19. Cloneable interface example

• A Product class implementing the Cloneable interface:

  
      public class Product implements Cloneable
      {
          private String code;
          private String description;
          private double price;
  
          // the code for the constructor and methods
  
          @Override
          public Object clone()
              throws CloneNotSupportedException
          {
              // invoke Object.clone()
              return super.clone();
              //NOTE:
              // Object.clone() method performs a "shallow copy" of the
              // object, not a "deep copy" operation.
              // Therefore, it may be necessary to modify one or more fields
              // of the object returned by super.clone() before returning it.
          }
      }
