LocalTime類的plusNanos()方法用於向此LocalTime添加指定的毫微秒值,並將結果作為LocalTime對象返回。這一瞬間是一成不變的。計算大約在午夜結束。
用法:
public LocalTime plusNanos(long nanosecondsToAdd)
參數:此方法接受單個參數nanosecondsToAdd,該參數是要添加的納秒值,它可以是負值。
返回值:此方法基於此時間返回LocalTime,並添加了納秒。
以下示例程序旨在說明plusNanos()方法:
示例1:
// Java program to demonstrate
// LocalTime.plusNanos() method
import java.time.*;
public class GFG {
public static void main(String[] args)
{
// create a LocalTime object
LocalTime time
= LocalTime.parse("19:34:50.63");
// print LocalTime
System.out.println("LocalTime before add: "
+ time);
// add 34000000 nanoseconds using plusNanos()
LocalTime value = time.plusNanos(34000000);
// print result
System.out.println("LocalTime after add: "
+ value);
}
}
輸出:
LocalTime before add: 19:34:50.630 LocalTime after add: 19:34:50.664
示例2:
// Java program to demonstrate
// LocalTime.plusNanos() method
import java.time.*;
public class GFG {
public static void main(String[] args)
{
// create a LocalTime object
LocalTime time
= LocalTime.parse("01:00:01");
// print LocalTime
System.out.println("LocalTime before add: "
+ time);
// add -971200000 nanoseconds using plusNanos()
LocalTime value = time.plusNanos(-971200000);
// print result
System.out.println("LocalTime after add: "
+ value);
}
}
輸出:
LocalTime before add: 01:00:01 LocalTime after add: 01:00:00.028800
