static-members

I want to write es6 class: class SomeClass { static prop = 123 method() { } } How to get access to static prop from method() without use SomeClass explicitly? In es6 it can be done with this.constructor , but in typescript this.constructor.prop causes error " TS2339: Property 'prop' does not exist on type 'Function' ". but in typescript this.constructor.prop causes error "TS2339: Property 'prop' does not exist on type 'Function'". Typescript does not infer the type of constructor to be anything beyond Function (after all ... the constructor might be a sub class). So use an assertion: class

My objective is to have a private static Properties object in my class, to act as defaults when creating other Properties objects needed by my application. The current implementation looks like this: public class MyClass { private static Properties DEFAULT_PROPERTIES = new Properties(); static { try { DEFAULT_PROPERTIES.load( MyClass.class.getResourceAsStream("myclass.properties")); } catch (IOException e) { throw new RuntimeException(e); } } } Looking at it, it works, but it doesn't feel right. How would you do it? There are basically two ways. First way is using the static block as you have

I have a few classes as shown here public class TrueFalseQuestion implements Question{ static{ QuestionFactory.registerType("TrueFalse", "Question"); } public TrueFalseQuestion(){} } ... public class QuestionFactory { static final HashMap<String, String > map = new HashMap<String,String>(); public static void registerType(String questionName, String ques ) { map.put(questionName, ques); } } public class FactoryTester { public static void main(String[] args) { System.out.println(QuestionFactory.map.size()); // This prints 0. I want it to print 1 } } How can I change TrueFalseQuestion class so

Can I use static variables in my web application ? what are the alternatives to static ? When I use static variables in pages and more than one user use the application, it makes conflict data (incorrect data). What are the limits of using static members? Are static members shared in memory? Consider storing your shared variables in the HttpApplication object or in the Cache object. However, if you are trying to store values for each user separately, you should store those values in a Session variable. Static variables inside Asp.Net are shared in the memory space of the w3svc.exe process and
