Networking and Thread in Java application
Objective:
Server with Multiple Clients
Activity 1:
Write a Java
NOTE : Client must be running until Bye message is sent. Server should never stop
Step by step
Solved in 3 steps with 3 images
- Socket programming The application consists of two parts: Server and Client. Each part can run independently on separate computers. Server manages the chat session. It maintains a list of the active clients and forwards incoming messages. The Server is multithreaded - communication with each client is through a separate thread. When Server is started, it starts to wait for client connections. This thread continues forever to listen for clients. When a connection request is received, the server starts a thread to service the client. This is necessary for each client to have its own socket. When the thread is started, a Client object is created containing all the relevant info about each client and saved in a list. The ServiceClient() thread is where all the work is done. ServiceClient() defines the implementation of the server side of the application protocolThread pool is a term that you should be familiar with.The method area is shared by all running threads in a JVM. Why is it so?
- Multi-threading A) Write a Thread class (called worker) that takes two numbers (A and B, A < B) and calculates the products of all numbers between A and B. the result is stored in a local variable than can be accessed through a get method. ). The main thread reads n from the user, then creates two instances of Worker. Each one is requested to calculate the half of numbers between 1 and n. Once they finish, the main thread will gather their results and print the final result (result1 x result2). Example when n=10Multi-threading A) Write a Thread class (called worker) that takes two numbers (A and B, A < B) and calculates the products of all numbers between A and B. the result is stored in a local variable than can be accessed through a get method. B) Write a main program to calculate the factorial of a given number n (). The main thread reads n from the user, then creates two instances of Worker. Each one is requested to calculate the half of numbers between 1 and n. Once they finish, the main thread will gather their results and print the final result (result1 x result2). Example when n=10Java Programming 2/Mobile Device Programming 2) Threads are a relatively recent invention in the computer science world. Although processes, their larger parent, have been around for decades, threads have only recently been accepted into the mainstream. Perhaps the best example of threading is a WWW browser. Can your browser download an indefinite number of files and Web pages at once while still enabling you to continue browsing? While these pages are downloading, can your browser download all the pictures, sounds, and so forth in parallel, interleaving the fast and slow download times of multiple Internet servers? Discuss about this.
- Java programming language * Make the user able to perform several operations at the same time. * Each Thread that you run works separately from the rest of the commands in the program, and therefore in the event of any error occurring in the Thread, it will not affect the rest of the commands in the program, as it does not affect any other Thread running in the program. In light of your study of multiple channels, • Write a program in the Java language that demonstrates this concept - you can choose the nature of the program that you want to achieveThe method area is something that is shared by all of the running threads in a JVM. Why is this the case?Describe the process of creating and managing threads in Java.
- Hands-on ActivityMovie Time Objective: At the end of the exercise, the students should be able to: ▪ Implement queues in both Java and Python.Software Requirements:▪ NetBeans IDE▪ Java Development Kit (JDK) 8▪ Python 3.7 or higherProcedure:1. Create a folder named LastName_FirstName in your local drive. (ex. Reyes_Mark)2. Using NetBeans, create a Java project named MovieTime. Set the project location to your ownfolder.3. Import Scanner, Queue, and LinkedList from the java.util package.4. Create two (2) Queue objects named movies and snacks.5. The output shall:5.1.Ask the user to input three (3) movies that s/he would like to watch in a cinema.5.2.Ask the user to input three (3) snacks or beverages that s/he would like to eat or drink whilewatching these movies.5.3.Display all the movies and snacks in separate lines.5.4.Ask the user to type S whenever s/he is done eating or drinking a snack.5.5.Display the snacks remaining each time S is pressed and "No more snacks" when all snacksare…THREAD -"C LANGUAGE" ONLY Write a program that uses 5 threads. Initialize a shared variable with a value of 0. Each thread must add its Thread ID (tid) to the shared variable. Once a thread has done the addition, print the ID of the thread. It is important to make use of mutexes so that only one thread is incrementing the shared variable at a time. Output the value of the shared variable once all threads have finished incrementing it.Python Threading help Put the thread_function on a thread. Put 3 threads into a queue and run the threads. import queuequeue = queue.Queue def thread_function(n): print("starting", n) time.sleep(2) print("finishing", n)
