    replied to Trouble parsing int while reading a file
    in Java
    Thank you all for the help.

    I had tried:

    Code:
    sPop = Integer.parseInt(input.substring(32,40).trim()); // breaks here
    And it wasnt working. I now realize this was due to the fact that in some parts of the file it wasnt finding ints and was breaking. Now with the try/catch Im up and running. I do however, want to improve on this and mess around with pbrockway's suggestion.

    Once again thank you...

      Trouble parsing int while reading a file

      Hello,

      I am having trouble when I read in a a file and parsing part of it as an int using substring.

      Here is the code I have:

      Code:
      String input = "";

while(readFile.hasNextLine()) 
{
     input = readFile.nextLine();
     String sName = input.substring(0, 14);
     String sCap = input.substring(15,29);
     String sAbbr = input.substring(30,32);
      ...

        Think I figured out how to parse it

        Code:
        int sRegNum = Integer.parseInt(input.substring(56));
        Thanks for the help!

          Thanks for the quick reply.

          Will I be able to use the parse int method in the same while statement using substring, or will I have to read it seperate?

            substring

            Hello,

            I am reading in a file and breaking it up using substring. This is working well except for the last part I need to read in needs to be an integer, not a string. I was curious if it is possible to use substring to break up both strings and ints.

            Here is the code I have:

            Code:
            String input = "";

while(readFile.hasNextLine())
            {
            ...
