Yesterday Today Tomorrow java acquisition date

 

 I just finished writing the code, it was expelled from the ........

 

 Give it the code for later use:

package mydemo;

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

public class ThreeDay {
    public static void main(String[] args) {
        getToday ();
        getYesterday();
        getTomorrow();
    }

    /**
     * Get today's date
     */
    public static void getToday() {
        //SimpleDateFormat smdate = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
        SimpleDateFormat smdate = new SimpleDateFormat("yyyy年MM月dd日 HH:mm:ss");
        String date = smdate.format(new Date());
        System.out.println(date);
    }

    /**
     * Get yesterday's date
     */
    public static void getYesterday() {
        SimpleDateFormat smdate = new SimpleDateFormat("yyyy年MM月dd日 HH:mm:ss");
        Calendar calendar = new GregorianCalendar();
        calendar.setTime(new Date());
        calendar.add(calendar.DATE, -1);
        String date = smdate.format(calendar.getTime());
        System.out.println(date);
    }

    /**
     * Get tomorrow's date
     */
    public static void getTomorrow() {
        SimpleDateFormat smdate = new SimpleDateFormat("yyyy年MM月dd日 HH:mm:ss");
        Calendar calendar = new GregorianCalendar();
        calendar.setTime(new Date());
        calendar.add(calendar.DATE, 1);
        String date = smdate.format(calendar.getTime());
        System.out.println(date);
    }

}

 

result:
