Calendar类中的setTime(Date dt)方法用于设置此Calendar的时间值表示的Calendars时间,并以给定或通过的日期为参数。
用法:
public final void setTime(Date dt))
参数:该方法采用Date类型的一个参数dt表示要设置的给定日期。
返回值:该方法不返回任何值。
以下示例程序旨在说明Calendar类的setTime()方法的用法:
示例1:
// Java code to illustrate
// setTime() method
import java.util.*;
public class Calendar_Demo
extends GregorianCalendar {
public static void main(String[] args)
{
// Creating calendar objects
Calendar calndr1
= (Calendar)Calendar.getInstance();
Calendar calndr2
= (Calendar)Calendar.getInstance();
// Displaying the current date
System.out.println("The Current"
+ " System Date: "
+ calndr1.getTime());
// Setting to a different date
calndr1.set(Calendar.MONTH, 5);
calndr1.set(Calendar.YEAR, 2006);
calndr1.set(Calendar.DAY_OF_WEEK, 15);
Date dt = calndr1.getTime();
// Setting the timevalue
calndr2.setTime(dt);
// Displaying the new date
System.out.println("The modified"
+ " Date:"
+ calndr2.getTime());
}
}
输出:
The Current System Date: Fri Feb 22 07:33:13 UTC 2019 The modified Date:Sun Jun 18 07:33:13 UTC 2006
示例2:
// Java code to illustrate
// setTime() method
import java.util.*;
public class Calendar_Demo
extends GregorianCalendar {
public static void main(String[] args)
{
// Creating calendar objects
Calendar calndr1
= (Calendar)Calendar.getInstance();
Calendar calndr2
= (Calendar)Calendar.getInstance();
// Displaying the current date
System.out.println("The Current"
+ " System Date: "
+ calndr1.getTime());
// Setting to a different date
calndr1.set(Calendar.MONTH, 10);
calndr1.set(Calendar.YEAR, 1995);
calndr1.set(Calendar.DAY_OF_WEEK, 20);
Date dt = calndr1.getTime();
// Setting the timevalue
calndr2.setTime(dt);
// Displaying the new date
System.out.println("The modified"
+ " Date: "
+ calndr2.getTime());
}
}
输出:
The Current System Date: Fri Feb 22 07:33:20 UTC 2019 The modified Date: Fri Nov 24 07:33:20 UTC 1995
