    Default Scanner/FileReader help

    This particular part of my project requires me to find an employee ID in an array, then read in the next line as a number of hours. How I'm doing all this doesn't really matter, but when I run the program I get "Exception in thread "main" java.util.InputMismatchException
    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 TestEmp.main(TestEmp.java:107)"

    ...which makes me think that I'm reading through the file wrong.

    	Scanner newfile = new Scanner(new FileReader("Hourly.dat"));
    int search;
    int index;
    while(newfile.hasNext())
    {
      search = newfile.nextInt();
      index = bsearch(empArray, 0, i, search);
      if(empArray[index].getType()== 'H'){
      ((Hourly)empArray[index]).setHours(newfile.nextFloat());
      newfile.nextLine();
      }
    }
    newfile.close();

    and the file I'm reading:
    3212 92.50
    3333 100.00
    3999 85.00
    3112 80.00
    3444 81.00
    3987 90.00
    3564 80.00
    3215 80.00
    3665 87.00
    3985 88.00

    Any ideas to fix this problem would be appreciated.

    Default Re: Scanner/FileReader help

    That means you're reading in the wrong type of data for the command you're using.

    For instance, reading in "abcd" and saying

    int n = that value.

    Also, I noticed there's a double variable on the second half of each line. I think it's trying to read that in too.
