- Given an arraylist of positive integers, write a java method to return the number of rotations to the right inorder to obtain the largest sequence of odd integers. Hint: the largest sequence of odd integers may be obtained after 0<= numRotations <= n-1. where n is the number of elements in the arraylist. Note: Rotating to the right means moving all elements one position to the right, i.e. element at position 0 will move to position 1 and element at position 1 will move to position 2 ... element at position n-1 will move to position 0.How do I sort tiles from least valuable to most valuable? import java.util.ArrayList;class Rack{private ArrayList<Tile> Tile;public Rack(){Tile = new ArrayList<Tile>();}public void addTile(Tile t){Tile.add(t);}public String toString(){String str = "";for(int i=0; i < Tile.size() ; i++)str = str + Tile.get(i);return str;}public void sortHighToLow(){int i, j, min;int n = Tile.size();for (i = 0; i < n-1; i++){min = i;for (j = i+1; j < n; j++){if(Tile.get(j).compareTo(Tile.get(min)) < 0)min = j;}//Swap.Tile t = Tile.get(min);Tile t1 = Tile.get(i);Tile.set(min, t1);Tile.set(i, t);}}}class Main{public static void main(String[] args){Rack craigTiles = new Rack();craigTiles.addTile(new Tile('H', 4));craigTiles.addTile(new Tile('E', 1));craigTiles.addTile(new Tile('L', 1));craigTiles.addTile(new Tile('L', 1));craigTiles.addTile(new Tile('O', 1));craigTiles.addTile(new Tile('Z', 10));craigTiles.addTile(new Tile('Y',…Write a program in java that randomly fills in 0s and 1s into an n-by-n matrix, prints the matrix, and finds the rows and columns with the most 1s.

- Two sorted lists have been created, one implemented using a linked list (LinkedListLibrary linkedListLibrary) and the other implemented using the built-in ArrayList class (ArrayListLibrary arrayListLibrary). Each list contains 100 books (title, ISBN number, author), sorted in ascending order by ISBN number. Complete main() by inserting a new book into each list using the respective LinkedListLibrary and ArrayListLibrary insertSorted() methods and outputting the number of operations the computer must perform to insert the new book. Each insertSorted() returns the number of operations the computer performs. Ex: If the input is: The Catcher in the Rye 9787543321724 J.D.
