Question

I have two classes, and want to include a static instance of one class inside the other and access the static fields from the second class via the first.

This is so I can have non-identical instances with the same name.

Class A  {     public static package1.Foo foo; }  Class B  {     public static package2.Foo foo; }   //package1 Foo  {     public final static int bar = 1; }  // package2 Foo {     public final static int bar = 2; }  // usage assertEquals(A.foo.bar, 1); assertEquals(B.foo.bar, 2); 

This works, but I get a warning ‘The static field Foo.bar shoudl be accessed in a static way’. Can someone explain why this is and offer a ‘correct’ implementation.

I realize I could access the static instances directly, but if you have a long package hierarchy, that gets ugly:

assertEquals(net.FooCorp.divisions.A.package.Foo.bar, 1); assertEquals(net.FooCorp.divisions.B.package.Foo.bar, 2);

I agree with others that you’re probably thinking about this the wrong way. With that out of the way, this may work for you if you are only accessing static members:

public class A {     public static class Foo extends package1.Foo {} } public class B {     public static class Foo extends package2.Foo {} }
