[java] How do servlets work? Instantiation, sessions, shared variables and multithreading

if u want to make it Servlet as Thread safe ., U can go for

methods

or we can go for synchronize methods

we can make whole service method as synchronized by using synchronized

keyword in front of method

Example::

public Synchronized class service(ServletRequest request,ServletResponse response)throws ServletException,IOException

or we can the put block of the code in the Synchronized block

Example::

Synchronized(Object)

{

----Instructions-----

}

I feel that Synchronized block is better than making the whole method

Synchronized
