java取得耗时时间

final long startTime = System.currentTimeMillis();

Thread.currentThread().sleep(10000);

final long endTime = System.currentTimeMillis();

final long time = endTime - startTime;

System.out.println(time);

final long diffSeconds = time / 1000 % 60;

final long diffMinutes = time / (60 * 1000) % 60;

final long diffHours = time / (60 * 60 * 1000);

System.out.println(diffSeconds);

System.out.println(diffMinutes);

System.out.println(diffHours);
