Java TwitchBot/PircBot can't read commands in a .txt file like it has to do

Question

I start coding my own TwitchBot in java. The bot is working fine, so my idea was, to replace the hardcoded commands with variables. The commands and messages saved in a text file.

BufferedReader Class:

try {
            reader = new BufferedReader(new FileReader("censored//lucky.txt"));
            String line = reader.readLine();
            while (line != null) {

                String arr[] = line.split(" ", 2);

                command = arr[0];
                message = arr[1];

                line = reader.readLine();
            }
            reader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

Snippet of my bot/command class

if(message.toLowerCase().contains(BufferedReader.command)) {
            sendMessage(channel, BufferedReader.message);
        }

my .txt file:

!test1 Argument1 Argument2
!test2 Argument1 Argument2
!test3 Argument1 Argument2
!test4 Argument1 Argument2

Everything works fine when I have only 1 command+message / line in my text document, but when there are multiple lines, I can't access the commands in the Twitch Chat. I know, that the commands are stacking like !test1 !test2 !test3 !test this.

So my question is, how do I avoid this? And my fear is, that in my actual code !test3 uses the message from my !test1 command.

I'm not quite sure what you are trying to do here, but it seems like you might need to store you commands and messages in a List or Set. Right now you seem to be overwriting them each time around the loop? — Ryan, Aug 05 '19 at 04:25

while (line != null) 
{
   String arr[] = line.split(" ", 2);
   command = arr[0];
   message = arr[1];
   line = reader.readLine();
}

this loop keeps reading each line from the file and overwrites contents of command and message , that means when you have multiple commands in file - only the last line prevails.

If you want to store multiple commands/messages then the command/message variables must be of type java.util.List or HashMap. And then you can match based on contents.

Eg.,

Map<String,String> msgMap = new HashMap<>();
while (line != null) 
    {
       String arr[] = line.split(" ", 2);
       if(arr[0]!=null)
         msgMap.put(arr[0],arr[1]);
       line = reader.readLine();
    }

This is a good method ty <3 but I never worked with HashMap so I dont know, how can I implement it in bot/command class? because msgMap.keySet() dont work. I mean the snippet is searching in the message for a single String not a Map of them. — Hyku, Aug 05 '19 at 16:09
Map is a key value pair store. If you have the key you can get it with msgMap.get(key) — Kris, Aug 06 '19 at 04:46
