我不知道爲什麼，但無論何時您或計算機在我的遊戲中受到一擊，網格都會更新。 玩家和電腦網格是' - '字符的多維數組，當你得到命中時，它變成'x'。在遊戲循環中，他們是一個玩家網格和計算機網格，我在不同的時間單獨更新它們，但是當它們打印出來時它們都是相同的。有人可以幫忙嗎？對不起，我是新手編程基於文本的戰艦遊戲打印兩個相同的網格 - Java
public class Game{
public static void main(String[] args){
Grid grid = new Grid();
Computer computer = new Computer();
Player player = new Player();
String playerGuess;
player.setPlayerShips();
computer.setComputerShips();
char[][] playerGrid= Grid.gridArray;
char[][] computerGrid = Grid.gridArray;
System.out.println("Welcome to BATTLESHIP");
System.out.println("You are to sink your opponents 3 ships, each 3 units in length.");
System.out.println("The ships can be both vertical and horizontal.");
System.out.println("Enter your coordinate guess in the form A1, B5, F6, etc.");
System.out.println("Since the grid is 7x7, coordinates go from A1-G7.");
System.out.println("Letters are vertical, numbers are horizontal.");
System.out.println("You will also have 3 ships placed randomly, which the computer will also try to guess.");
System.out.println("During the game, enter exit if you would like to quit.");
System.out.println();
while(true){
System.out.println("Your Grid");
grid.printGrid(playerGrid);
System.out.println("Opponent's Grid");
grid.printGrid(computerGrid);
System.out.println();
playerGuess=player.getGuess();
if(playerGuess.equals("exit")){
break;
}else{
playerGuess=grid.convert(playerGuess);
}
player.setFirstCo(playerGuess);
player.setSecondCo(playerGuess);
System.out.println();
if(player.isHit(player.firstCo, player.secondCo)){
player.addHits(player.firstCo, player.secondCo);
System.out.println("Hit!");
System.out.println();
computerGrid=Grid.newGrid(computerGrid,player.firstCo,player.secondCo);
}else{
System.out.println("Miss.");
System.out.println();
}
if(player.hasWon()){
System.out.println("Congratulations, you have sunk all your opponents ships!");
break;
}
computer.guess=computer.getGuess();
computer.lastGuess=computer.guess;

我得到了網格單獨打印，但是我的地方船的方法有問題。有人可以看看嗎？假設選擇隨機的x，y座標（每艘船3點），併爲3艘船做這個。它有時連續放4點，沒有其他船（我認爲這些船隻重疊，但我試圖修補）。無論如何，如果你能提供幫助，請提前致謝。

請向我們展示所有相關的代碼。什麼是「Grid」類？似乎你在玩家和電腦的網格中使用了相同的參考'Grid.gridArray'。 – Howard
