Static fields on a null reference in Java

static members (static fields or static methods) in Java are associated with their respective class rather than the objects of this class. The following code attempts to access a static field on a null reference.

public class Main
{
    private static final int value = 10;

    public Main getNull()
    {
        return null;
    }

    public static void main(String[] args)
    {
        Main main=new Main();
        System.out.println("value = "+main.getNull().value);
    }
}

Although main.getNull() returns null, it works and displays value = 10. How does this code work?
