怎么获取当前时间 要求年月日时分秒 用java代码实现

要获取当前时间，并以年月日时分秒的格式显示，可以使用Java中的Date类和SimpleDateFormat类。以下是一个示例代码：

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

public class GetCurrentTime {
    public static void main(String[] args) {
        Date date = new Date();
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String currentTime = dateFormat.format(date);
        System.out.println(currentTime);
    }
}

通过以上代码，你可以获取当前的年月日时分秒，并以字符串的形式显示出来。例如，输出可能是：2021-08-20 15:30:45。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
