       String transform(String thePhrase) {
           return thePhrase.toUpperCase();
       }
  

• The transform method for a Pedant is:
  

       String transform(String whatToSay) {
           return "Obviously " + whatToSay;
       }
  

• The entire class for a NameDropper is:

       class NameDropper extends StringTransformer {
  
           String name; // the persistent storage, a permanent part of each NameDropper
  
           NameDropper(String whatMyNameShouldBe) { // Creation rule (constructor)
               this.name = whatMyNameShouldBe;
           }
  
           String transform(String whatToSay) { // Transform rule
               return this.name + " says " + whatToSay;
           }
       }
