Java Data Type - 如何在使用简单的日期格式转换时保留毫秒

import java.text.SimpleDateFormat;
import java.util.Date;

public class Main {
  public static void main(String[] args) throws Exception {
    long yourmilliseconds = 1119193123;
    SimpleDateFormat sdf = new SimpleDateFormat("MMM dd,yyyy HH:mm:ss.SSS");

    Date resultdate = new Date(yourmilliseconds);
    System.out.println(sdf.format(resultdate));
  }
}
