The default Scanner<\/code> delimiter is a space. So, one of your next()<\/code> calls is consuming the last name as well as the score (“Potter,72” for example). Hence, the nextInt()<\/code> call is failing.<\/p>\n

Also, you seem to be trying to read four values when you have only two (considering the Scanner<\/code> is treating the last name and score as one). Select either a space or a comma as your delimiter. If you choose to have comma-separated values then use Scanner#useDelimiter(\",\")<\/code> as well.<\/p>\n

Harry,Potter,72\nRon,Weasley,68\n<\/code><\/pre>\n
Considering the file format as above (csv) you can use the code below.<\/p>\n
Scanner input = new Scanner(myFile).useDelimiter(\",\");\n\nwhile (input.hasNextLine()) {\n    String[] line = input.nextLine().split(\",\");\n    String firstName = line[0];\n    String lastName = line[1];\n    int score = Integer.parseInt(line[2]);\n    System.out.println(firstName + \" \" + lastName + \" \" + score);\n}\n<\/code><\/pre>\n<\/p><\/div>\n
