Java中的日历 setTimeZone() 方法及示例
Calendar 类中的setTimeZone(TimeZone time_zone)方法将 Time Zone 值作为参数,修改或设置此 Calendar 表示的时区。
句法:
public void setTimeZone(TimeZone time_zone)
参数:该方法采用一个日期类型的参数time_zone ,并引用要设置的给定日期。
返回值:该方法不返回任何值。
下面的程序说明了 Calendar 类的 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());
}
}
输出:
The Current Time Zone: Coordinated Universal Time
Modified Zone: Greenwich Mean Time
示例 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());
}
}
输出:
The Current Time Zone: Coordinated Universal Time
Modified Zone: Tahiti Time
