我不知道为什么，但是每当您或计算机在我的游戏中受到打击时，网格都会更新。播放器和计算机网格是“-”字符的多维数组，当您受到打击时，它会变为“x”。在游戏循环中，它们是玩家网格和计算机网格，我在不同的时间分别更新它们，但是当它们被打印时，它们都是相同的。有人可以帮忙吗？对不起，我是编程新手
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");

break;

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;

computer.addHits(computer.guess[0],computer.guess[1]);
System.out.println("Computer has hit!");

我让网格分开打印，但我的地方船方法有问题。有人可以看看吗？假设选择随机 x,y 坐标（每艘船 3 个点）并为 3 艘船执行此操作。它有时会连续放置 4 个点，没有其他船只（我认为船只只是重叠，但我试图修复）。无论如何，如果您能提供帮助，请提前致谢。
