Author	Topic: constructor problem
Mike unregistered	posted February 21, 2000 05:12 AM Just looking at Robert&Heller Cert Study Guide and found the following:- Is it true you can have 1) final constuctor 2) abstract constuctor 3) native constructor 4) synchronized constructor I dont understand why any of the above can be true.
Jim Yingst sheriff	posted February 21, 2000 12:29 PM Roberts/Heller/Ernest are wrong again - none of these are legal. I assume you're looking at page 91? The column labeled "Method/Constructor" should really just be labeled "Method" - then it would be OK. As it is, it's amazingly wrong. Static is another modifier they say is legal for a constructor - it isn't. This is verified in the JLS here.
