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); }}Array lists are objects that, like arrays, provide you the ability to store items sequentially and recall items by index. Working with array lists involves invoking ArrayList methods, so we will need to develop some basic skills. Let’s start with the code below: import java.util.ArrayList;public class ArrayListRunner{ public static void main(String[] args) { ArrayList<String> names = new ArrayList<String>(); System.out.println(names); }} The main method imports java.util.ArrayList and creates an ArrayList that can hold strings. It also prints out the ArrayList and, when it does, we see that the list is empty: [ ].Complete the following tasks by adding code to this skeleton program. If you are asked to print a value, provide a suitable label to identify it when it is printed.a) Invoke add() to enter the following names in sequence: Alice, Bob, Connie, David, Edward, Fran, Gomez, Harry. Print the ArrayList again.b) Use get() to retrieve and print the first…
- 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…1.

- Nedd help in this. Must be in java. make the code unique and no plagerism. write a program that prints out the lists in main after the following methods are called. removeOddLength: Takes an ArrayList of strings as a parameter and removes all of the strings that have an odd length (number of characters), from the list. Return the ArrayList to main and print. swapPairs: Takes an ArrayList and switches the order of values of strings in a pairwise fashion. Your method should switch the order of the first two values, then the next two, then the next two and so on. If the number of values in the list is odd, the method should not move the final element. For example, if the list stores [“madam”, “I”, “am”, “your”, “adam”] your method should change this lists content to [“I”, “madam”, “your”, “am”, “adam”] Return the ArrayList to main and print. intersect: Accepts two sorted ArrayList of integers as parameters and returns one containing only the elements that are found in both.

Every day a new array is produced using the array of the previous day. On the n’th day, the following operations are performed on the array of day n – 1 to produce the array of day n: -If an element is smaller than both left and right neighbor, then this element is incremented -If an element is bigger than both its left neighbor and its right neighbor, then this element is decremented. -The first and last elements should never change Eventually after some days the array will not change, some examples: Example: Input from user: ar = [6,2,3,4] Output from program: [6,3,3,4] After the first day the array is changed from [6,2,3,4] to [6,3,3,4] and no further operations may be completed. Example: Input from user: ar = [1,6,3,4,3,5] Output from program: [1,4,4,4,4,5] After the first day the array is changed from [1,6,3,4,3,5]…
