关于JAVA里的倒计时代码
我试了一下没有错呀!

我还有一个：
script LANGUAGE="JavaScript"
!--你可以将新年改为其它的节日--
var urodz= new Date("January 29,2006");
var s="新年";
var now = new Date();
var ile = urodz.getTime() - now.getTime();
var dni = Math.floor(ile / (1000 * 60 * 60 * 24));
if (dni 1)
document.write("今天离"+s+"还有"+dni +"天")
else if (dni == 1)
document.write("只有2天啦！")
else if (dni == 0)
document.write("只有1天啦！")
else
document.write("好象已经过了哦！");
/script
java 就一个100 的倒计时代码 代码简单点
public static void main(String[] args) {
for (int i = 100 ; i = 0 ; i --) {
System.out.println(i);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
System.out.println("结束");
}
怎么编写一个倒计时的java的程序？求具体步骤！
基于控制台的话很简单的，我跟你说一下大体思路吧，二话不说先来个for循环，然后输出倒计时的数字，程序睡一秒，在输出倒计时数字，如此循环，简单吧，下面看程序：
public static void main(String[] args) {
for(int i=10;i0;i--){
System.out.print(i+" ");
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
System.err.print("爆炸");
}
其他基于网页的还是基于用户界面都可以使用这个思路的
用java编写一个倒计时器代码。
import java.awt.BorderLayout;import java.awt.Container;import java.awt.Font;import java.awt.GridLayout;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JOptionPane;import javax.swing.JPanel;import javax.swing.JTextField;public class TimerDemo extends JFrame implements ActionListener { private static final long serialVersionUID = 201306211111L; private JTextField screen = new JTextField("0"); private JButton start = new JButton("开始"); private JButton reset = new JButton("重置"); private JPanel panel = new JPanel(); private boolean isRunning; private int time; private int timeBetween; public TimerDemo(int timeBetween) { super("计时器"); this.timeBetween = timeBetween; try { init(); } catch (Exception e) { e.printStackTrace(); } } public TimerDemo() { super("计时器"); this.timeBetween = 100; try { init(); } catch (Exception e) { e.printStackTrace(); } } private void init() { panel.setLayout(new GridLayout()); panel.add(start); panel.add(reset); start.addActionListener(this); reset.addActionListener(this); screen.setFont(new Font("幼圆", Font.BOLD, 60)); screen.setHorizontalAlignment(JTextField.CENTER); screen.setEditable(false); Container c = getContentPane(); c.setLayout(new BorderLayout()); c.add(panel, BorderLayout.SOUTH); c.add(screen, BorderLayout.CENTER); this.setSize(200, 150); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setResizable(false); this.setLocationRelativeTo(null); this.setVisible(true); } public static void main(String[] args) { new TimerDemo(1);// 设定 1ms/次 // new TimerDemo(); } @Override public void actionPerformed(ActionEvent e) { if (e.getSource() == start) { if (start.getText().equals("开始")) { start.setText("暂停"); isRunning = true; } else if (start.getText().equals("暂停")) { start.setText("开始"); isRunning = false; } } if (e.getSource() == reset) { start.setText("开始"); screen.setText("0"); isRunning = false; time = 0; } new Thread(new TimeZone()).start(); } class TimeZone implements Runnable { @Override public void run() { while (isRunning) { time++; if (time = Integer.MAX_VALUE) { screen.setText("ERROR"); JOptionPane.showMessageDialog(null, "ERROR"); isRunning = false; } screen.setText(String.valueOf(time)); try { Thread.sleep(timeBetween); } catch (Exception e) { e.printStackTrace(); } } } }}
java中30秒倒计时（转换成string返回到Label控件的text）
