​

​

import java.util.Calendar;/*来 自 N o  w  J a v a . c o m - 时  代  Java*/

​

​

public class Main {

​

​

  public static void main(String[] args) {

​

    Calendar now = Calendar.getInstance();

​

​

    System.out.println("Current date : " + (now.get(Calendar.MONTH) + 1)

​

                        + "-"

​

                        + now.get(Calendar.DATE)

​

                        + "-"

​

                        + now.get(Calendar.YEAR));

​

​

​

    //add year to current date using Calendar.add method

​

    now.add(Calendar.YEAR,1);

​

   /*from nowjava.com - 时  代  Java*/

​

    System.out.println("date after one year : " + (now.get(Calendar.MONTH) + 1)

​

                        + "-"

​

                        + now.get(Calendar.DATE)

​

                        + "-"

​

                        + now.get(Calendar.YEAR));

​

​

    //subtract year from current date

​

    now =Calendar.getInstance();

​

    now.add(Calendar.YEAR,-100);
