搞IT还是该会一点java

代码：

import java.io.*;
import java.util.*;

public class Main
{
    public static void main(String[] args)
    {
        Scanner cin = new Scanner(System.in);
        int t = cin.nextInt();
        while ( t -- > 0 )
        {
            int d = cin.nextInt();
            Calendar calendar = Calendar.getInstance();

            calendar.add(Calendar.DAY_OF_MONTH, d+1);
            int year = calendar.get( Calendar.YEAR );
            int month = 1 + calendar.get( Calendar.MONTH );
            int day = calendar.get( Calendar.DAY_OF_MONTH );
            
            System.out.print(year+"/");
            if ( month < 10 )
                System.out.print("0");
            System.out.print(month+"/");
            if ( day < 10 )
                System.out.print("0");
            System.out.print(day+" ");

            Calendar calendar2 = Calendar.getInstance();

            calendar2.add(Calendar.DAY_OF_MONTH, 1-d);
            year = calendar2.get( Calendar.YEAR );
            month = 1+ calendar2.get( Calendar.MONTH );
            day = calendar2.get( Calendar.DAY_OF_MONTH );
            
            System.out.print(year+"/");
            if ( month < 10 )
                System.out.print("0");
            System.out.print(month+"/");
            if ( day < 10 )
                System.out.print("0");
            System.out.println(day);
        }
    }
}

C/C++代码：

	}
}
