java判断页面停留时间计算 java判断在某个时间段之内

用于限时循环的活动:

public class TestDate
{
public static void main(String[] args)
{
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = new Date();
String strDate = sdf.format(date);
// 截取当前时间时分
int strDateH = Integer.parseInt(strDate.substring(11, 13));
int strDateM = Integer.parseInt(strDate.substring(14, 16));
String curTime = strDateH+":"+strDateM;
System.out.println(curTime);
String sourceTime ="09:00-23:00";
boolean inTime = isInTime(sourceTime, curTime);
System.out.println(inTime);
}
/**
* 判断某一时间是否在一个区间内
*
* @param sourceTime
* 时间区间,半闭合,如[10:00-20:00)
* @param curTime
* 需要判断的时间 如10:00
* @return
* @throws IllegalArgumentException
*/
