如何在Java中使用不同的TimeZone获取当前时间？

import java.util.Calendar;
import java.util.TimeZone;

public class Main {
    public static void main(String[] args) {
        String timeZone = "Asia/Shanghai"; // 您可以在这里设置所需的时区
        Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone(timeZone));
        int hour = calendar.get(Calendar.HOUR_OF_DAY);
        int minute = calendar.get(Calendar.MINUTE);
        int second = calendar.get(Calendar.SECOND);

        System.out.printf("当前 %s 时区的时间是: %02d:%02d:%02d\n", timeZone, hour, minute, second);
    }
}
