Hi Friend,

Try the following code:

import java.util.*;
class  Add3Days{
    public static void main(String[] args) {
    Calendar cal = Calendar.getInstance();
    System.out.println("Current date : " + ( cal.get(Calendar.DATE)) + "/" + (cal.get(Calendar.MONTH) + 1)+ "/"+cal.get(Calendar.YEAR));
    cal.add(Calendar.DATE, 3);
    System.out.println("Date after 3 days: " +  (cal.get(Calendar.DATE))+ "/"+ (cal.get(Calendar.MONTH) + 1) + "/" + cal.get(Calendar.YEAR));
}
}

Thanks
