No..class cannot be Synchronized. We can have synchronized blocks or methods.

Your query is prone to ambiguous interpretation . What exactly do you mean by 'class synchronization'?

If you mean synchronizing on the class object of some class,then yes.

As for the need,well it could be for preventing race conditions arising out of multiple threads concurrently trying to access the static variables of a class.

[Rohith Kumar Singh]

By saying 'if a class can be synchronized...' if you meant if a class member i.e., a static member can be synchronized then the answer is Yes. You just need to acquire lock on the Class object of the associated Java class.
Cheers,
Rohit

The question "can class be synchronized" does not make sense. A block of code can synchronize on the class.. for example: synchronize(MyClass.class) so that the code associated with all instances of that class cannot be re-entrant in that block. You can also synchronize on a single instance such as synchronize(this) or synchronize(xyz) where xyz is an instance. Make sense?
