猜数字游戏代码

仔细看看。。。

import javax.swing.*;
import javax.swing.text.*;
import java.awt.event.*;
import java.awt.*;

public class NumberInputer extends JTextField implements KeyListener, MouseWheelListener{
double stepSize = 1;
Toolkit toolkit = Toolkit.getDefaultToolkit();

public NumberInputer() {
Keymap keymap = getKeymap();
keymap.addActionForKeyStroke(KeyStroke.getKeyStroke(KeyEvent.VK_UP, 0),
new AbstractAction() {
public void actionPerformed(ActionEvent e) {
nextStep();
}
});
keymap.addActionForKeyStroke(KeyStroke
.getKeyStroke(KeyEvent.VK_DOWN, 0), new AbstractAction() {
public void actionPerformed(ActionEvent e) {
previousStep();
}
});
addKeyListener(this);
addMouseWheelListener(this);
setHorizontalAlignment(RIGHT);
}
