This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
The first one refers to a String object which is created when the class is loaded. The second one creates a copy of an existing String object. The second one is a form you'll never see except on certification exams, or in code written by newbies who have learned Java by studying for those exams!
