Java JDBC - 如何将时间戳转换为Date或DateTime对象

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

public class Main {

    public static void main(String[] args) {
        Timestamp timestamp = new Timestamp(System.currentTimeMillis());
        Date date = new Date(timestamp.getTime());

        // S is the millisecond
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy' 'HH:mm:ss:S");

        System.out.println(simpleDateFormat.format(timestamp));
        System.out.println(simpleDateFormat.format(date));
    }
}
