The server responds to the client to choose one of the following options available with server and then deliver the requested object to client o Certificate • Secret Key • Message Digest o Digital Signature • Server Program is first started. • Then the Client program is started. Execute the following steps: Step 1: Run the Java program of Server Step 2: Run the Java program of Client and display the Sample output of Client Window as communicated to the server and response from the server Task: 1. Write the Java socket program for the Server. (class name: Server_Your ID Number) Task: 2. Write the Java socket program for the Client. (class name: Client_Your ID Number) Task: 3.

Server-side ⚫ A console application should be enough, it prints each response to the output window before sending back to the client-side(s). • When it first runs, at least five pre-defined products with random quantities (1-3) should be initialized. Which means products should be the same every time the server starts, and the quantities for each product should be randomized. At least 3 accounts should be created, each account has an account number and user's name. • When the server is active, it should store ordering information to variable(s) (e.g., dictionaries, lists). The server does not have to store the ordering information to the local system, so once you shutdown the server, all information can be disposed. • Server should send back appropriate response depending on the client's command. (Protocol below) • The handler code should be separated from the user interface (i.e., in a separate class - similar to…QUESTION 1 • Develop a server program in Java that waits for clients to connect.

- C++ PLEASE!! Working on a project that is about word count with MapReduce, need a file manager class to take care of reading all txt file from a directory with giving path. The file manager class need to open the directory with the giving path which the user will input, then open the path and open all the txt files in that directory and break the text into single line and pass it to another class to do mapping. Please help with the file manager class!! Thank you!!A fast food restaurant is planning to develop a system to process customer’s orders. The system receives food orders from the users, and stores and processes according to the order in which the users placed the orders. The system can remove an order from the list of orders once the order is complete. The system can also display the order which is currently being processed by the employees. The system displays the list of orders as well. The system displays all these options as a menu of choices to a user and performs the operations according to the user’s selection. (Please see the test runs on the next page). Write a program in C/C++ to develop a simple order processing system for the fast-food restaurant. In your program, you must use queue to store and process customer’s orders. Your program must use a linked list to perform the queue operations. Your output format should be as shown in the test runs (see the next page). Your program must contain the following user-defined…I need a help with my python activity. This requires 2 clients and 1 server. This is a system to support an online math contest. Rule: There are two participants answering at the same time. The host is responsible in starting up the server, after that they wait for the clients. When the two clients are connected, they must send the message: READY to the server. When the server receives the two READY from the clients, the contest starts. The server will display 3 questions one after another which can be answered in 30 secs each. 11+10 = 21 10+22 = 32 10+10 = 20 The participant with most correct answers wins. At the end of the program, the server must show the results. ex: Client1 WINS! 2/3 Client2: 1/3
- The system consists of a database and a servlet to access the database. The database is running on a server and can be accessed via a TCP/IP link. The main program is running on a different server as a Java Servlet. The database has a component to retrieve the query string and return the data and another component to insert data. The database is an “.exe” file. The server has a component to query the user for a search command and another component to submit the query. 1. How do I draw a deployment diagram for the system. 2.

A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types. Task Create two lists of strings – one list for Protocol called valid_protocols, and one list for storing File extension called valid_fileinfo. For this take the protocol list should be restricted to http, https and ftp. The file extension list should be .html, .csv and .docx. Split an input named url, and then use the first…
