我想在JFram上显示一个数组，并对这个数组进行排序，请高手帮我改一下我写的程序。
import java.io.*;
import java.text.*;
import java.util.*;
import javax.swing.*;

public class SortIt extends JFrame {

public static void main(String args[]) {

// Create frame to display sortings
JFrame frame = new JFrame( "Sorting ");
setSize(400,300);
addWindowListener(new WindowAdapter()
{ public void windowClosing(WindowEvent e)
{ System.exit(0);
}
} );
JTextField TextField1 = new JTextField();
private JButton Button = new JButton( "排序 ");
JTextField TextField2 = new JTextField();

String st =TextField1.getText();

// Create initial list to sort
StringTokenizer st = new StringTokenizer( "123 234 345 ", " "); // 以空格来分隔数字
int[] array = new int[20]; // 这里最好是先经过st中的数字个数来计算,简单起见直接给个20
int index = 0;
while (st.hasMoreElements()) {
array[index++] = Integer.parseInt(st.nextToken());
}

Button.addActionListener(
new ActionListener()
{ public void actionPerformed(ActionEvent event)
{
Arrays.sort(array);
TextField2.setText()= Arrays.asList(array) ;}
});



frame.pack();
frame.show();
}
}
但是不对，请前辈们帮我改正确，十分感谢！

。。。。。 全是错。

import java.awt.BorderLayout;

import java.awt.event.WindowAdapter;

public class SortIt extends JFrame

button.addActionListener(

}

}
public void sortStr(JTextField j1,JTextField j2)
{

ArrayList <Integer> array=new ArrayList <Integer> ();

while (st.hasMoreElements())
{
array.add(Integer.parseInt(st.nextToken()));
}

j2.setText(array.toString());
}
public static void main(String[] args)
{
SortIt si=new SortIt();
si.setVisible(true);
si.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

}

有段时间不用这些了，就当复习了，有问题大家指出来
