This method has been called by the main method and used the getOrDefault to display the student name based on the student id input argument.The default student name is John Doe which will always be displayed whenever the student id was not found on the student Once we map our value using actionThatTakesResponse() function we execute method getOrElse(). If Try has a Success inside it, it returns value of Try, otherwise, it returns defaultChainedResult. Our httpClient execution was successful thus the isSuccess method returns true.
