[olga nekrasov]

hello
I have a problem with my code...
here's the complete lines of errors:

Exception in thread "main" java.util.NoSuchElementException
	at java.util.Scanner.throwFor(Unknown Source)
	at java.util.Scanner.next(Unknown Source)
	at java.util.Scanner.nextInt(Unknown Source)
	at java.util.Scanner.nextInt(Unknown Source)
	at hakbaz.Short.reader(Short.java:45)
	at hakbaz.Main.main(Main.java:11)

may be some one know what it means or what can I do to fix it..

		File file = new File("data.TXT");
	    FileInputStream fis = null;

	    try {
	      fis = new FileInputStream(file);
	      bis = new BufferedInputStream(fis);
	      dis = new DataInputStream(bis);
	      str = dis.readLine();
	      sc = new Scanner(str);
	      n=sc.nextInt();
	      str = dis.readLine();

	      t=sc.nextInt();
	      dis.readLine();
	      i=0;
	      int col=(2*x)+3;
	      road = new int[n][col];
	      while (dis.available() != 0) {
	    	str = dis.readLine();
	        sc = new Scanner(str);
	        for (int j=0; j<col; j++)
	        	road[i][j]=sc.nextInt();
	        i++;
	      }

Try System.in for your Scanner, you have it streaming from a string.
