求Java 编写的数字时钟的七段数码样式显示 求Java 编写的数字时钟的七段数码样式显示 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 LZ说地是七段数码管的数字字体,你去网上找下,有这样的字体网站的。我有一份,要不你给EMAIL我发你吧。 学习了,百度后知道是电梯里的LED那种数字的显示方式。 这里有个控制台版本输出七段 LED 数字:http://topic.csdn.net/u/20080818/21/e77f9240-a491-43da-96b6-18f1be97eda2.html 没有写过 Java 版本的时钟,写过一个 JavaScript 版本的:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>无标题文档 </title> <script type="text/javascript" src="link/led.js"></script><script type="text/javascript">window.onload = function() { var width = 8; var height = 16; var weight = 6; var dark = '#efefef'; var color = '#000000'; var year = new Led({ parent: 'year', count: 4, width: width, height: height, weight: weight, spacing: 2, dark: dark, color: color }); var month = new Led({ parent: 'month', count: 2, width: width, height: height, weight: weight, spacing: 2, dark: dark, color: color }); var day = new Led({ parent: 'day', count: 2, width: width, height: height, weight: weight, spacing: 2, dark: dark, color: color }); var hour = new Led({ parent: 'hour', count: 2, width: width, height: height, weight: weight, spacing: 2, dark: dark, color: color }); var minute = new Led({ parent: 'minute', count: 2, width: width, height: height, weight: weight, spacing: 2, dark: dark, color: color }); var second = new Led({ parent: 'second', count: 2, width: width, height: height, weight: weight, spacing: 2, dark: dark, color: color }); var d = new Date(); var _year = d.getYear(); year.showNumber((_year < 1900 ?

关于java中 子类显式调用父类的构造函数问题,请大家帮忙看看... 关于线程死锁问题望高手解答(下附代码)
