Writing Java Program (13 m depicted in the figure below, define one interface named Downloadable and five classes Jocument, TextDocument, HTMLDocument, WebsiteManager and Test. Class HTML Doc extends TextDocument and implements interface Downloadable. Subclass TextDocument extends superclass Document. The two classes have a "composition" relationship (WebsiteManager Array of Document). Class Test contains only main method. 662 Document # title: String #size: double + Document(title:String, size:double) + toString(): String «interface»> Downloadable TextDocument + duration (internetSpeed:int): double #length: int + TextDocument(title: String,size:double.length:int) + toString(): String HTMLDocument HTMLDocment(title:String,size:double,length:int) + duration (internetSpeed:int): double WebsiteManager - serverName: String - documents: Document[] + Website Manger(serverName:String. numberOfDocuments + add (document: Document, index:int):void +NumURLS(): int +totalDurations(internetSpeed:int):double +display()
s Description interface Downloadable: Document: ● ● duration(): takes an internet speed and returns the download duration title: title of this document size: size of this document Document(title:String, size:double): constructor to initialize the title and size with the received parameters. ● toString(): returns a string containing all information of the Document TextDocument: • length: length of text document ● TextDocument(title:String,size:double,length:int): constructor to initialize the title, size, and length with the received parameters. ● toString(): returns a string containing all information of the Text document. HTMLDocument: ● Create a final class called HTMLDocument which is a downloadable text document HTMLDocment(title:String,size:double,length:int): constructor to initialize the title, size, and length with the received parameters. duration (internetSpeed:int):double: return the calculated duration based on the following: the document size divided by the Internet speed, multiplied by length divided by 1000. Website Manager: serverName: name of servers documents: Array of type Document to store list of Document(TextDocument and HTMLDocument). WebsiteManager(String serverName, int numberOfDocuments): constructor to initialize the serverName and numberOfDocuments (size of thr array) with the received parameters. ● add (document: Document, index: int): a method which takes a document and an index, and puts the document at the specified index in the array. Use try-catch statement to handle the ArrayIndexOutOfBounds Exception which occurs when the index is out of range of an array and display an information of that exception. • NumURLS(): returns a number of URLs of all downloadable documents. totalDurations(internetSpeed:int): takes an Internet speed and returns the sum of durations of all downloadable documents. hint: use downcasting. display(): prints all information of documents by calling toString() method.
