Java Data Type - 如何将ZoneId转换为TimeZone

import java.time.ZoneId;
import java.util.TimeZone;

public class Main {
    public static void main(String[] args) {
      ZoneId defaultZone = TimeZone.getDefault().toZoneId();
      
      TimeZone tz = TimeZone.getTimeZone(defaultZone);
      System.out.println(tz);
    }
}
