Question

I need this in Java, please!

The ISO 8601 Standard date format for Information Interchange indicates that a date be written as such: yyyy-MM-dd (eg. 2012-07-02, 1999-12-05, 1998 -01-27 ) where yyyy represents the four digit year MM represents a two digit numerical month dd represents a two digit numerical day Chinese date format is specified as: yyyy-M-d Macedonean date format is specified as: d.M.yyyy where yyyy represents the four digit year M represents a one or two digit numerical month, as appropriate d represents a one or two digit numerical day, as appropriate

You are to write a program which converts dates from Chinese and Macedonean formats to ISO format. The program will : * ask the user which format they will be entering (C - Chinese or M - Macedonean) * accept the user input, determining which conversion to perform * output the ISO version of the date that was input * Your program should delegate at least one action to a function (for example single digit days will need to be converted to double digits, single digit months will need to be converted to double digits)

import java.util.Scanner;

public class Demo{
   public static void main(String args[]) {
       Scanner s=new Scanner(System.in);
       String date="";
       System.out.println("Enter format in which date will be entering (C - Chinese or M - Macedonean) ");
      
       char ch=s.next().charAt(0);
       System.out.println("Enter date");
       String d=s.next();
       if(ch=='C') {
           String m[]=d.split("-");
           date+=m[0]+"-";
           if(m[1].length()==1)
               date+="0"+m[1]+"-";
           else
               date+=m[1]+"-";
           if(m[2].length()==1)
               date+="0"+m[2];
           else
               date+=m[2];
       }
       else {
           String m[]=d.split("/.");
           date+=m[2];
           if(m[1].length()==1)
               date+="0"+m[1]+"-";
           else
               date+=m[1]+"-";
           if(m[0].length()==1)
               date+="0"+m[0];
           else
               date+=m[0];
          
       }
       System.out.println("Date in ISO format "+date);
   }
