How I built this so far was I started, before I added gui elements, I had it at a simple console input is then sent to server, and then the server responds. I know the problem is in the code I linked. The "component.text()" is a reference to a JTextField. The class that holds the code I showed you, has two inner classes. Everything works except what I've mentioned about the input is stuck in an infinite loop. The code I linked is working code for A SINGLE interation. If I surround
while(connected)
{
System.out.println("Type in a word to send to the server.");
// Sends the word to the server from the TextField
System.out.print("Sending: " + component.text() + "\n");
out.println(component.text());
out.flush();
// gets the Response from the server
response = in.nextLine();
if(!response.equals("Word does not exist"))
{
wordList.add(response);
System.out.println("Receiving: " + response + "\n");
}
for(String str: wordList)
{
System.out.println(wordCount);
wordCount++;
}
}
the stuff I WANT to do with a while statement, it keeps adding the last input to the ArrayList and keeps increasing wordCount endlessly. Basically.
For pseudo code.
I want to continue to listen for input from the user
Check it against the dictionary
if it's a real word, send it back from the server to the client
add that word to an ArrayList
increase the wordCount (really just there to determine if I've finally got it working so it will only add one word to the ArrayList for that input)
Repeat this process for the duration the game is running.
In the event that I am wrong about everything else working in my code, I will supply the entire 3 classes I am working with.
