Can constructors be synchronized in Java?



Can constructors be synchronized in Java?
No, constructors can not be synchronized in Java. In fact using the keyword “synchronized” with a constructor is actually a syntax error. 
The “synchronized” keyword is used to prevent 2 or more threads from accessing a group of methods before one thread finishes execution in those methods.

Synchronizing a constructor does not make sense simply because only one thread needs to have access to a constructor. Only the thread that creates an object needs to have access to it while it is being constructed.
when the constructor is called, the object does not even exist yet.
