[Q#23307324][A#23307365] How do I add 2 weeks to a Date in java?

https://stackoverflow.com/q/23307324

I am getting a Date from the object at the point of instantiation, and for the sake of outputting I need to add 2 weeks to that date. I am wondering how I would go about adding to it and also whether or not my syntax is correct currently. Current Java: Is this syntax correct? Also, I want to make a getter that returns an estimated shipping date, which is 14 days after the date of order, I'm not sure how to add and subtract from the current date.

Use Calendar and set the current time then user the add method of the calendar try this:

APIzation

int noOfDays = 14; //i.e two weeks
Calendar calendar = Calendar.getInstance();
calendar.setTime(dateOfOrder);            
calendar.add(Calendar.DAY_OF_YEAR, noOfDays);
Date date = calendar.getTime();

package com.stackoverflow.api;

import java.util.Calendar;
import java.util.Date;

public class Human23307365 {

  public static Date addTwoWeeksToDate(Date dateOfOrder) {
    int noOfDays = 14; //i.e two weeks
    Calendar calendar = Calendar.getInstance();
    calendar.setTime(dateOfOrder);
    calendar.add(Calendar.DAY_OF_YEAR, noOfDays);
    return calendar.getTime();
  }
}
