This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
I think the difference is that, the first code defines a class lock. So, when you instantiate two objects of the same class, the second string must wait for the first to finish, since it is unable to access the class lock. In the second example, you have object locks. Since you have two different objects, nothing prevents the two threads fom running concurrently. Correct me if I'm wrong, Alex
Alex is right u cannot execute non-static synchronized methods simultaneouly for the same object whereas for the static sync methods since they are assoiciated with the class they cannot be executed for the class simultaneoulsy

For a static method, a " lock " is obtained for the class before the execution of the method. Correct me if I'm wrong.
