java倒计时代码并转换,java 倒计时器

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

Q1: 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");

}

Q2: 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
