JAVA编程题 甲乙丙三个人放鞭炮，甲3分钟放一个，乙5分钟放一个，丙7分钟放一个，问2小时内可以听到几次鞭
class Listener{
public static void main(String[]args){
int count = 0; //定义一个统计变量
for(int i=1;i=120;i++){
if(i%3==0||i%5==0||i%7==0)
count++;
}
System.out.prinlnt("听到"+count);
}
}
关于java特效烟花
一个脚本 QQ空间不支持
你找个FLASH带JAVA脚本的 然后找出正确地址.
然后在QQ空间的自定义 添加模块 FLASH模块里
把地址复制上点确定 再托大到合适角度 一样有这样的效果
QQ空间代码的网站都有 百度一找一堆!
