Question

我一直在尝试将我的数组加载到一个没有运气的JTable对象中。所以这是我的数组：

int[][] board = {
    {0, 0, 0, 0, 2, 0, 0, 0, 0},
    {0, 0, 5, 0, 0, 0, 0, 2, 4},      
    {1, 0, 0, 4, 0, 0, 0, 3, 8},
    {0, 0, 0, 6, 0, 0, 0, 0, 7},
    {0, 0, 4, 5, 3, 8, 9, 0, 0},
    {8, 0, 0, 0, 0, 7, 0, 0, 0},
    {7, 4, 0, 0, 0, 6, 0, 0, 1},
    {6, 1, 0, 0, 0, 0, 3, 0, 0},
    {0, 0, 0, 0, 9, 0, 0, 0, 0}

我去了http://docs.oracle.com/javase/tutorial/uiswing/components/table.html 并且没有用于放置int数组的构造函数，但是有主题。

任何人都知道一种方法，谢谢！

Answer 1

你可以这样做：

Integer[][] board = new Integer[][]{
        {0, 0, 0, 0, 2, 0, 0, 0, 0},
        {0, 0, 5, 0, 0, 0, 0, 2, 4},      
        {1, 0, 0, 4, 0, 0, 0, 3, 8},
        {0, 0, 0, 6, 0, 0, 0, 0, 7},
        {0, 0, 4, 5, 3, 8, 9, 0, 0},
        {8, 0, 0, 0, 0, 7, 0, 0, 0},
        {7, 4, 0, 0, 0, 6, 0, 0, 1},
        {6, 1, 0, 0, 0, 0, 3, 0, 0},
        {0, 0, 0, 0, 9, 0, 0, 0, 0}};

new JTable(board, new String[]{"columnName1"...});

我在这里看到两种可能性：zou可以使用Integer[][]代替int[][]，可以将其转换为Object[][]，这将与JTable一起使用或者您可以编写自己的数据模型。

根据您最终想要达到的目标，您应该选择更合适的一个。

尝试将int数组更改为Integer数组

请试试这个

import javax.swing.*;
import java.awt.*;
public class JTableComponent{
  public static void main(String[] args) 
{
  new JTableComponent();
  }

  public JTableComponent(){
  JFrame frame = new JFrame("Creating JTable Component Example!");
  JPanel panel = new JPanel();
  Integer[][] board = {
            {0, 0, 0, 0, 2, 0, 0, 0, 0},
            {0, 0, 5, 0, 0, 0, 0, 2, 4},      
            {1, 0, 0, 4, 0, 0, 0, 3, 8},
            {0, 0, 0, 6, 0, 0, 0, 0, 7},
            {0, 0, 4, 5, 3, 8, 9, 0, 0},
            {8, 0, 0, 0, 0, 7, 0, 0, 0},
            {7, 4, 0, 0, 0, 6, 0, 0, 1},
            {6, 1, 0, 0, 0, 0, 3, 0, 0},
            {0, 0, 0, 0, 9, 0, 0, 0, 0}};

   String col[] = {"1","2","3","4","5","6","7","8","9"};
  JTable table = new JTable(board,col);
  panel.add(table,BorderLayout.CENTER);

frame.add(panel);
  frame.setSize(800,500);
  frame.setVisible(true);
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  }
