singleton pattern in java- lazy Intialization
- by flash
public static MySingleton getInstance() {
if (_instance==null) {
synchronized (MySingleton.class) {
_instance = new MySingleton();
}
}
return _instance;
}
1.is there a flaw with the above implementation of the getInstance method?
2.What is the difference between the two implementations.?
public static synchronized MySingleton getInstance() {
if (_instance==null) {
_instance = new MySingleton();
}
return _instance;
}
I have seen a lot of answers on the singleton pattern in stackoverflow but the question I have posted is to know mainly difference of 'synchronize' at method and block level in this particular case.
