Q1: 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

4 2

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。

Q3: JAVA用SWT写时钟代码

#include time.h

#include stdio.h

#include stdlib.h

#define BUF_SIZE 80

int main()

{

time_t t;

struct tm *tm;

char s[BUF_SIZE];

if(time(t) == ((time_t)-1)) return 1;

tm = localtime(t);

if(!tm) return 1;

strftime(s, sizeof(s), ":%H:%M:%S", tm);

printf("%s\n", s);

system("pause");

return 0;

}
