Q1: java动画 图形失真的问题（例程：时钟程序） 求解决 谢谢了！
点阵的 失真是很正常的了。。。。。。。。换个视网膜的屏试试，可能会好很多。
Q2: 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;
}
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java时钟动画代码，给每一段编号，
5 1
6
4 2
3
然后设计10个长度为7java时钟动画代码的数组,作为每个数字java时钟动画代码的字体
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。
