修改现有日期和结果将采用与java相同的格式

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

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

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

public class DateExample {
    public static void main(String[] args) {
        Date date = new Date();
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(date);
        calendar.add(Calendar.DAY_OF_MONTH, 1);
        Date modifiedDate = calendar.getTime();
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        String formattedDate = sdf.format(modifiedDate);
        System.out.println("Modified Date: " + formattedDate);
    }
}
