Java assignment issues - Is this atomic?

Question

I\'ve got some questions about Java\'s assigment.

• Strings

I\'ve got a class:

public class Test {
 private String s;

 public synchro         


        

Answer 1

Rather than wrapping your HashMap in something to make it synchronized, consider using a java.util.concurrency.ConcurrentHashMap instead.

This is an updated version of HashMap that guarantees "Retrievals reflect the results of the most recently completed update operations holding upon their onset.".
