java - 线程 "AWT-EventQueue-0"中的异常 java.lang.ArrayIndexOutOfBoundsException : 1

Question

我一直在努力调试这个异常:Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 1
这是我的代码

package com.Homework.Table;

import java.awt.BorderLayout;
import java.awt.Container;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;

public class ArrayTable  {
    static String [][] records;

    public static void main(String [] args)
    {
        String [] columns= { "col1", "col2", "col3","col4" };
        String array ="A&B&1&May 8 2011 12:17AM;;E&D&5&May 8 2011 12:43AM;;F&G&5&May 8 2011 7:06AM;;H&I&1&May 14 2011 11:57PM";
        records=to2dim (array ,";;","&");
        Object rows[][] =records;
        JFrame f = new JFrame("JTable Sample");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Container content = f.getContentPane();
        JTable table = new JTable(rows, columns);
        JScrollPane scrollPane = new JScrollPane(table);
        content.add(scrollPane, BorderLayout.CENTER);
        f.setSize(300, 200);
        f.setVisible(true);
    }

    public static String [][] to2dim (String source , String outerdelim, String innerdelim) {
        String [][] result = new String [source.replaceAll ("[^" + outerdelim + "]", "").length () + 1][]; 
        int count = 0;
        for (String line : source.split ("[" + outerdelim + "]"))
        {
            result [count++] = line.split (innerdelim);
        }
        return result;
    }
}

import java.awt.BorderLayout;
import java.awt.Container;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import java.util.Arrays;
public class ArrayTable  {
    static String [][] records;

    public static void main(String [] args)
    {
        String [] columns= { "col1", "col2", "col3","col4" };
        String array ="A&B&1&May 8 2011 12:17AM;;E&D&5&May 8 2011 12:43AM;;F&G&5&May 8 2011 7:06AM;;H&I&1&May 14 2011 11:57PM";
        records=to2dim (array ,";;","&");
        Object rows[][] =records;
        JFrame f = new JFrame("JTable Sample");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Container content = f.getContentPane();
        JTable table = new JTable(rows, columns);
        JScrollPane scrollPane = new JScrollPane(table);
        content.add(scrollPane, BorderLayout.CENTER);
        f.setSize(300, 200);
        f.setVisible(true);
    }

    public static String [][] to2dim (String source , String outerdelim, String innerdelim) {

        String [][] result = new String [(source.split (outerdelim)).length][];
        int count = 0;

        System.out.println("result len "+result.length);
        for (String line : source.split (outerdelim ))
            {
                result [count++] = line.split (innerdelim);
            }

        System.out.println(Arrays.deepToString(result));
        return result;
    }
}

这应该对你有用。 [;;]仅匹配单个字符，因此基于此拆分将在两个连续的 ; 之间添加空格.所以应该改为 ;; .
