请用代码实现:获取当前的日期,并把这个日期转换为指定格式的字符串,如2088-08-08 08:08:08。

public class Test05 {
    public static void main(String[] args) {
       Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.YEAR,1988);//年
        calendar.set(Calendar.MONTH,8);//月
        calendar.set(Calendar.DAY_OF_MONTH,8);//天
        calendar.set(Calendar.HOUR,8);//时
        calendar.set(Calendar.MINUTE,8);//分
        calendar.set(Calendar.SECOND,8);//秒
        int year = calendar.get(Calendar.YEAR);
        int month = calendar.get(Calendar.MONTH);
        int day = calendar.get(Calendar.DAY_OF_MONTH);
        int hours = calendar.get(Calendar.HOUR);
        int minute = calendar.get(Calendar.MINUTE);
        int second = calendar.get(Calendar.SECOND);
        System.out.println(year+"-"+month+"-"+day+" "+hours+":"+minute+":"+second);


    }
}
