Source not found error when split and covert to double a value read from text file

I have a problem when parsing a string to double after read from a text file. This is my .txt file:

5 2 0 1 166.47234 0 2 170.18475 0 3 174.55453 0 4 153.28670 1 2 145.12186 1 3 144.42723 1 4 170.98466 2 3 176.58110 2 4 162.99632 3 4 168.48360 

In my code, the first line I read, just takes n=5 and m=2. From the second line to the end, I just use the first and the second value as index of a matrix, and the third value is a double, which I want to write in the position of the array given by the first and the second value.

When I read a line, I parse to integer the first two values, and the third one to double.

the problem I am having is that when I split the line with a space as separator (" "), I can get the first and the second value correctly, but I am getting an error with the third one when I try to convert it from String to double. Here is the code:

 static File file_ = new File("C:\\Users\\dlozanoe\\Desktop\\Personal\\Universidad\\2o Semestre\\Tendencias en Inteligencia Artificial\\Tema 3\\Datos.txt"); static int n_localizaciones = 0; static int m = 0; static int contador = 0; static int fila = 0; static int columna = 0; static double enlace = 0; double mejorValorFuncionObjetivo; static double matriz[][]; static String split[]; static boolean seleccion[]; public static void main(String[] args) throws IOException { LeerMatrizArchivo(); for (int i = 0; i < n_localizaciones; i++) { for (int j = 0; j<n_localizaciones; j++) { System.out.print(matriz[i][j] + "\t"); } System.out.println(); } } private static void LeerMatrizArchivo() throws IOException { BufferedReader in = new BufferedReader(new FileReader(file_)); try { String line = in.readLine(); split = line.split(" "); n_localizaciones = Integer.parseInt(split[0]); m = Integer.parseInt(split[1]); matriz = new double [n_localizaciones][n_localizaciones]; line = in.readLine(); while (line != null) { split = line.split(" "); fila = Integer.parseInt(split[0]); columna = Integer.parseInt(split[1]); double enlace = Double.parseDouble(split[2]); matriz[fila][columna] = enlace; matriz[columna][fila] = enlace; line = in.readLine(); } } catch (FileNotFoundException ex){ } finally { in.close(); } } 

In this line:

double enlace = Double.parseDouble(split[2]); 

I am getting the error "Source not found", and I cannot understand why. When I access to this position of the split, it has value inside. Also, in this same line, if I write:

double enlace = Double.parseDouble(split[1]); 

instead of split[2], the program runs with no errors. I think there is something wrong in this split line, but I cannot see what.

Maybe someone can help me because I am not able to see what is wrong here..

Thank you so much.
