我将

Collection.min与自定义比较器一起使用,该比较器根据与当前时间的距离“命令”日期.

final long now = System.currentTimeMillis();

// Create a sample list of dates

List dates = new ArrayList();

Random r = new Random();

for (int i = 0; i < 10; i++)

dates.add(new Date(now + r.nextInt(10000)-5000));

// Get date closest to "now"

Date closest = Collections.min(dates, new Comparator() {

public int compare(Date d1, Date d2) {

long diff1 = Math.abs(d1.getTime() - now);

long diff2 = Math.abs(d2.getTime() - now);

return Long.compare(diff1, diff2);

}

});
