3. Libraries The Android UI toolkit is not thread-safe. What does it mean that the library is not thread-safe and what is true about the Android library? You don't have to worry about where you call the UI toolkit methods from. You can not reliably call operations in the library from more than one thread at a time. The android library does not allow you to call from any thread other than the UI Thread. If you put a lock to protect the code you can call the UI toolkit from anywhere. 4. Application Environments .. It is not uncommon for Windows and Mac applications to stall the user interface thread during network operations. Why is this more of an issue in Android than in those environments? In windows and the Mac you can easily have more than one applicatin open at a time. If a program stalls you can easily go do something else. Android has more of a one-at-a-time usage model, so stalling the interface pretty much stalls the user. O 000

How to create an application class called ImageProcessorApplicationMT and an image processor class called ImageProcessorMT according to below? Exercise 1: The Thread Pool For this exercise you should create your own implementation of a thread pool. In preparation for this exercise, you should change the ImageProcessorMT class so that it implements the Runnable interface. Your thread pool will manage threads that run your new ImageProcessorMTs. The thread pool class itself should also implement Runnable. The thread pool should offer a constructor that receives the size of the thread pool as a parameter. The thread pool has relatively simple functionality. It should be possible to submit a task(i.e. an ImageProcessorMT) to the thread pool. This does not mean that the task will actually run yet, just that the thread pool is aware of it and keeps it in a waiting list. The number of ImageProcessorMTs that are added can exceed the number of threads available in the thread pool. It should…
Prior to this conversation, we said that each JVM thread could only use a single method at a time. What about this circumstance causes you to think this way?
1.)Why is this code not thread safe? 2) What issues could arise if it is not fixed? 3) How you would fix it using what you learned about synchronization? You must write lines of code or fix lines of code that already exist in the file for full credit. mport java.io.ObjectInputStream; import java.io.ObjectOutputStream; import java.io.Serializable; import java.net.ServerSocket; import java.net.Socket; import java.util.ArrayList; import java.util.function.Consumer; import javafx.application.Platform; import javafx.scene.control.ListView; public class Server{ int count = 1; ArrayList clients = new ArrayList(); TheServer server; private Consumer callback; Server(Consumer call){ callback = call; server = new TheServer(); server.start(); } public class TheServer extends Thread{ public void run() { try(ServerSocket mysocket = new ServerSocket(5555);){ System.out.println("Server is waiting for a client!"); while(true) { ClientThread c = new ClientThread(mysocket.accept(), count);…
I have a web server program. It works as follows: the parent thread waits for new client connections. Once a new client connection comes in, the parent thread creates a child thread that services the client connection while the parent thread goes back and waits for more connections. Once the client connection finishes, the corresponding servicing child thread exits. When my code has undergone the usual code review process in my company, it has received major criticisms for being gravely inefficient. Name the optimization technique that I I have neglected to use? Clearly explain the technique and how the technique works and how it would improve the performance of my code.
We've established that each JVM thread can only ever call a single method at a time. What leads you to believe this is true?
Please answer in JAVA PROGRAMMING Q)write code using your name and parents as objects in polymorphism? NOTE:MY NAME IS MEHBOOB ALI Q)MAKE a program in java containing 3 thread classes and their objects should be your name, class number and date of birth. First thread will process without interruption but 3rd thread will wait for 2nd thread to complete its process.? NOTE:MY NAMES IS MEHBOOB ALI,CLASS NO 5,DATE OF BIRTH=16/3/2000
Build a class that extends from the Java FX Application class. Name this class - Thread and it needs to use Runnable. You DO NOT NEED to build any GUI code, just build the code to make the thread work. Have the Thread code just loop and print out “Hello World” 100 times. Build a main method in this class which will instantiate this class and start the Thread.
Could you kindly utilize solely my code as I contributed to its development? I emphasize, please utilize only my code.I attached my code below label my code. The question that I need help with: You need to use the pthread for matrix multiplication. Each threadfrom the threadpool should be responsible for computing only a partof the multiplication (partial product as shown in the above picture –all Ti(S) are called a partical product). Your main thread should splitthe matrices accordingly and create the partial data arrays that areneeded to compute each Ti. You must create a unique task with thedata and submit it to the job queue. You can compute the partialproducts concurrently as long as you have threads available in thethreadpool. You have to remove the task the from queue and submitto a thread in the threadpool. You should define the number ofthreads to be 5 and keep it dynamic so that we can test the samecode with a higher or lower number of threads as needed. When allthe…
Implement the server-side requirements and then provide code snippets for each function with clearexplanation/comments of key statements used.i. Create a thread using extending thread class or implementing runnable interface and implementa run method with explanations of the method usedii. The server will read the employee ID, employee name, number of doses, and vaccination status(unvaccinated, partially vaccinated, and fully vaccinated). The server will then connect to thedatabase and add the inputs as a new recordiii. The server will then calculate the number of unvaccinated, partially vaccinated, and fullyvaccinated employees. The server will then send the results to the client for display.

Try commenting out your thread code and summing all of the integers from 1 to 2000. How long does it take? Now, uncomment that thread code and split your sums into the two portions, How long does it take now? What are some other ways you could improve this code? When the numbers got bigger, what did you notice? What surprised you?
