Java TimeUnit toMicros()方法及示例

TimeUnit类 的 toMicros() 方法用于获取TimeUnit对象所代表的时间，即自1970年1月1日UTC午夜起的微秒数。

语法

public long toMicros(long duration)

参数： 该方法接受一个强制性参数 duration ，它是以毫秒为单位的持续时间。

返回值： 该方法返回 转换后的持续时间 为微秒。

以下程序说明了TimeUnit toMicros()方法的实现。

程序 1 :

// Java program to demonstrate// toMicros() method of TimeUnit Class import java.util.concurrent.*;import java.util.Date; class GFG {    public static void main(String args[])    {        // Get current time in milliseconds        long timeInMilliSec = new Date().getTime();         // Create a TimeUnit object        TimeUnit time = TimeUnit.MILLISECONDS;         // Convert milliseconds to MicroSeconds        // using toMicros() method        System.out.println("Time " + timeInMilliSec                           + " milliSeconds in MicroSeconds = "                           + time.toMicros(timeInMilliSec));    }}

输出

Time 1539585538596 milliSeconds in MicroSeconds = 1539585538596000

程序2 。

// Java program to demonstrate// toMicros() method of TimeUnit Class import java.util.concurrent.*;import java.util.Calendar; class GFG {    public static void main(String args[])    {        // Get current time in milliseconds        long timeInMilliSec = Calendar                                  .getInstance()                                  .getTimeInMillis();         // Create a TimeUnit object        TimeUnit time = TimeUnit.MILLISECONDS;         // Convert milliseconds to MicroSeconds        // using toMicros() method        System.out.println("Time " + timeInMilliSec                           + " milliSeconds in MicroSeconds = "                           + time.toMicros(timeInMilliSec));    }}

输出

Time 1539585540908 milliSeconds in MicroSeconds = 1539585540908000
