Message:

a "gotcha" I have seen with String initialisation

Posted by Jody Brown on October 31, 2001 at 7:57 AM

I think Matt has summed it up very nicely. One other thing that I have noticed once or twice in my Java development career is code along the lines of:-

String myString = "" + someArbitaryObject.getArbitaryValue();

If the method getArbitaryValue() returns a null, you will get a string object created with the value "null". This has caused me hours of fun trying to debug code like this in the past, so it's worth watching out for.
