写了一个Swing版本的，楼主的Applet应该很容易能写了：
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
class InputPanel extends JPanel {
private JTextField inputText;
private JTextField outputText;
InputPanel() {
TextPanel panel = new TextPanel();
add(panel);
}
private class TextPanel extends JPanel {
int num; //The input numbers' total number
int data[];
TextPanel() {
setLayout(new BorderLayout());
inputText = new JTextField(20);
outputText = new JTextField(20);
add(inputText, BorderLayout.NORTH);
add(outputText, BorderLayout.SOUTH);
inputText.addActionListener(new
ActionListener() {
public void actionPerformed(ActionEvent e) {
String input = inputText.getText();
//Suppose we use " " to divide the input
StringTokenizer token = new StringTokenizer(input, " ");
int length = token.countTokens();
data = new int[length];
for(int i = 0; i < length; i++)
data[i] = Integer.parseInt(token.nextToken());
sort(data, length);
//Let's make the output string
StringBuffer output = new StringBuffer();
for(int j = 0; j < length; j++)
{
output.append(data[j]);
output.append(" ");
}
outputText.setText(output.toString());
}
});
}
private void sort(int[] a, int len) {
int i, j, temp;
for(i = 0; i < len-1; i++)
for(j = i+1; j < len; j++)
if(a[i] > a[j]) {
temp = a[i];
a[i] = a[j];
a[j] = temp;
}
}
}
}
class InputFrame extends JFrame {
InputFrame() {
setTitle("Input Test");
setSize(300, 200);
getContentPane().add(new InputPanel());
}
}
public class Test {
public static void main(String[] args) {
InputFrame frame = new InputFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.show();
}
}
