Java 中的日历设置时区()方法，带示例
原文:https://www . geesforgeks . org/calendar-settimezone-method-in-Java-with-examples/
Calendar 类中的setTimeZone(Time _ Zone)方法以时区值为参数，修改或设置该 Calendar 所代表的时区。
语法:
public void setTimeZone(TimeZone *time_zone*)
参数:该方法取日期类型的一个参数时区，指的是要设置的给定日期。
返回值:该方法不返回值。
以下程序说明了日历类 setTimeZone()方法的工作: 示例 1:
// Java code to illustrate
// setTime() method
import java.util.*;
public class Calendar_Demo {
public static void main(String[] args)
{
// Creating calendar object
Calendar calndr = Calendar.getInstance();
// Displaying the current time zone
String tz_name = calndr.getTimeZone()
.getDisplayName();
System.out.println("The Current Time"
+ " Zone: " + tz_name);
TimeZone time_zone
= TimeZone.getTimeZone("GMT");
// Modifying the time zone
calndr.setTimeZone(time_zone);
// Displaying the modified zone
System.out.println("Modified Zone: "
+ calndr.getTimeZone()
.getDisplayName());
}
}
Output:
The Current Time Zone: Coordinated Universal Time
Modified Zone: Greenwich Mean Time
例 2:
// Java code to illustrate
// setTimeZone() method
import java.util.*;
public class Calendar_Demo {
public static void main(String[] args)
{
// Creating calendar object
Calendar calndr = Calendar.getInstance();
// Displaying the current time zone
String tz_name = calndr.getTimeZone()
.getDisplayName();
System.out.println("The Current Time"
+ " Zone: " + tz_name);
TimeZone time_zone
= TimeZone.getTimeZone("Pacific/Tahiti");
// Modifying the time zone
calndr.setTimeZone(time_zone);
// Displaying the modified zone
System.out.println("Modified Zone: "
+ calndr.getTimeZone()
.getDisplayName());
}
}
Output:
The Current Time Zone: Coordinated Universal Time
Modified Zone: Tahiti Time
