我如何将 Java 中的二维数组打印到 Swing / JOptionPane 中的 window

Question

我真的很难过。我无法在任何地方找到如何在 JOptionPane 中将此 table 打印为 window（如 ShowMessageDialog），就像在控制台 the desired output

中打印一样

这是我的代码：

import javax.swing.JOptionPane;
import java.util.*;
public class StarWars {

    public static void main(String[] args) {
        String [][] gridPlayer = new String [6][6];
        Scanner kb = new Scanner (System.in);

        String [] rows = {"A", "B", "C", "D", "E", "F", "G", "H"};

        for (int i = 0; i < 6; i++){
            for (int j = 0; j < 6; j++){

                gridPlayer[i][j] = " ~ ";
            }
        }
        System.out.print("  ");
        for (int i = 0; i < 6; i++){
            System.out.print(" " + rows[i] + " ");
        }
        System.out.println();
        for (int i = 0; i < 6; i++){
            System.out.print(" " + i);
            for (int j = 0; j < 6; j++){
                System.out.print(gridPlayer[i][j]);
            }

            System.out.println();

        }

        JOptionPane.showMessageDialog(null, for (int i));

    }

}

如果有人知道如何执行此操作，我们将非常感谢您的帮助。

P.S。 StarWars class 存在，因为它是家庭作业 ;)

有许多可能的方法，这里是一个：您可以尝试使用 StringBuilder 并使用 html 标签将所有内容放入 JLabel 中：

    StringBuilder sb = new StringBuilder();
    sb.append("<html>");

    String [][] gridPlayer = new String [6][6];
    Scanner kb = new Scanner (System.in);

    String [] rows = {"A", "B", "C", "D", "E", "F", "G", "H"};

    for (int i = 0; i < 6; i++){
        for (int j = 0; j < 6; j++){

            gridPlayer[i][j] = " ~ ";
        }
    }
    sb.append("&nbsp&nbsp");
    for (int i = 0; i < 6; i++){
        sb.append(" " + rows[i] + " ");
    }
    sb.append("<br>");
    for (int i = 0; i < 6; i++){
        sb.append(" " + i);
        for (int j = 0; j < 6; j++){
            sb.append(gridPlayer[i][j]);
        }

        sb.append("<br>");

    }
    sb.append("</html>");

    JOptionPane.showMessageDialog(null, new JLabel(sb.toString()));
