Creation of complex converters. a In this scenario, three existing formats (A, B, and C) and two converters (A2B and B2C) are considered. Each of the A, B and C classes represents a different format and implements the interface GeneralModel. The converters extend the GeneralConverter class and translate from A to B, and from B to C respectively. b A new converter A2C translating from A to C, can be added effortlessly by invoking the method convert() implemented in the converters A2B and B2C. c Java source code illustrating the implementation of the method convert() for the converter class A2C
