java 代码

package example;

import java.awt.BorderLayout;
import java.io.File;
import java.util.Date;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;

public class TableFeature extends JFrame {

      String[] titles = new String[] {
        "Directory?", "File Name", "Read?", "Write?", "Size", "Last Modified"
      };

      public TableFeature( ) {
        super("Simple JTable Test");
        setSize(300, 200);
        setDefaultCloseOperation(EXIT_ON_CLOSE);

        File pwd = new File(".");
        Object[][] stats = getFileStats(pwd);

        JTable jt = new JTable(stats, titles);
        jt.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
        jt.setColumnSelectionAllowed(true);

        JScrollPane jsp = new JScrollPane(jt);
        getContentPane( ).add(jsp, BorderLayout.CENTER);
      }

        }

      }

      public static void main(String args[]) {
