in java fx Write a program that launches 1,000 threads. Each thread adds 1 to a variable sum that initially is 0. You need to pass sum by reference to each thread. In order to pass it by reference, define an Integer wrapper object to hold sum. Run the program with and without synchronization to see its effect. I want it like the picture but can you do the without synchroniazation.

Java Program ASAP Modify this program so it passes the test cases in Hypergrade becauses it says 5 out of 7 passed.

Why do I get this error in my java program? Whenever I print a number greater than the amount of edges, I get an "Exception in thread "main" java.lang.ArrayIndexOutOfBounds" error. Please help. My code as well as the error (the picture with the red circle) are provided in the pictures.

Consider the BadReaderWriter.java program attached with this. The program has three threads, namely, one reader thread and two writer threads, and they all access the same list of numbers. The reader thread reads the list and prints it to the terminal. The writer threads append numbers to the list. At any point in time, if either of the writer threads finds that the list contains n elements, then it appends the number n + 1 to the list. Run this program, examine the output, and identify the problems.Fix these problems by implementing the acquireLock() and releaseLock() methods in the code.

for some reason I keep getting an error Exception in thread "main" java.lang.Error: Unresolved compilation problem: The method append(char) is undefined for the type StringBuilder at StringBuilder.main(StringBuilder.java:19)

Steps to be followed: Create a class called MyThread that extends the Thread class. Declare an instance variable int limitToStop in the MyThread class. Create a parameterized constructor in the MyThread class that takes an int as a parameter to initialize a limitToStop instance variable. Override the run() method in the MyThread class. In the run() method, put a for-loop that goes from 0 to limitToStop. The block associated with the for-loop should print out only the odd numbers. Call Thread.sleep(1000) after every number you print out in the for-loop you created in the previous step. The Thread.sleep(1000) method throws an InterruptedException , which is a checked exception. Therefore, we need to enclose the Thread.sleep(1000) call in a try block. Also, add a catch block associated with the try that catches the InterruptedException and prints out the exception information using the printStackTrace() method. Create a MyThread variable using the new keyword in the main()...
