"Ausnahme im Thread" main "java.util.InputMismatchException"

Question

Wie kann ich die Ausgabe dieses Programms anzeigen? Wenn ich es starte, wird es einen InputMismatchException werfen.

Hier ist der gesamte Code:

import java.util.HashMap; 
import java.util.Scanner; 

public class Try { 

    static HashMap< String, String> codeMap = new HashMap< String, String>(); 
    static HashMap< String, String> ref = new HashMap< String, String>(); 

    static void initMap() { 
     codeMap.put("A", ".-"); 
     codeMap.put("B", "-..."); 
     codeMap.put("C", "-.-."); 
     codeMap.put("D", "-.."); 
     codeMap.put("E", "."); 
     codeMap.put("F", "..-."); 
     codeMap.put("G", "--."); 
     codeMap.put("H", "...."); 
     codeMap.put("I", ".."); 
     codeMap.put("J", ".---"); 
     codeMap.put("K", "-.-"); 
     codeMap.put("L", ".-.."); 
     codeMap.put("M", "--"); 
     codeMap.put("N", "-."); 
     codeMap.put("O", "---"); 
     codeMap.put("P", ".--."); 
     codeMap.put("Q", "--.-"); 
     codeMap.put("R", ".-."); 
     codeMap.put("S", "..."); 
     codeMap.put("T", "-"); 
     codeMap.put("U", "..-");

     codeMap.put(".", "---."); 
     codeMap.put(",", ".-.-"); 
     codeMap.put("?", "----");

    } 

    public static void main(String[] args) { 
     { 
      Scanner in = new Scanner(System.in); 
      System.out.println("Enter Code: "); 
      initMap(); 
      int N = in.nextInt(); 
      for (int i = 1; i <= N; i++) { 
       StringBuffer encry = new StringBuffer(in.next()); 
       StringBuffer inter = new StringBuffer(); 
       StringBuffer num = new StringBuffer(); 

       StringBuffer org = new StringBuffer(); 
       String tmp = new String(encry); 
       for(int j = 0; j < tmp.length(); j++) { 
        inter.append(codeMap.get(tmp.substring(j, j+1))); 
        num.append(codeMap.get(tmp.substring(j, j+1)).length());  
       } 
       num = num.reverse(); 
       int index = 0; 
       for(int j = 0; j < num.length(); j++) { 
        int t1 = Integer.valueOf(num.substring(j, j+1)); 
        StringBuffer con = new StringBuffer(); 
        for(int k = index; k < index+t1;k++) { 
         con.append(inter.substring(k, k+1)); 
        } 
        org.append(ref.get(new String(con))); 
        index += t1; 
       } 
       System.out.printf("%d: %s\n",i,org); 
      } 
     } 
    } 
}

den gesamten Code in einem Try-Block beilegen und den Stack-Trace in dem catch-Block drucken und sieht, auf der Linie dort Fehler sind und entsprechend handeln.
