Question

I am reading in a file that is being sent though a socket and then trying to split it via newlines (\n), when I read in the file I am using a byte[] and I convert the byte array to a string so that I can split it.

public String getUserFileData()
{
    try
    {
        byte[] mybytearray = new byte[1024];
        InputStream is = clientSocket.getInputStream();
        int bytesRead = is.read(mybytearray, 0, mybytearray.length);

        is.close();

        return new String(mybytearray);
    }
    catch(IOException e)
    {

    }

    return "";
}

Here is the code used to attempting to split the String

public void readUserFile(String userData, Log logger)
{
    String[] data;
    String companyName;

    data = userData.split("\n");

    username = data[0];
    password = data[1].toCharArray();
    companyName = data[2];
    quota = Float.parseFloat(data[3]);

    company = new Company();            
    company.readCompanyFile("C:\\Users\\Chris\\Documents\\NetBeansProjects\\ArFile\\ArFile Clients\\" + companyName + "\\"
            + companyName + ".cmp");

    cloudFiles = new CloudFiles();
    cloudFiles.readCloudFiles(this, logger);
}

It causes this error

Exception in thread "AWT-EventQueue-1" java.lang.ArrayIndexOutOfBoundsException

You can use the readLine method in BufferedReader class.

Wrap the InputStream under InputStreamReader, and wrap it under BufferedReader:

InputStream is = clientSocket.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));

Please also check the encoding of the stream – you might need to specify the encoding in the constructor of InputStreamReader.
