Singleton pattern vs Static Class (a class, having all static methods) is another interesting questions, which I missed while blogging aboutInterview questions on Singleton pattern in Java. Since both Singleton pattern and static class provides good accessibility, and they share some similarities e.g...
Assertion found on web: The main difference between static and Singleton classes is that static classes don't ever get initialised. My POV: I don't understand. What about static initializers? --- So, in the end it's not clear for me why one should prefer the Singleton pattern over the ...
Singleton Pattern VS. Static ClassA Singleton implementation affords the ability to implement interfaces, inherit from other classes, and support inheritance itself. In contrast, a static class cannot inherit instance members and lacks such flexibility. Consequently, Singleton exhibits a higher degree of...
In other words, only one, single object of that particular class can be created in a program. Here’s a simple, quick-and-dirty singleton class: public class SimpleSingleton { // Create the single instance, make it available statically, and // don't let it be redefined. private static ...
sealed class Singleton { private Singleton() { } public static readonly Singleton TheInstance = new Singleton(); } As in C++, you can use a private constructor to prevent programmers from creating instances of Singleton. To prohibit inheritance, declare your class sealed. (...
(In C++ you can do this by making all constructors private.) Instead of a static object inside a static GetInstance function, as shown inFigure 1, C# lets you create a read-only static property (in this case, Singleton.TheInstance) initialized to a new instance of the cla...

Since Java 1.3, we have had the static factory method with the name that says it all:Collections::singletonList. 1 1 List<Object>list=Collections.singletonList(item); Developers wishing to save a few keystrokes may be tempted to use theArrays::asListfactory method that has been around since ...
