A company that makes Computer Assisted Design (CAD) software has, within its application, some utilityclasses that are used to perform 3D rendering tasks. The company’s chief scientist has just improved theperformance of one of the utility classes’ key rendering algorithms, and has assigned a programmer toreplace the old algorithm with the new algorithm. When the programmer begins researching the utilityclasses, she is happy to discover that the algorithm to be replaced exists in only one class. The programmer reviews that class’s API, and replaces the old algorithm with the new algorithm, being carefulthat her changes adhere strictly to the class’s API. Once testing has begun, the programmer discovers thatother classes that use the class she changed are no longer working properly. What design flaw is mostlikely the cause of these new bugs?()
