The Fork/Join Framework is used for parallel programming in Java. The Fork/Join Framework when illustrated in form of a diagram resembles a fork, hence its name. A problem is divided into nonoverlapping subproblems, which can be solved independently in parallel. The solutions to all subproblems are then joined to obtain an overall solution for the problem. This is the parallel implementation of the divide-and-conquer approach. In JDK 7's Fork/Join Framework, a fork can be viewed as an independent task that runs on a thread. In this task, you are required to write a Java program in NetBeans that implements Parallel programming using the Fork/Join framework. Your program should initially generate 15 million random numbers. This should be read into an array of doubles. Then it should make use of a method that uses this array to calculate the sum of these doubles. Your program should make use of the subclasses in the Fork/Join Framework. Your program should also output the number of processors available

Write a java program named EmployeeRecords that simulates a company’s HR system. Theprogram reads a list of employee ids, names, and salaries from a file a3q1.txt, and stores theinformation in parallel array lists ids, names, and salaries.Sample input (a3q1.txt)132 Dumbledore 90000465 Lupin 60000443 McGonagall 75000124 Snape 70000337 Sprout 62000Your program will prompt the user to make a selection: retrieve an employee record by employeeID or display a salary report.You must include 2 methods:●retrieveEmployeeRecord(...) that accepts the array list of employee IDs and anemployee ID to find, and returns the index of the entry.

The java program ArrayTest.java is intended to do the following: • Fill the array a with integer values input from the file ints.txt. • (Shift-right) Shift the elements of a to the right one position and put the last element of array a in the first position in a (wrap around). Example: if a originally contained (1, 2, 3, 4} then the resulting array a would be (4, 1, 2, 3} What command would be given on the command line to redirect the input to the program ArrayTest to come from the text file ints.txt?

Write a Java program that will allow the user to play a hangman game repeatedly until theychoose to stop. The game should randomly choose a secret word from a pre-set list of wordsfor the user to guess. Store the list of words available for play in an array so you can randomlychoose them by index during game play.During a turn, the user will guess one letter at a time. Each letter in the secret word shoulddisplay as an asterisk until the letter is guessed by the user. When a correct letter is guessed,the letter should be displayed in the correct position in place of the asterisk. The user hangshimself with the 8th wrong guess and loses the game.Make a character array to hold the characters and asterisks representing the word beingguessed. You can change the contents of this array as the letters are guessed and revealed. Inother words, this array can be used to display the current state of the secret word each round.Here is the list of words the game should choose from for the secret…

Write a program RURottenTomatoes.java that creates a 2 dimensional integer array of movie ratings from the command line arguments and displays the index of the movie that has the highest sum of ratings. Ratings range from 1 to 5 (inclusive). The rows of the 2D array correspond to movie reviewers and the columns of the 2D array correspond to movies. The reviewer at index 2 gave movie at index 0 a rating of 4. Take a look at the following example for an explanation on the command line arguments sequenc.  The first argument corresponds to the number of reviewers and the second argument corresponds to the number of movies (the dimensions of the 2D integer array). Following are the movie ratings in a row-major order. This means that the first row is filled first, then the second row, etc. In the example above there are 3 reviewers and 2 movies, and the program displays 0 (zero) because the movie at index zero has the highest sum of ratings (movie 0 has sum of ratings equals to 12 while…

Write a program that uses two classes. The first class is called “dAta” and holds x and y coordinates of a point in 2-d space called p1. The second class is called “cOmpute” and holds an array of two pointers to the “dAta” class. The “cOmpute” class has a function, lOad(float x, float y, int n), which loads x and y coordinate data into the array at index n. It also has a function, sLope(), which computes the slope of the line connecting the two array data coordiantes. It also has a function, pRint(), which prints the slope result to the screen. Implement a divide by zero exception using throw in the sLope() nd/or pRint() function as appropriate. The exception should, when caught, print “Slope calculation error…” to the screen and exit the function. The program should load the array with some example points and print the slope to the screen using the class functions.
