Part 1. Given the following UML diagram. Answer the following questions. Server Data Center -types:String //for example types="Web#FTP" -name: String -numOfConnectedUsers:int -server: Server +Server(types: String) + DataCenter (name: String) +getTypes():String +getServer():Server +getNumOfConnectedUsers():int +getName(): String +setNumOfConnectedUser(int n): boolean +setName(name: String): void +toString(): String +setServer(server:Server) :void +toString(): String +searchForType(String t):boolean Question 1 (15 pts): Implement the class Server. A server has two types. For example: It can be a Web server and an FTP server. The two types of the server are separated by '#' in the attribute types. In this question, you are required to declare all the attributes and define all the methods (constructor, getters, setter...etc.) as presented in the UML diagram. The attribute numOfConnectedUsers has an initial value 0, and its maximum value is 100. setNumOfConnectedUser(int n); It sets the number of connected users to n. It returns false if numOfConnectedUsers is greater or equal to 100. Otherwise, it returns true. toString() method returns the description of a Server object. For example, The server types are Web#FTP. It has 7 connected users Question 2 (15 pts): Implement the class Data Center that has a composition relationship with the class Server. In this question, you are required to declare all the attributes and define the methods (constructor and getters) as presented in the following UML diagram. Part 2. Question 1. (15 pts) Continue the implementation of Data Center class. Implement the following methods: 1. SetServer(s: Server): This method sets the Servers to the DataCenter. 2. setName(name: String): This method sets the name to the DataCenter. Question 2. (20 pts) Implement the following methods of class DataCenter: 1. toString(): It returns the description of the DataCenter including the name and its Server's description. 2. searchForType(String t): It searches if the server object has the type t (check the attribute "type" and use split method). Question 3. (15 pts) Implement the driver class as follows: 1. Create a DataCenter object which data are given by the programmer (Not from the user). 2. Create a Server object and set it to the DataCenter object created in the previous question (data from the programmer as well). Part 3. Continue the implementation of the driver class: Question 1 (20 pts): Write the code to: 1. Access the number of connected users from the DataCenter object and display its value. 2. Increment the number of connected users by four. 3. Display the description of the DataCenter object. 4. Change the name of the DataCenter (data from the programmer as well)
