Thanks, but I was trying to use a predefined function in util or array class and it would give me as I mentioned " cannot resolve symbol" . I wanted to know if the method exists or is it deprecated. Which classes should I import or should I make it work?
Two things: 1). Remember, any method call without an object becomes a method call to this. So your call to "arrayToString" is looking for that function in the current class. 2). I don't know of any standard Java class that will do what you are asking to do here. A quick search on Google shows that many people have written this method, but I don't see that this is part of SUN's API.
