I have homework to make a custom version of chess which is 6x6 and the pieces move in a specific way. But for now I am trying to figure out how to select a piece and then place it in another location inside the 2d array I have set up and swap the places of the characters. For now I have:
public class Chess {
static final int rows = 7;
static final int columns = 7;
public static void main(String[] args) {
String[][] board = new String[rows][columns];
fillBoard(board);
enterMove();
}
public static void fillBoard(String[][] board){
for (int row = 0; row < 7; row++) {
for (int col = 0; col < 7; col++) {
board[row][col] = " X ";
outerShell(board);
pawns(board);
System.out.print(board[row][col]);
}
System.out.println();
}
}
public static void outerShell(String[][] board){
board[0][0] = " ";
board[0][1] = " A ";
board[0][2] = " B ";
board[0][3] = " C ";
board[0][4] = " D ";
board[0][5] = " E ";
board[0][6] = " F ";
board[1][0] = " 6 ";
board[2][0] = " 5 ";
board[3][0] = " 4 ";
board[4][0] = " 3 ";
board[5][0] = " 2 ";
board[6][0] = " 1 ";
}
public static void pawns(String[][] board){
//whitePawns
board[1][1] = "wDw";
board[1][2] = " wD";
board[1][3] = " wQ";
board[1][4] = " wK";
board[1][5] = " wM";
board[1][6] = " wDw ";
//blackPawns
board[6][1] = "bDw";
board[6][2] = " bM";
board[6][3] = " bK";
board[6][4] = " bQ";
board[6][5] = " bD";
board[6][6] = " bDw";
}
public static void enterMove(){
System.out.println("");
System.out.println("Select the piece you want to move(Example a1) if you want to quit enter: q");
Scanner gameInput = new Scanner(System.in);
String pieceSelect = gameInput.nextLine();
if(pieceSelect.equals("q")){
System.exit(0);
}
switch (pieceSelect){
case "a1":
}
System.out.println(" ");
System.out.println("Now select a finishing position for the piece to move to");
String piecePlace = gameInput.nextLine();
switch (piecePlace){
case "a2":
}
}
}
In the enterMove() section, I am trying to do it with switch but have no idea how to swap two positions in the array. I am not dead set on using switch because I am not sure if it is possible at all. If someone can make a version of this code where by entering the specific coordinates(like a1) selects bDw then entering another coordinate and swapping bDw with the X i am using as an indicator for an empty space and if possible to explain it i'd be grateful.
