Thread safety in Singleton
- by Robert
I understand that double locking in Java is broken, so what are the best ways to make Singletons Thread Safe in Java? The first thing that springs to my mind is:
class Singleton{
private static Singleton instance;
private Singleton(){}
public static synchronized Singleton getInstance(){
if(instance == null) instance = new Singleton();
return instance;
}
}
Does this work? if so, is it the best way (I guess that depends on circumstances, so stating when a particular technique is best, would be useful)
