Java 中的日历设置时间()方法，示例
原文:https://www . geesforgeks . org/calendar-settime-method-in-Java-with-examples/
Calendar 类中的设置时间(日期 dt ) 方法用于设置由该 Calendar 的时间值表示的 Calendar 时间，给定或过去的日期作为参数。
语法:
public final void setTime(Date *dt*))
参数:该方法取日期类型的一个参数 dt ，指的是要设置的给定日期。
返回值:该方法不返回值。
下面的程序说明了日历类的 setTime()方法的工作: 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());
}
}
Output:
The Current System Date: Fri Feb 22 07:33:13 UTC 2019
The modified Date:Sun Jun 18 07:33:13 UTC 2006
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());
}
}
Output:
The Current System Date: Fri Feb 22 07:33:20 UTC 2019
The modified Date: Fri Nov 24 07:33:20 UTC 1995
