This problem demonstrates the use of the chain of responsibility (COR) design patterns on a Length converter program (LCP) with a GUI. The LCP performs conversion from kilometer to one of the following three units: Mile, Yard, and Foot. Its user interface looks like this. Length Converter 10 Kilometer 6.21371 Mile Convert The input string specifies the amount to be converted and dropdown menu indicates which unit it will convert to. The CoR pattern will be applied to the processing of the input string to generate a number representing the converted amount. The LCP user interface is seen as a client making a request to convert the input to a given unit Three handlers are available, one for each unit (MILE, YARD, FOOT) The resulting processing flow for LCP is shown schematically in the next figure Amount in Converted Kilometer Amount Handler RD Handler |- Deliverables The UML class diagram - A SINGLE MS Word document that includes (i) screenshots showing different execution scenarios (ii) printout of the implementation code. - The code must have graphical user interface to test the functionalit
