This class has a data member list of type Book using the ArrayList collection. Define method add. This method add the any object to list. Define printAll. This method display all the added object in the list. Define printAll. This method display all the added object in the list. · Define int count. This method returns the number of objects added in the list. Define Book search(Object e). This method returns the object being search if not found return null. Define void remove(int index). This method remove the object in a list Add a main method with the following menu:1 – Add 2 – Count 3 – Print4 – Search 5 – Delete 6 - Exit8.12 LAB: Binary search Binary search can be implemented as a recursive algorithm. Each call makes a recursive call on one-half of the list the call received as an argument. Complete the recursive method binarySearch() with the following specifications: Parameters: a target integer an ArrayList of integers lower and upper bounds within which the recursive call will search Return value: the index within the ArrayList where the target is located -1 if target is not found The template provides main() and a helper function that reads an ArrayList from input. The algorithm begins by choosing an index midway between the lower and upper bounds. If target == integers.get(index) return index If lower == upper, return -1 to indicate not found Otherwise call the function recursively on half the ArrayList parameter: If integers.get(index) < target, search the ArrayList from index + 1 to upper If integers.get(index) > target, search the ArrayList from lower to index - 1…
- Write a recursive function named Multiply2 that multiples by 2 and prints each element in a given list. For example: mylist=[1,2,3,4] Multiply2(mylist) prints: 2 4 6 8 Note: the function takes only one parameter, which is the list on which the operation will be performed.Perform the following. 1) Conver the infix expression a/b-c+d*e-a*c into postfix expression and trace that postfix expression for given data a=6, b=3, c=1, d=2 , e=4 .2) A student is asked to develop an application as part of mini project which reverses the order of numbers, such that the number that is placed last in the list will be removed first. The list can hold any number of elements. Implement the following menu based C++program for the same.Write a display function and delete function in the following code: Declare the libraries Declare the struct Node void create (int A[], int n) { int i; struct Node *t, *last; first = (struct Node *)malloc(sizeof(struct Node)); first->data=A[0]; first->next=NULL; last=first; for(i=1;i<n;i++) { t=(struct Node *)malloc(sizeof(struct Node)); t->data=A[i]; t->next=NULL; last->next=t; last=t; } } Write the Delete Function Write the display function int main() { int A[]={10,20,30,40,50}; create(A,5); Delete(first,4); Display(first); return 0; }
- Complete the method loadBuses(String bfile) that reads information bus information from afile (bfile contains the filename) . Each row in the file should trigger the creation of aninstance of bus or an appropriate subclass, according to the data in table 1. All buses createdshould be added to an arraylist. LoadBuses should return the populated arraylist. public ArrayList<Bus> loadBuses(String bfile ) { Scanner bscan = null; ArrayList<Bus> blist = new ArrayList<Bus>(); return blist; }5.22 LAB: Array palindrome (JAVA) Write a program in java that reads a list of integers from input and determines if the list is a palindrome (values are identical from first to last and last to first). The input begins with an integer indicating the length of the list that follows. Assume that the list will always contain fewer than 20 integers. Output "yes" if the list is a palindrome and "no" otherwise. The output ends with a newline. Ex: If the input is: 6 1 5 9 9 5 1 the output is: yes Ex: If the input is: 5 1 2 3 4 5 the output is: no Code starts here: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int[] userValues = new int[20]; // List of integers from input /* Type your code here. */ }}Data structure & Algorithum java program 1) Add a constructor to the class "AList" that creates a list from a given array of objects.2) Add a method "getPosition" to the "AList" class that returns the position of a given object in the list. The header of the method is as follows : public int getPosition(T anObject)3) Write a program that thoroughly tests all the methods in the class "AList".4) Include comments to all source code.
