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.

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…

Java 1. Implement ArrayUnorderedList<T> class which will extend ArrayList<T> by defining the following additional methods(i) public void addToFront(T element); //Adds the specified element to the front of the list.(ii) public void addToRear(T element); //Adds the specified element to the rear of the list.(iii) public void addAfter(T element, T target); //Adds the specified element after the specified target element.a. Create an object of ArrayUnorderedList<T> class and perform some add, remove, and search operations and finally print the entire Stack.
Please answer the problem in the screenshot. Please use the methods below as a base. The language is in Java. import java.util.*; class HeapMax { // we go with arraylist instead of array for size flexibility private ArrayList<Integer> data; // DO NOT MODIFY THIS METHOD public HeapMax() { data = new ArrayList<Integer>(0); } // insert a new element and restore max heap property public void insert(int element) { } // return max public int getMax() { // remove this line return 0; } // remove max and restore max heap property public int removeMax() { // remove this line return 0; } // heap builder public void build(int[] arr) { } // print out heap as instructed in the handout public void display() { } // you are welcome to add any supporting methods }
Write java program that does the following steps. Part 1: Array list implementation: array list implements list interface plus their own functions. 1. a. Create a ArrayList of type Integer and name it as Grades. b. Create a ArrayList of type String and name it as Students. c. Create a ArrayList of type Double and name it as Results. 2. Add the following values to the array List using add function 30, 40,80 ,100,70,100,10,100,10 Print the size of the array list using size () function. 3.Search for 100 in the array list, if you find it, print a message that “those grades are perfect”. Use only contains function. 4. Repeat the step 3 using equals function. 5. Check if array list is empty or not using isEmpty() function. Print a message if it’s empty and if it’s not empty also. 6. the grade is under 20 which is outlier, remove it from the array list. 7. Print array list using System.out.println() 8. Use indexOf to print index of 80. 9. Use get function. 10. What is the difference between…

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); }}
