Question

This is my code to download and read the text in my file in Dropbox. Version is a URL.

BufferedReader in = new BufferedReader(new InputStreamReader(version.openStream()));
String inputLine;
int line = 0;
try{
    while ((inputLine = in.readLine()) != null){
        strings[line] = new String(inputLine);
        line++;
    }
} catch (Exception e){
    e.printStackTrace();
}

Although, I get this really annoying error.

java.lang.ArrayIndexOutOfBoundsException: 1
at sky.the.venture.client.Download.getCredits(Download.java:38)
at sky.the.venture.client.LauncherFrame.credits(LauncherFrame.java:315)
at sky.the.venture.client.LauncherFrame.(LauncherFrame.java:49)
at sky.the.venture.Destiny.(Destiny.java:13)
at Start.main(Start.java:11)

So, the part which is an error is Download.java:38. Which is

strings[line] = new String(inputLine);

So if anyone can help, I will be really happy =D

Well presumably you only created an array like this:

String[] strings = new String[1];

Arrays don’t resize themselves in Java – indeed, they can’t be resized. If you want a dynamically sized collection, use a List<E> implementation e.g. ArrayList<E>:

List<String> lines = new ArrayList<String>();
while ((inputLine = in.readLine()) != null) {
    lines.add(inputLine);
}
