Consider class IntArrayStack that has two instance variables: int[] data and int top. Implement an instance method inside the IntArrayStack, called popBottom(),that extracts and returns as output the element at the bottom of the stack. All other elements in the stack must remain unchanged and in the same ord

In  java, Write a method void popMult(int k) for the ArrayBoundedStack class which will pop k items from this. Throw a StackUnderflowException and don't pop anything if there are fewer than k items on this. This is a method of the ArrayBoundedStack class. DO NOT USE ANY OTHER METHODS OF THE ARRAYBOUNDEDSTACK CLASS.

Q1: Write the Java code corresponding to the following UML diagram. The class School implements the interface Building. The method computeArea returns the area of the building as width * length. After that, add a testing class with a main method which defines an arrayList that contains three objects. From the main method, print the area of all the three objects. Building > + computeArea() : double + toString() : String School classroomNum: int width: double - length: double + School(classroomNum: int, width: double, length: double) + computeArea() : double + toString() : String

Java this piece of my code is not working .....I am trying to add Warship with a type or warship , but I keep getting an error ? //add another WarShip instance to the ArrayList. //use a foreach loop to process the ArrayList and print the data for each ship. //count the number of ships that are not afloat. Return this count to main for printing. //In the shipShow method: the number of ships that are still a Float public static int shipShow(ArrayList<Ship> fleetList) { //from the ArrayList, remove the CargoShip that was declared as type Ship. fleetList.remove(2); //Removing ElFaro form the list // review Type casting instanceof | up casting Ship < Warship , subclass is a object of its parents //add warship USS John Warner - add cast by (Ship) new WarShip Ship warship2 = (Ship) new WarShip("USS John Warner", 2015, true, "attack submarine", "United States");   fleetList.add(warship2);   int count= 0; //use a foreach loop to process the ArrayList and print the data for each ship.…

Implement the Solver class. In doing so, you are allowed to define other classes to help you (as well as use “built-in” Java classes or the book’s classes). The point of the solver class is the solve method which takes a board/puzzle configuration represented as a 2D array of booleans and returns a char array containing a minimal sequence of moves that will lead to the solved board (all the cells around the edges being filled). The board configuration is passed in as a 5-by-5 boolean array of Booleans with exactly 16 true cells (filled) and 9 false cells (empty). The solve method then returns an array of characters representing a minimal sequence of moves that solves the puzzle. In other words, if the characters from the returned array are used in order as input to the move method on the Board object representing the initial configuration, the resulting board configuration represents the solved board. Furthermore, the solution must be minimal in the sense that there are no solutions…

Provide a different implementation of ChoiceQuestion. Instead of storing the choices in an array list, the addChoice method should add the choice to the question text. For this purpose, an addLine method has been added to the Question class. /**   A question with multiple choices.*/public class ChoiceQuestion extends Question{   // Add any needed instance variables, but don't store the choices   // The choices should be added to the text of the superclass   /* code goes here */      /**      Constructs a choice question with a given text and no choices.      @param questionText the text of this question   */   public ChoiceQuestion(String questionText)   {      /code goes here */   }    /**      Adds an answer choice to this question.      @param choice the choice to add      @param correct true if this is the correct choice, false otherwise   */   public void addChoice(String choice, boolean correct)   {      /*  code goes here */   } }

The play method in the Player class of the craps game plays an entire game without interaction with the user. Revise the Player class so that its user can make individual rolls of the dice and view the results after each roll. The Player class no longer accumulates a list of rolls, but saves the string representation of each roll after it is made. Add new methods rollDice, getNumberOfRolls, isWinner, and isLoser to the Player class. The last three methods allow the user to obtain the number of rolls and to determine whether there is a winner or a loser. The last two methods are associated with new Boolean instance variables (winner and loser respectively). Two other instance variables track the number of rolls and the string representation of the most recent roll (rollsCount and roll). Another instance variable (atStartup) tracks whether or not the first roll has occurred. At instantiation, the roll, rollsCount, atStartup, winner, and loser variables are set to their appropriate…
