Step by step
Solved in 2 steps
- Write a Java program that implements parallel programming using the Fork/Join framework. And must make use of the subclasses in the Fork/Join Framework. Step1- The program should initially generate 15 million random numbers. Step2-The generated numbers should be read into an array of doubles. Step 2- Then use a method that uses this array to calculate the sum of these doubles. Step 3-It must then display the sum and it must also output the number of processors available. Lastly, Have a clear screenshoot of code in the IDE and a screenshot of the code running.Write a program which will input an array of integers or create an array of random integers, then recursively use the java fork-join threading to find largest prime numbers in the array data. Assume threshold is 100. Finally display the largest prime number from the main thread.int arr[] = {-2, -4, 8, 4, 3, 3, -9};In Java with this given this array, how would this version of Divide and Conqueror be implemented in this case, specifically?

- Make a java program that facilitates addition, subtraction, multiplication, and division of mixed numbers but this time all of the inputs /outputs may involve fractions, mixed fractions, or a combination. PLEASE HELP ME BUILD THE Fraction Class Points to consider: MixedFraction class must override the operations (add, subtract, multiplyBy, divideBy) inherited from Fraction class to have a different implementation if the MixedFraction object will have a Fraction object as parameter in performing the required operation, On top of that, the inherited operations must also be overloaded to allow a MixedFraction object to accept other parameters such as a whole number or another MixedFraction object. The toString method which is inherited must also be overridden by MixedFraction to have a more appropriate return value. Further formatting must also be considered such that if the result of the operation has a zero value for the whole part, the output should only show the fractional part (ex.…Write a java program to rearrange all the elements of an given array of integers so that all the odd numbers come before all the even numbersWrite a Java program called E2b that will read from StdIn an integer, n, and will set the size of a 2D array to have n rows and n columns. The values in this n x n 2D array must be read from StdIn and the array must be filled in row-major order. For example, if the following input stream was read: 4 1 2 3 4 4 3 2 1 9 8 7 6 5 7 6 4 The 2D array created would be: 1 2 3 4 4 3 2 1 9 8 7 6 5 7 6 4 Include in the program above, code that would print the values in the 2D array beginning with the value in the last row, last column and ending with the value in the 0th row, 0th column, traversing the columns from bottom to top, printing n values in each row of the output. The values in the array do not change. You are simply printing them in a unique order.
