Your Assignment for this afternoon
                is reading Java Source code and Documentation
                
                1) read the Customer class in the Customer Project
                    look at the JavaDocs, including make changes
                    and re-generate the JavaDoc
                     Project menu -> generate JavaDocs
                     the open (right click - open with) Doc -> index.html w/ Web Browser
                     
                2) read the City class in the World Project
                    look at the JavaDocs and generate them
                    
                3) read src/test/java CustomerTest.java
                    this does not have JavaDocs, however it does
                    call code I did not write, so I need to be able
                    to look the JavaDocs for code I did not write
                    
                    Look at the JavaDocs for:
                    
                    import org.apache.commons.lang3.RandomStringUtils; (the class)
                    RandomStringUtils.randomAlphabetic(41); (the method)
                    
                    https://commons.apache.org/proper/commons-lang/apidocs/index.html
                    
                    
                    import org.mockito.Mockito; (the class)
                    sanitizerMock = Mockito.mock(XssSanitizer.class); (a static method)
                    
                    https://javadoc.io/doc/org.mockito/mockito-core/latest/org/mockito/Mockito.html
                    
                    
               4) do the same for the CityTest class   
                   look at the import statements
                   
                   
               5) for both test classes look up the JUnit JavaDocs
                   the CustomerTest uses JUnit 4
                   the CityTest uses JUnit 5
