Actually, java is a object oriented programming language. It is a platform independent.

ach chess piece should be able to: (a) return its current position on the chess board, as methods getRow () and getColumn () (b) return its color as an enum Color (c) determine if it can move to a given cell, as a method canMove (int row, int col), (d) determine if it can kill a provided piece starting from where it currently is, as a method canKill (ChessPiece piece). In addition, each chess piece should have a constructor that takes in an initial position as a row and column, and a color as an enum color with values BLACK and WHITE.

Therefore the "top" row shown on the graphic above (where the Black non-pawn pieces are positioned) is row 7.

Question

How do I code this in Java? (classes for each chess piece, abstract class, interface class and enum class)

What to do
You must design and implement classes that represent the above chess pieces. These classes should be
named exactly as their names above, and all of them should implement the ChessPiece interface. Unlike
previous assignments, we're not explicitly giving the interface code to you; develop the ChessPiece
interface based on the following (NB: ensure your ChessPiece interface is spelled the same way as you see here).
ChessPiece contract:
Each chess piece should be able to:
(a) return its current position on the chess board, as methods getRow () and getColumn ()
(b) return its color as an enum Color
(c) determine if it can move to a given cell, as a method canMove (int row, int col),
(d) determine if it can kill a provided piece starting from where it currently is, as a method
cankill (ChessPiece piece). In addition, each chess piece should have a constructor that takes
in an initial position as a row and column, and a color as an enum color with values BLACK and
WHITE.
Note: All rows and columns begin at "index" 0. Rows decrease in number from top to bottom in the
above chessboard. Therefore the "top" row shown on the graphic above (where the Black non-pawn
pieces are positioned) is row 7.
Beyond the classes, enum, interface and methods specified here, you are free to design any other interfaces
and classes as you see fit. However, they must have good justification, be designed appropriately, and be
used in the appropriate place.
You must write tests for each chess piece! Test your operations thoroughly.
NB: We are not considering the "board setup" with obstruction pieces. This exercise is much simpler than factoring
in "collision detection" with obstructing pieces. Answer the question: it a "is this a valid move for this piece,
assuming there are no other obstructing pieces on the board"? when creating your solution.In other words, given
what you know about the variation in behavior for moves, just determine if the move to a new location is valid. Or,

Introduction
A game of chess has several kinds of pieces: pawns, knights, bishops, rooks, queens and kings. These pieces
are arranged on a chess board as shown in the figure below.
A A 土

A cell on the board is specified by a (row, column) tuple: rows increasing from bottom to top and columns
increasing from left to right. Traditionally the black pieces are arranged in the top two rows as shown.
Each chess piece can move in a specific way. In addition to moving, each chess piece can also kill/capture a
chess piece of the opposite color if it moves to its place. The rules for each chess piece are as follows:
• Bishop: A bishop can only move diagonally, and kill any opponent's piece if it can move to its place.
• Knight: A knight can move only in an L pattern: two cells horizontally and one vertically or vice versa. It
can kill any opponent's piece if it can move to its place.
• Queen: A queen can move horizontally, vertically and diagonally. It can kill any opponent's piece if it can
move to its place.
• Rook: A rook can move horizontally or vertically. It can kill any opponent's piece if it can move to its
place.
• Pawn: A pawn is interesting: it can move only "ahead," not backwards towards where its color started. It
can move only one place forward in its own column. However, to kill it must move one place forward
diagonally (it cannot kill by moving straight).

(JAVA) What is code refactoring? Group of answer choices A)None of the options are correct. B) It is changing implementation of a method or constructor of a class, while leaving the declaration the same, allowing all users of that class to continue using the class without noticing the change. C)It is abstracting a class so that common elements with another class are moved into the abstract class that both classes extend. D) It is declaring all the methods that need to be supported in an interface. This guarantees that all classes implementing this interface will support those methods.

why might we write public get and set methods for private properties? hint: you may want to do a quick internet search for "java getters and setters pros and cons." 1. these public methods give us a way to read and write the values of these properties in a controlled way 2. they make a program run more efficiently 3. if we didn’t, there would be no way to read or write the values of the properties 4. object-oriented languages require us to do this
