Shared or Static – Visual Basic vs Java?

MP900386814 In Java there are 2 fundamental concepts that any developer should know: instances and classes. Class its the base of your code, your specification about an entity, like Account, Customer or Supplier. Instance its what you get after a “new ” (an object in the heap). So you have at maximum 1 class and N instances of that class.

Although a class its just the specification, in Java a class could have state and behavior like an instance, but with the condition “There could be only one” shared for all instances! Everything that are declared as static are executed(static blocks for instance)/initialized at class load time by the JVM, the rest (instances) are executed/initialized in runtime, after load time.

This word, static comes from very long time, since C, C++, C# and others, but Visual Basic uses other word “shared which somehow implies the behavior of the fields declared as static(java) or shared(visual basic) after a Class “is running”! After the JVM has loaded your class, every static(java) field are shared(visual basic) between all instances, so the question is:

What of these words captures better this behavior (of static) “static” vs “shared”?

So, although I really like a lot languages like C++, Java and C#, I must admit Visual Basic its somehow more expressive and more closely related with the true meaning of “shared” fields!
