The following class is used to test board games. Many board games have a start and an end and some type of path or track you have to follow. In order to win the game, the players have to get from the start to the end and usually the faster the better. We will only be concerned with going from the start to the end. Speed is not important. class Board{ private boolean win; private char[][] board; public Board(int rows, int cols, String line){ //part a } //getStart returns a String storing the r and c of S in form "r c" public String getStart() { //code not shown } //getEnd returns a String storing the r and c of E in form "r c" public String getEnd() { //code not shown }private void check(int r, int c ) { //part b } public boolean win() { //part c } }Write the Board constructor method. The Board constructor will receive the number of rows, the number of columns, and the values to be placed in the board. line will store a series of characters. If the Board call new Board(3,3, "W-SE") was made, then the result would be a board of size 3 X 3 that looked as follows ::W - S- - -- - E W represents a wall, - represents a path, S represents the starting location, and E represents the exit. Write the Board constructor below. public Board(int rows, int cols, String line){ }
