Java Data Type - 如何将TimeZone转换为ZoneId

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

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