When an object is made up entirely ofwrappers,collections, orStringBuffers, no customtoString()implementation is required because these objects have already overridden thetoString()method with meaningful representations: publicclassCustomerWrapperCollectionToStringextendsCustomer{privateInteger score;// Wrapper ...
