For programming tasks, we can use an Array or an Array List. Describe when using an Array would be a good choice, and Describe when using an Array List would be a better choice.

in java please.Create a method from the implementation perspective. Create a method where it takes in a linked chain of values and adds them in order to the front. method header:public void addToFront(ANode<T> first)

In java pls! here is some starter code for this problem: public class ThreadingDivisors { public static void main(String[] args) { long start = System.currentTimeMillis(); int maxDivisors = 0; int answer = 0; for (int n=1; n<100000; n++) { int divisors = getNumDivisors(n); if (divisors > maxDivisors) { maxDivisors = divisors; answer = n; } } System.out.println(answer + " has the most divisors (" + maxDivisors + ")"); long end = System.currentTimeMillis(); System.out.println(end - start + " milliseconds"); } public static int getNumDivisors(int n) { int numDivisors = 0; for (int i=1; i<=n; i++) { if (n % i == 0) { numDivisors++; } } return numDivisors; } }

The main question is the entire page labeled Program #1, the little screenshot is for extra steps. The program has to be written in Java.

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()...

Building a histogram. Write a python program to find the number of occurrences of each word in a text file. The first part of the task is to open the file, then create a dictionary to read each word from the file and compute the word's frequency (consider words written in capital letters equal words written in lower case). At the end build two lists, one with each word in the file (call it words_list) and a second list with the number of occurrences of the word in the file (call it words_count). Do not make distinction among words with capital letters. \n",
