    Smile Reading text file

    Hello,

    I have to read a text file, which the first line contains 2 numbers (integers) and then assign these to variables.

    Here's the first few lines of the text file:

    25 100
    SEND 2228161 Hello Pete
    RECEIVE 2228161 Hello Chris, how are you?
    SEND 2227765 I hate text speak
    RECEIVE 2228876 wot u on bout
    SEND 2227975 The quick brown fox jumped over the lazy dog

    Would I use the String.parseInt(value1) like this

    sizeOfMessage = value1;

    and String.parseInt(value2)

    sizeOfBox

    I then have to go on and read different String lines like SEND and RECEIVE
    where I have used the if (line.startsWith("SEND")

    Thanks for your help

    Default

    You could try something like this (in pseudo code):
    Java Code:
    Scanner scanner = new Scanner(yourFile);
    String line = scanner.nextLine();
    String[] data = line.split("\\s");
    // Check what we have here:
    System.out.println(Arrays.toString(data));
    int sizeOfMessage = Integer.parseInt(data[0]);
    int sizeOfBox = Integer.parseInt(data[1]);
    // carry on reading...
