Q3: 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，

5 1

6

4 2

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。

Q4: 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
