Java - No enclosing instance of type Foo is accessible

Question

I have the following code:

class Hello {
    class Thing {
        public int size;

        Thing() {
            size = 0;
        }
    }

    public stat         


        

Answer 1

Thing is an inner class with an automatic connection to an instance of Hello. You get a compile error because there is no instance of Hello for it to attach to. You can fix it most easily by changing it to a static nested class which has no connection:

static class Thing
