我试图在java的另一个类中打印用户输入。我制作了一个棋盘，要求用户在棋盘上输入字符串，然后，当这些字符串被打印到屏幕上时，我希望输出是“您已将工件[名称]放置在坐标[坐标]处”。我试图在另一个类中，而不是在主方法中这样做，但我迄今为止尝试的似乎不起作用。这是我的密码。

import java.util.Arrays;
import java.util.Scanner;
public class ChessBoard
{
     public static void main(String[] args)
    {
        char rows = 'a';
        String spot;
        Scanner scanner = new Scanner(System.in);
        String[][] grid = new String [8][8];

        for(int i = 0; i < grid.length; i++, rows++)
        {
            for(int col = 0; col < grid[i].length; col++);
            String input = null;              // will be changed to a valid position
            boolean validCoordinate = false;   // will be true if position is valid
            while ( ! validCoordinate) {
                System.out.println("Enter a coordinate (for example, a5): ");
                input = scanner.next();
                validCoordinate = input.matches("[a-h][1-8]");
            };
            // now we now that the input is valid
            int row = input.charAt(0) - 'a';
            int col = input.charAt(1) - '1';
            String temp = input + " - ";
            System.out.println("Insert your piece:");
            input = scanner.next();
            grid[row][col] = temp + input;
        }
        System.out.println(Arrays.deepToString(grid));
     }
}

所以我想做的是有一个新类，它使用最后一行来打印我前面提到的所需的输出。任何帮助都将不胜感激，谢谢！
编辑：

import java.util.Arrays;
import java.util.Scanner;
public class ChessBoard1
{
    public static  void main(String[] args)
    {
        userInputs input = new userInputs();
        showInput show = new showInput();

        String grid[][] = input.takeInput();
        show.show(grid);
    }
}

public class userInputs
{
    public String[][] takeInput()
    {
        char rows = 'a';
        String spot;
        Scanner scanner = new Scanner(System.in);
        String[][] grid = new String [8][8];

        for(int i = 0; i < grid.length; i++, rows++) {
            for (int col = 0; col < grid[i].length; col++) ;
            String input = null;              // will be changed to a valid position
            boolean validCoordinate = false;   // will be true if position is valid
            while (!validCoordinate) {
                System.out.println("Enter a coordinate (for example, a5): ");
                input = scanner.next();
                validCoordinate = input.matches("[a-h][1-8]");
            }
            ;
            // now we now that the input is valid
            int row = input.charAt(0) - 'a';
            int col = input.charAt(1) - '1';
            String temp = input + " - ";
            System.out.println("Insert your piece:");
            input = scanner.next();
            grid[row][col] = temp + input;
        }
        return  grid;
    }
}

public class showInput {

    public void show(String [][] inputs)
    {
        for(int i=0 ; i<inputs.length ; i++){
            for(int j=0  ; j < inputs[0].length ; j++)
            {
                System.out.println(Arrays.deepToString(grid));
            }
        }
    }
}

我有两个单独的文件userinputs和showinput，但他们说，他们仍然应该在一个单独的文件中声明？
