私はこのサイトを初めて使用し、Java の学習を始めたばかりです。GregorianCalendar に数日追加しようとしていますが、うまくいきません。ここで... (上部のチャンクは無視してください)、面倒なのは下部に日付を追加することです。
/*
* Author:Matt M
* Date:8.12.13
* Discription: When the user inputs the deadline, and the difficulity of the project,
* the program gives the date he should start working on it
*/
import java.util.*;
public class DeadlinePlanner{
public static void main(String[] args)
{
//take information and restart questions if information is wrong
int month = 0, day = 0 ;
do
{
do
{
System.out.println("Input the month please");
month = (new Scanner(System.in).nextInt() - 1);
System.out.println("Input the day please");
day = (new Scanner(System.in).nextInt());
}
while (!(month <= 12) || !(month >= 0));
}
while (!(day <= 31) || !(month >= 0));
//Make new calender and initialize it
GregorianCalendar setup = new GregorianCalendar();
setup.set(2013, month, day);
System.out.println("The deadline is "+ setup.getTime());
//switch statement to give starting date
System.out.println("Is the project hard or easy?");
Scanner difficulity = new Scanner(System.in);
switch (difficulity.nextLine())
{
case "easy":
setup.add(day, -1);
System.out.print("The date you should start workinng on is ");
System.out.println(setup.getTime());
break;
case "hard":
setup.add(day, -10);
System.out.print("The date you should start workinng on is ");
System.out.println(setup.getTime());
break;
default:
System.out.println("Your answers to the questions are incorrect");
