Update the program / make a simple chat program so that Client can send/receive multiple messages to server. A special exit message is used to disconnect ‘Exit’. Each time client sends a message, server responds with a confirmation of receiving it and its length (use the screenshots in the presentation as a reference)
- Solve with java : Write a Server-Client application that Server provides the page number information of the requested section in the book while the section is requested by the Client. Part I Write method for searching the page number of the requested section.Part II Write Server side class for waiting Client to ask a section and responding itspage number.Part III Write Client side class for requesting a section from Server.Implement the DBS Share Price Index System in Python as per Figure 2 below which allows users toadd, delete, update and lookup Share Prices. The System should store the Company Name and SharePrice. Your program should not allow users to add the same company more than once. On adding,deleting, updating or looking up a Share Price, your program should let the user know if theoperation was successful or not. On looking up a Share Price return the Company Name and SharePrice of the company; if the company is not found give the user the option to add the details theyare looking up. The user can perform multiple actions; they can add a new entry and subsequentlydelete an entry without having to stop and start the program until they decide to quitYou get a job working for the Cerulean City Gym. A previous coder group implemented a client-server program where multiple clients would send message to the server using a single pipe. It worked quite well for years. Now, the requirements have changed and a different group of programmers came in and made some changes. Now, the data being received at the server end is now garbled. The new programmers weren't able to resolve the issue keeping to the original pipe design. Discarding the pipe approach, how would you fix this situation? Based on what you've learned in class, what IPC method would you use to fix this situation?
- The execution of the session design pattern in an online application could look something like this: The Session class in this example is built as a singleton and has methods for logging in and out, verifying the state of verification, and obtaining the user.The class has a static way for locating the sole instance as well as a private function Object() { [native code] } that makes sure no more than one instance of the class can be made.In this manner, the user's login state can be checked, their user object can be retrieved, and their session can be maintained throughout the application by accessing the session object from anywhere in the application.The fingerprint-based voting application can recognize users based on their fingerprint patterns. Since fingerprint authentication is unique for each person, the system can quickly identify the voters using their fingerprints. Naturally, a voter can vote for a candidate only once. The Admin adds all the names and photos of the candidates nominated for the election. The Admin then authenticates users by verifying their identity proof, and after verification, the voter is registered in the system. Furthermore, the Admin even enters the data when the election will end, after which the system will automatically delete the names and photos of the candidates and voters. The users can log in to the system via the unique user ID and password given by the Admin and then use their fingerprints to vote for their preferred candidate. Once the election is over, and the votes are counted, Both the Admin and users can view the election result using the election ID. In the capacity of a System…Imagine you get a data set from a client that contains addresses from 150 countries all around the world and your task is to verify them, the data is stored in 3 fields – Address Line, City, ZIP code. What you also have available is address verification solution for each country, but the data set does not include the country code. Your task is to design logic that will process the data and find the country for each record, so they can be run through a validation component. Think of the most efficient way.
- Consider a sloppy web application for an online shopping site that saves the price of each item as a hidden form variable on the web page given to the client; when the customer submits the form, the information from the hidden form variable is utilized to calculate the customer's bill. What is the flaw in this strategy? (A loophole was used by certain consumers of an online-shopping site before the issue was discovered and remedied in a genuine case.)Suppose you have two columns, [Text1] and [Text2], in a MS Access table, how do you enforcethat only one of them can have a value?A) Apply the validation rule to either [Text1] or [Text2] column: ([Text1]="" And [text2]<>"") Or ([Text1]<>""And [text2]="" B) Apply the validation rule to either [Text1] or [Text2] column: ([Text1]="" And [text2]!="") Or ([Text1]!=""And [text2]="" C) Apply the validation rule to the table: [Text1] or [Text2] column: ([Text1]="" And [text2]!="") Or([Text1]!="" And [text2]="" D) Apply the validation rule to the table: ([Text1]="" And [text2]<>"") Or ([Text1]<>"" And [text2]="" E) none of the aboveHow to remove the item from the cart if the quantity is 0?
