the constructor so when new instances are first created, the instance variable is null. Just as I'm writing this I think I've sussed it. The method I need to write needs to return true if the instance variable references a string, false otherwise so, if the variable is null, it returns false. I'll try that first and post my results
