1.Identify the problem within this snippet of Java/C# code. (This is not a trick question � there is a potential real problem in using this code)
class Singleton
{
public static Singleton Instance() {
if (_instance == null)
_instance = new Singleton();
return _instance;
}
protected Singleton() {}
private static Singleton _instance = null;
}
