English parsing crap

yugiooooooooooh.java

String text = "attack 500." //description of card
String[] sentences = text.split("."); //each sentence will be parsed as a command

ArrayList<Token> tokens = new ArrayList<Token>(); //each sentence translates to a set of tokens


for(String s : sentences)
    for(String word : s.split(" "))
        if(word.equalsIgnoreCase("attack"))
            tokens.add(new AttackToken()); //add attack token if the word is Attack
        else if(word.matches("[0-9]+"))
            tokens.add(new NumberToken(Interger.parseInt(word)));

    if(tokens.get(0) instanceof AttackToken && tokens.get(1) instanceof NumberToken)
        generateCode("attack " + tokens.get(1).getNumber())
