java判断时间是否在区间 java判断时间间隔

public static void main(String[] args) throws InterruptedException {
		Date timestrat = new Date();
		System.out.println(timestrat);
		
		//睡眠5秒
		Thread.sleep(5*1000);

		Date timeend = new Date();
		System.out.println(timeend);
		
		//单位是毫秒
        long miao = (timeend.getTime() - timestrat.getTime())/1000;
        System.out.println(miao);
