Calendar類中的setTimeInMillis(long mill_sec)方法用於根據傳遞的long值設置由此Calendar表示的Calendars時間。
用法:
public void setTimeInMillis(long mill_sec)
參數:該方法采用long類型的一個參數mill_sec,表示要設置的給定日期。
返回值:該方法不返回任何值。
以下示例程序旨在說明Calendar類的setTimeInMillis()方法的用法:
示例1:
// Java code to illustrate
// setTimeInMillis() method
import java.util.*;
public class Calendar_Demo {
public static void main(String args[])
{
// Creating calendar object
Calendar calndr = Calendar.getInstance();
// Getting the time in milliseconds
System.out.println("The Current"
+ " Time is: "
+ calndr.getTime());
// Changing time to 2000 milli-second
calndr.setTimeInMillis(2000);
// Displaying the new time
System.out.println("After setting"
+ " Time: "
+ calndr.getTime());
}
}
輸出:
The Current Time is: Fri Feb 22 08:00:54 UTC 2019 After setting Time: Thu Jan 01 00:00:02 UTC 1970
示例2:
// Java code to illustrate
// setTimeInMillis() method
import java.util.*;
public class Calendar_Demo {
public static void main(String args[])
{
// Creating calendar object
Calendar calndr = Calendar.getInstance();
// Getting the time in milliseconds
System.out.println("The Current"
+ " Time is: "
+ calndr.getTime());
// Changing time to 8000 milli-second
calndr.setTimeInMillis(8000);
// Displaying the new time
System.out.println("After setting"
+ " Time: "
+ calndr.getTime());
}
}
輸出:
The Current Time is: Fri Feb 22 08:01:02 UTC 2019 After setting Time: Thu Jan 01 00:00:08 UTC 1970
