How to fill HashMap object only once for program?
java,static,hashmap,instantiation
You can call the getAnimalNameTranslations method from your static initializer block, which would be executed once, when the class is initialized. You'll have to add a static member that holds the Map returned by the method. For example : private static HashMap<String, String> animalNameTranslations; static { animalNameTranslations = getAnimalNameTranslations ();...
Calling a Static Method In Main

Another way to program “static”: Is Code ok?
It's a lot of complication for zero benefit. You can make a singleton instance and throw some inheritance at it, but in the end you cannot whitewash away the fact that you're still calling a static method. Java allows static methods as a way to let you write code that...
Call Javascript function from C# static web method (page method)
javascript,c#,asp.net,static,webmethod
Call the JavaScript function upon successful completion (callback) of the call to the web method in your JS code. You can't "call" client-side code from the code behind; you can register a JS function call as a "startup script" but not here as a call to a web method does...
Is this thread-safe in Java?
Yes, that is thread safe. static initializer blocks are run when the class is initialized and that is done behind a lock. So mySet is initialized fully before it is published (made available). All threads will see it fully constructed.
Using external static library in LPCXpresso
You can easily add a library to Eclipse/LPCXpresso by creating a new project (not a C project or a LPCXpresso project but a 'normal' project) by clicking File->New->Project. Name is as you wish, let's say 'JPEG'. Add your library file to it under the folder 'lib' (you have to create...
Implementing a Command Design Pattern with static methods C#
c#,design-patterns,design,static
Delegates are C#'s built-in implementation of the command pattern. Why re-invent the wheel; use delegates, which support static, pure functions automatically. So you have an event system and those events invoke delegates. You need those delegates to have state though, without creating instances of some class. That's where closures come...
Static interface equivalent C#
c#,inheritance,interface,static
It seems you want to supply some meta-information along with the subclasses of TableRow; meta-information that can be retrieved without instantiating the particular subclass. While .NET lacks static interfaces and static polymorphism, this can (to some extent, see below) be solved with custom attributes. In other words, you can define...
Placing a global constant array into `.rodata` section
There is no portable way to put data into the .rodata section because even the existence of such a section is implementation-dependent.

Creating a static class with no instances
The Pythonic way to create a static class is simply to declare those methods outside of a class (Java uses classes both for objects and for grouping related functions, but Python modules are sufficient for grouping related functions that do not require any object instance).

How do I avoid problems arising from accessing static fields before the class is initialized?
You could keep your immutable list in a separate class, like People.GUYS: public class People { public static final List<Guy> GUYS = ImmutableList.of(Guy.TOM, Guy.DICK, Guy.HARRY); } This way you can still keep the individual guys in the Guy class: public abstract class Person { public static final class Guy extends...
Why are exceptions in a static constructor wrapped in TypeInitializationException
What are the reasons for wrapping the exception in a TypeInitializationException ? Exceptions in static constructors are difficult. Basic issue is that the execution context of the exception is very vague. The CLI does not give any specific promise exactly when the constructor runs. Only guarantee is that it...
Why should we use a List of a particular type in Java

The <> syntax is called generics - it allows you to limit what type of elements a collection holds, and refer to them by this type. It's not required, it's just more convenient. For instance, you could write the second method without any generics specified, but you'd have to handle...

The reason for this is that the compiler doesn't know which exact subtype of AbstractErrorHandler will be replacing T at Runtime.
