import java.util.Calendar;
        Calendar cal = Calendar.getInstance();
        int day = cal.get(Calendar.DATE);
        int month = cal.get(Calendar.MONTH) + 1;
        int year = cal.get(Calendar.YEAR);
        String Month2 = Integer.toString(month);
        String Year2 = Integer.toString(year);
        String Day2 = Integer.toString(day);
        vars.put("Month",Month2);
        vars.put("Year",Year2);
        vars.put("Day",Day2);

import java.util.Calendar;

public class date2 {
    public static void main(String[] args) {
        Calendar calendar = Calendar.getInstance();//获取日历
        calendar.add(Calendar.DATE, 180);
        Date d = calendar.getTime();//把日历转换为Date
        System.out.println(d);
int month = calendar.get(Calendar.MONTH) + 1;
        int year = calendar.get(Calendar.YEAR);
        int day = calendar.get(Calendar.DATE);
        System.out.println(month);
