Java MisMatchException while using scanner, but why? -

hi trying read input.txt file using scanner, keep getting input mismatch exception , unsure why. file reading in formatted this: first single number identify array size. next line list of integers delimited commas. have fails on first integer being read in:

     file inputfile = new file("input.txt");      scanner scan = new scanner(inputfile);      int arraysize = scan.nextint();      scan.nextline();      int[] array = new int[arraysize];      (int = 0; < arraysize; i++) {          array[i] = scan.nextint();      } 

i think need in there catch commas after each int. maybe scan.next(",")? failing before first comma.

thanks in advance!

edit: input file example:

5 -1, -2, -3 , -4, -5 

file inputfile = new file("c:\\file.txt");     scanner scan = new scanner(inputfile);     string size = scan.nextline(); // read size     string aux = scan.nextline();      aux = aux.replaceall("\\s",""); // remove whitespaces better integer.parseint(string)     string[] parts = aux.split(",");      system.out.println("size "+size);     (int = 0; < parts.length; i++) {         system.out.println(parts[i]);     }     scan.close(); 

then can convert strings integers.
