Concurrent access to static methods

Question

I have a static method with the following signature:

public static List processRequest(RequestObject req){
  // process the request obje         


        

Answer 1

All your calls to the method will be executed concurrently... but:

You may have concurrency issue (and being in non thread-safe situation) as soon as the code of your static method modify static variables. And in this case, you can declare your method as synchronized

If your method only use local variables you won't have concurrency issues.
