مشكلة فى ربط 2 class

هنا و فى هذا المثال كنت أجرب ال JPasswordField

لدينا 2 class فى ال class PassWordDilaog أقوم بعمل منادة للدالة getField() من ال class PasswordTest

و لعمل هذه المنادة قمت بكتابة

passwordField = new JPasswordField();

فى الclass PassWordDilaog و لكنه يعطينى خطأ Exception in thread "main" java.lang.StackOverflowError
