• Create a new project (name it helloMockito)
• Create a ITranslator interface

i.Make sure ITranslator interface has the following code ii.package org.helloopensource.greetings;

                public interface ITranslator {



                        public abstract String translate(String fromLanguage, String toLanguage, String word);
