快速提问,我需要在特定时间段过后(以毫秒为单位)执行某种方法:

然而,由于时间间隔的具体程度,我的程序从未触及过任何一个。
这样做的最佳方式是什么?
答案 0 :(得分:1)
仅当currDate.getTime() == currDate.getTime() + incr01001
时,此类表达式true
才会评估为incr01001 == 0
。出于同样的原因x == x + y
仅在y == 0
。
答案 1 :(得分:1)
仅在特定时间段过后(以毫秒为单位)执行某种方法:
您可以使用Thread.sleep(long milliseconds)
方法来执行此操作。
try{
Thread.sleep(5000);//for 5 seconds
} catch(Exception ex){
System.out.println("Error: "+ex.getMessage());
}
答案 2 :(得分:0)
首先尝试在while块之外获取时间:
Date date = new Date();
while (true)
{
currDate = new Date();
if (currDate.getTime() == date.getTime() + incrTrueBinaryErr)
//do stuff
//etc.
}
这样,while循环不会继续重新分配日期。
如你所说,它可能也有点过于具体,所以对于你的if
块可能:
long timeDifference = date.getTime()+incrTrueBinaryErr-currDate.getTime();
if (Math.abs(timeDifference)<5l)
//do stuff
如果新时间在你想要的5毫秒之内,“做点什么”。
