[英]Java 2D array grid
因此,基本上,我正在嘗試為掃雷游戲制作9x9網格。 我需要在網格中填充問號,以表示尚未選擇的雷區。 例如:[?] [?] [?] [?] [?]基本上,我的問題是如何讓我的程序輸出這樣的問號數組?
import java.util.Scanner;
import java.util.Arrays;
public class H4_Minesweeper {
public static void main(String[] args) {
//Game Description and rules
System.out.println("Minesweeper is a very straightforward game, the rules are simple.");
System.out.println("Uncover a mine (x), and the game ends. Uncover an empty square (o), and you keep playing.");
System.out.println("A question mark (?) will represent tiles you have not uncovered yet.");
System.out.println("Uncover a number, and it tells you how many mines lay hidden in the eight surrounding squares.");
System.out.println("Use this information to carefully choose which squares to click.");
System.out.println("\n\n\n");
Scanner userin;
String[][] board = new String [9][9];
for (int r = 0; r<board.length;r++){
for (int c = 0; c <board.length;c++){
}
}
}
}
首先,必須通過將數組的所有元素設置為"?"
來初始化數組。 :
String[][] board = new String [9][9];
for (int r = 0; r<board.length;r++){
for (int c = 0; c <board.length;c++){
board[r][c] = "?";
}
}
然后可以打印它:
for (int r = 0; r<board.length;r++){
for (int c = 0; c <board.length;c++){
System.out.print (board[r][c] + " ");
}
System.out.println();
}
這應該做。
for (int r = 0; r<board.length;r++){
for (int c = 0; c <board.length;c++){
board[r][c] = "?"; // Initialize the cell
System.out.print("[" +board[r][c] + "]"); // Display the content of cell board
}
System.out.println(); // go to next line
}
用字符串“?”填充2d數組 對於每個網格空間,然后逐行打印出每個數組索引的值
填充數組:
String[][] board = new String[9][9];
for(int y=0;y<9;y++){
for(int x=0;x<9;x++){
board[x][y] = "?";
}
}
顯示行:
for (int r = 0; r<9;r++){
String line = "";
for (int c = 0; c <9;c++){
line+="["+board[c][r]+"]";
}
System.out.println(line);
}
