Question

I’ve been getting this error while trying to load certain data from a txt file.

public static boolean initalize(String FileName) {
    String line = "";

    String token = "";

    String token2 = "";

    String token2_2 = "";

    String[] token3 = new String[10];

    boolean EndOfFile = false;

    BufferedReader characterfile = null;

    try {

            characterfile = new BufferedReader(new FileReader("./Data/data/"

                            + FileName));

    } catch (FileNotFoundException fileex) {
        Misc.println("File not loaded");

            return false;

    }

    try {

            line = characterfile.readLine();

    } catch (IOException ioexception) {


            return false;

    }

    while ((EndOfFile == false) && (line != null)) {

            **line = line.trim();
            int spot = line.indexOf("=");
            if (spot > -1) {
                    token = line.substring(0, spot);
                    token = token.trim();
                    token2 = line.substring(spot + 1);
                    token2 = token2.trim();
                    token2_2 = token2.replaceAll("\t\t", "\t");
                    token2_2 = token2_2.replaceAll("\t\t", "\t");
                    token2_2 = token2_2.replaceAll("\t\t", "\t");
                    token2_2 = token2_2.replaceAll("\t\t", "\t");
                    token2_2 = token2_2.replaceAll("\t\t", "\t");
                    token3 = token2_2.split("\t");**

                    if (token.equals("drop")) {

                            int id = Integer.parseInt(token3[0]);

                            int x = Integer.parseInt(token3[1]);

                            int y = Integer.parseInt(token3[2]);

                            int amount = Integer.parseInt(token3[3]);

                            int height = Integer.parseInt(token3[4]);
                            globalDrops.add(new GlobalDrop(id,amount,x,y,height));  

                    }

            } else {

                    if (line.equals("[ENDOFDROPLIST]")) {

                            try {

                                    characterfile.close();

                            } catch (IOException ioexception) {

                            }

                            return true;

                    }

            }

            try {

                    line = characterfile.readLine();

            } catch (IOException ioexception1) {

                    EndOfFile = true;

            }

    }

    try {

            characterfile.close();

    } catch (IOException ioexception) {

    }

    return false;

}

However, its been giving me this error:

[8/3/12 5:24 PM]: Exception in thread "main" [8/3/12 5:24 PM]: java.lang.NumberFormatException: For input string: "1923     3208    3214    1       0       2       "

This is how the text file is formated:

sque = 1923     3208    3214    1       0       2       Square

Why is this giving me the error? Is it something to do with the /t/ splits?

Thanks

This is the working one:

sque = 1923 3208    3214    1   0   2       Square

However, I’m trying to load over 400 of these and it would be painful to change all of them at once

Replace all this

                token = line.substring(0, spot);
                token = token.trim();
                token2 = line.substring(spot + 1);
                token2 = token2.trim();
                token2_2 = token2.replaceAll("\t\t", "\t");
                token2_2 = token2_2.replaceAll("\t\t", "\t");
                token2_2 = token2_2.replaceAll("\t\t", "\t");
                token2_2 = token2_2.replaceAll("\t\t", "\t");
                token2_2 = token2_2.replaceAll("\t\t", "\t");
                token3 = token2_2.split("\t");**

with

String[] cmd = line.split("=");
token = cmd[0].trim;
String[] numbers = cmd[1].split("\\s+");

The array numbers will contains the numeric string tokens, already trimmed and ready to be interpreted by Integer.parseInt().
