Java TimeUnit toDays()用法及代码示例


TimeUnit类的toDays()方法用于获取自1970年1月1日午夜UTC以来由TimeUnit对象表示的时间(以天数表示)。它等效于DAYS.convert(duration,this)。

用法:

public long toDays(long duration)

参数:此方法接受强制参数持续时间,该持续时间以毫秒为单位。


返回值:此方法将转换后的持续时间返回为“天”。

下面的程序演示了TimeUnit toDays()方法的实现:

示例1:

// Java program to demonstrate 
// toDays() 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 days 
        // using toDays() method 
        System.out.println("Time " + timeInMilliSec 
                           + " milliSeconds in Days = "
                           + time.toDays(timeInMilliSec)); 
    } 
}
输出:
Time 1539585725051 milliSeconds in Days = 17819

示例2:

// Java program to demonstrate 
// toDays() 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 days 
        // using toDays() method 
        System.out.println("Time " + timeInMilliSec 
                           + " milliSeconds in Days = "
                           + time.toDays(timeInMilliSec)); 
    } 
}
输出:
Time 1539585730178 milliSeconds in Days = 17819
