可以使用tick()Java中Clock類中的方法在所需的時間范圍內舍入基本時鐘的瞬間。此方法需要兩個參數，即基本時鐘和滴答的持續時間。同樣，返回在所需持續時間內四舍五入的基本時鐘時刻。

演示此的程序如下所示-

示例import?java.time.*;

public?class?Main?{

public?static?void?main(String[]?args)?{

Clock?bClock?=?Clock.systemDefaultZone();

Instant?i?=?bClock.instant();

System.out.println("The?Instant?of?the?base?clock?is:?"?+?i);

Clock?c1?=?Clock.tick(bClock,?Duration.ofSeconds(45));

System.out.println("Instant?of?the?first?clock?with?duration?45?seconds?is:?"?+?c1.instant());

Clock?c2?=?Clock.tick(bClock,?Duration.ofHours(45));

System.out.println("Instant?of?the?first?clock?with?duration?45?hours?is:?"?+?c2.instant());

Clock?c3?=?Clock.tick(bClock,?Duration.ofDays(45));

System.out.println("Instant?of?the?first?clock?with?duration?45?days?is:?"?+?c3.instant());

}

}

輸出結果The?Instant?of?the?base?clock?is:?2019-02-06T12:26:22.488Z

Instant?of?the?first?clock?with?duration?45?seconds?is:?2019-02-06T12:26:15Z

Instant?of?the?first?clock?with?duration?45?hours?is:?2019-02-05T12:00:00Z

Instant?of?the?first?clock?with?duration?45?days?is:?2019-01-14T00:00:00Z

現在讓我們了解上面的程序。

使用方法將基本時鐘的時刻四舍五入至所需的持續時間tick()。然后使用instant()方法顯示。演示這的代碼片段如下-Clock?bClock?=?Clock.systemDefaultZone();

Instant?i?=?bClock.instant();

System.out.println("The?Instant?of?the?base?clock?is:?"?+?i);

Clock?c1?=?Clock.tick(bClock,?Duration.ofSeconds(45));

System.out.println("Instant?of?the?first?clock?with?duration?45?seconds?is:?"?+?c1.instant());

Clock?c2?=?Clock.tick(bClock,?Duration.ofHours(45));

System.out.println("Instant?of?the?first?clock?with?duration?45?hours?is:?"?+?c2.instant());

Clock?c3?=?Clock.tick(bClock,?Duration.ofDays(45));

System.out.println("Instant?of?the?first?clock?with?duration?45?days?is:?"?+?c3.instant());
