- Problem (class MergeSalary)First, write a Java method merge that takes as parameter a non-empty double array representingemployees’ salaries. The method merges the values of every 2 adjacent elements. put themerged values at the beginning of the array, and put 0 in the remaining positions. Suppose thatthe original array will contain an even number of elements.Second, write two java methods readArray(int[]a) and printArray(int[]a) thatreads/writes the elements of an array passed in parameter from/to the standard input/output.Finally, Use the following main method to test your different methods:public class MergeSalary{ private static Scanner input = new Scanner(System.in); public static void main(String[] args) { double[] salaries = new double[10]; System.out.print("Enter 10 salaries: "); readArray(salaries); merge(salaries); System.out.print("Salaries after merge: "); printArray(salaries); }}5. How to find all the leaders in an integer array in java? An element is leader if it is greater than all the elements to its right side. And the rightmost element is always a leader. For example int the array {16, 17, 4, 3, 5, 2}, leaders are 17, 5 and 2..Computer Science 1. Write a generic method named array_prod() that takes an array of a generic type are returns the product of the values in the elements in the array. Make sure that the generic type extends the Number class. The Number class is defined in the java.lang package. 2. Complete the main() method to find the products of the elements in the provided arrays. Print the results in the main method using 3 decimals.
- Nrite a program in Java that reads 10 integers and store them in AN ArrayList. Then, do the following: ) Print the ArrayList in the reverse order b) Sort the ArrayList, and display the data after sorting c) Print the largest and the smallest element in the ArrayListRequirements: Use Java Programming only. Show screenshots of your work. 6. Write method public static int linearSearch(int [] arr, ine key) which returns the largest index such that arr[index] matches the key. If there is match, returns -1. 7. Write method public static double average(int [] arr) which returns the average of all elements in given array arr. Assume that arr has length at least 1. 8. Write method public void crazyPrint(String sentence, int n) which print out the given sentence n times. Assume n is positive integer.In Javascript, write code that prints the FIRST NAMES ONLY of people who have BOTH above average English grades AND below average age. Special conditions: Cannot use any array type built-in functions except filter(), map(), and reduce().
- URGENT JAVA Write a Java method that takes two 2 dimensional int arrays (a and b) and a 2 dimensional boolean array (c) where all three arrays have the same size. Your method should return an array (result) such that, if a partic- ular element in c is true, then the corresponding (same indexed) element in result must be the multiplication of the the corresponding elements of a and b. If the element in c is false, then the the corresponding element in result must be the negative of multiplication of the the corresponding element in a and b. For example ifa = {{1,2,3},{4,5}},b = {{1,2,1},{0,2}} andc = {{true,false,true},{false,true}}, then the result should be result={{1, -4, 3}{0, 10}}.Java - Given a list (44, 80, 96, 33, 15, 42, 73, 99, 91, 77) and a gap array of (5, 4, 1):Requirements: Use Java Programming only. Show screenshots of your work. this is the second time I posted this since the previous answer is very wrong. 6. Write method public static int linearSearch(int [] arr, ine key) which returns the largest index such that arr[index] matches the key. If there is match, returns -1. 7. Write method public static double average(int [] arr) which returns the average of all elements in given array arr. Assume that arr has length at least 1. 8. Write method public void crazyPrint(String sentence, int n) which print out the given sentence n times. Assume n is positive integer.
- JAVA Program ASAP Here is a Sort.java program. Create A FileSorting.java program so it runs and passes the test cases in Hypergrade. import java.util.ArrayList;public class Sort { public static <E extends Comparable<? super E>> void insertionSort(E[] array) { for (int i = 1; i < array.length; i++) { for (int j = i; j > 0 && array[j].compareTo(array[j - 1]) < 0; j--) { swap(array, j, j - 1); } } } public static <E extends Comparable<? super E>> void insertionSort(ArrayList<E> arrayList) { for (int i = 1; i < arrayList.size(); i++) { for (int j = i; j > 0 && arrayList.get(j).compareTo(arrayList.get(j - 1)) < 0; j--) { swap(arrayList, j, j - 1); } } } public static <E extends Comparable<? super E>> void bubbleSort(E[] array) { for (int i = 0; i < array.length - 1; i++) { for…import java.util.Scanner; public class ModifyArray { public swapArrayEnds(10, 20, 30, 40) { for (i = 0; i < (arrVals.length / 2); ++i) { tempValue = arrVals[i]; // Do swap //*please fix code// arrVals[i] = arrVals[arrVals.length - 1 - i]; arrVals[arrVals.length - 1 - i] = tempValue; Write a method swapArrayEnds() that swaps the first and last elements of its array parameter. Ex: sortArray = {10, 20, 30, 40} becomes {40, 20, 30, 10}. public static void main (String [] args) { Scanner scnr = new Scanner(System.in); int numElem = 4; int[] sortArray = new int[numElem]; int i; int userNum; for (i = 0; i < sortArray.length; ++i) { sortArray[i] = scnr.nextInt(); } swapArrayEnds(sortArray); for (i = 0; i < sortArray.length; ++i) { System.out.print(sortArray[i]); System.out.print(" "); } System.out.println(""); }}CODE IN JAVA METHOD TO FIND PAIRS IN AN ARRAY LIST THAT CAN BE MULTIPLIED TOGETHER TO GET PARAMETER Complete the method findPairs which receives an array of integers and an intand returns an ArrayList of instances of Pair (this class is available in theQuestion.java file). You should search the array for any two ints whose product(i.e. when multiplied) is equal to the int parameter. When you find a pair, createan instance of Pair and add it to the ArrayList to be returned. The order of thevariables in the constructor is irrelevant. Do not modify the Pair class. Example 1:Array contains (1, 1, 1, 2, 2, 1, 1, 1)int parameter = 4The ArrayList should contain one instance of Pair with the values (2, 2). Example 2:Array contains (1, 2, 3, 4, 5, 6, 7, 8)int parameter = 12The ArrayList should contain two instances of Pair with the values (2, 6) and(3, 4) Example 3:Array contains (1, 1, 1, 1, 1, 1)int parameter = 3The ArrayList should be empty as there are no ways to compute the product of…
