What is the difference between a static and a dynamic method?

In X++, the difference between a static and a dynamic method is related to the way that the method is called and the context in which it runs.

A static method is a method that is called on the class itself, rather than on an instance of the class. It does not have access to the instance variables of the class and it cannot be overridden. A static method can be called directly on the class, without the need to create an instance of the class first. Here's an example of a static method in X++:

class MyClass
{
    static int myStaticMethod()
    {
        return 42;
    }
}

A dynamic method is a method that is called on an instance of the class, rather than on the class itself. It has access to the instance variables of the class and it can be overridden. A dynamic method can be called on an object of the class, after creating an instance of the class. Here's an example of a dynamic method in X++:

class MyClass
{
    int myDynamicMethod()
    {
        return 42;
    }
}

It's worth noting that, in X++, the static methods are identified by the keyword static before the return type of the method. Also, static methods can be called directly on the class and do not require an instance of the class, whereas dynamic methods are called on an instance of the class and have access to instance-level data.

It's also worth noting that, when working with static methods, it's important to keep in mind that they cannot access non-static members of the class, and that they can only access other static members of the class.
