First, write a Java method merge that takes as parameter a non-empty double array representing employees' salaries. The method merges the values of every 2 adjacent elements. put the merged values at the beginning of the array, and put 0 in the remaining positions. Suppose that the original array will contain an even number of elements. Second, write two java methods readArray (int[] a) and printArray (int[]a) that reads/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); } } Hint: For the method merge, you can work on the same array or use a temporary array. Run: Enter 10 salaries: 1000 1000 2000 2000 3000 3000 4000 4000 5000 5000 Salaries after merge: 2000.00 4000.00 6000.00 8000.00 10000.00 0.00 0.00 0.00 0.00 0.00

Write program java Create 2D array 4 *5. Ask the user to enter the number inside the array. Print the numbers organized by rows. Calculate the average for each row. Print the least average. Finally, create a method that receives a 2D array to print its elements reverse starting from the last element.

Write a Java program tat prompts user for a list of integers with 0 as the last value.Save the values in an array. Assume there can be maximum 100 values. Theprogram should have the following methods:- A method that takes the array as parameter and updates each value in thearray to the square of the value.- Another method that takes the original and modified arrays as parametersand displays the original and the squared values.
Write in java code Create an array myArr of 10 integer elements and initialize/fill it with numbers (not sorted) between 0 and 20; for example myArr = [ 12, 3, 19, 5, 7, 11,….etc.]. (a) print the array. (b) Use method sort() of class Arrays to sort myArr and print it after sorting. (c) Use the arraycopy() method of class System to copy myArr to another array called my2ndArr, then print both arrays. (d) use method equals() of class Arrays between the two arrays and print the results. (e) use method fill() to fill my2ndArr with 99 in all elements and then use method equals()and print the result whether the two arrays are equal or not. (f) use the method binarySearch() to search myArr for the value 15 and print the result

Write in Java. Given an array of integers A, find the Majority Element. Majority Element in an array of size N in an element that appears more than N/2 times. Write a function: int findMajority(int[] A) that accepts an array A. The function should return the Majority Element in the array. If no majority element then return 0. Use following methods to solve the problem: int findCandidate(int a[]) that accepts the array and find a candidate for the majority boolean isMajority(int a[], int cand) that accept the array and the candidate element and check if the candidate occurs more than n/2 times Input: 5 1 2 1 2 2 Where, First line represents the size of an array. Second line represents array elements separated by single space. Output: 2 Here for the given array, 2 appears 3 times in the array of size 5. No space after the element in the output. Assume that, N is an integer within the range [1 to 10000]. Array elements are within the range…
Write the method printTail() method that accepts an array of integers and an integer index as parameters and prints all the array elements starting from the index passed. For example if printTail(x,5) is invoked, it should print all the elements of the array x starting at x[5].
Make sure each program has at least one method in addition to its driver method(main). Or use one driver main method and write method(s) for each of the program. Write a java program which reads in a hard coded integer array and then display the maximum and minimum value of the array and their indexes. If multiple values are candidates displaying just one and its index is fine. e.g: double [] myList = {1, 5, 5, 4, 3, 0, 5, 5, 1}; 1 and 5 and their indexes works.

Programming exercise (in java eclipse, please add comments for each step). Write a complete Java program named FindProduct that contains the following: a. A main method asks the user to provide the number of rows and columns for a 2-dimensional array of integers. b. A main method calls the getArray() method that creates the 2D array of specified size and populates it with random values from 0 to 100. c. A main method prints the elements of the 2D array created by getArray(). d. A main method calls the printProduct method that will: i. Receive the two-dimensional array as input ii. Calculate the product of elements in each row of the array iii. Display the product on the Console. The product of all elements in each row should be formatted as "Row 1 Product XXXX"
