求java七段数字时钟的源代码其实这个很有趣 。自己写很有意思
先画每个数字.....
每个数字图样分7段，给每一段编号，
51
6
42
3
然后设计10个长度为7的数组,作为每个数字的字体
boolean[][] font={
{true, true,true,true,true,true,false},//数字0的字样控制开关
{false, true,true,false,false,false,false},//数字1的字样控制开关
//等等等等
{true, true,true,true,false,true,true},//数字9的字样控制开关
}
或者，熟练的就用一个byte数组就够了
byte[] font={
0x3F, ////数字0的字样控制开关
0x06,//数字1的字样控制开关
//等等
0x6F//数字9的字样控制开关
}
然后画几个黑段拼出一个数字 ， 对应数组显示，用6个数字实例拼出最终效果，
这是模拟真机的写法.
如果要简单，直接拿0-9共10张图片对应数值就可以了 。
JAVA时钟代码解释lz这个代码有什么看不懂的 如果这个代码看不懂的话 建议你从基础的开始学习吧
首先可以看到extends JFrame implements ActionListener 关于ActionListener 接口和JFrame 类lz有必要去看看 加入api慢慢研究下吧
int x,y,x0,y0,r,h,olds_x,olds_y,oldm_x,oldm_y,oldh_x,oldh_y,ss,mm,hh,old_m,old_h,ang;
这些东西我也看不懂 因为你的代码不完整
final double RAD=Math.PI/180; 这个应该是算一个弧度吧
super("made by mcj and wdh"); 这句无意义 是父类的代码
setDefaultCloseOperation(3);这个方法是什么？？代码不完整
setSize(300,300);设置窗体大小
setBackground(Color.white);设置背景色
setLocation(300,150); 定位
setResizable(false);不调整大小
setVisible(true);可见
后面的就没有代码了
用 java 写一个clock的类，100毫秒的时钟 求代码 。。越简单越好 。。最好有注释这里有一个时钟java时钟转动代码的类java时钟转动代码 ， java时钟转动代码你看一下吧，不明白你java时钟转动代码的100毫秒的时钟 是什么意思 。
