Error: field name cannot be declared static

Question

public class Application {
    public static void main(String[] args) {
        final class Constants {
            public static String name = \"globe\";
        }
         


        

Answer 1

From the JLS section 8.1.3:

Inner classes may not declare static members, unless they are constant variables (§4.12.4), or a compile-time error occurs.

So you're fine if you just make the variable final:

public class Application {
    public static void main(String[] args) {
        final class Constants {
            public static final String name = "globe";
        }
        Thread thread = new Thread(new Runnable() {
            @Override
            public void run() {
                System.out.println(Constants.name);
            }
        });
        thread.start();
    }
}

Of course this won't work if you need to initialize it with a non-constant value.

Having said all of this, it's an unusual design, IMO. It's very rare to see a named local class at all, in my experience. Do you need this to be a local class? What are you trying to achieve?
