if statement not triggering when the thing its evaluating is true [duplicate]

So i have this if statement that checks if a message received from irc, split at the first " " equals "add". The whole message is ";quote add test quote", here is the code.

if(event.getMessage().startsWith(";quote")){
        File quotecheck = new File("quotes.ini");
        if(event.getMessage().contains(" ")){
            event.respond(event.getMessage());
            event.respond("Message Contained Space Key");
            if(event.getMessage().split(" ").length > 0) {
                event.respond("Split longer than 0");
                if(quotecheck.exists()){
                    event.respond("Quotecheck Existed");
                    Wini quotes = new Wini(new File("quotes.ini"));
                    String totalQuotes = quotes.get("Quotes", "totalQuotes");
                    int totalQuotesInt = Integer.parseInt(totalQuotes);
                    event.respond(event.getMessage().split(" ")[1]);
                    if(event.getMessage().split(" ")[1] == "add "){
                        event.respond("Split One Equalled add");
                        int nextQuoteInt = totalQuotesInt+1;
                        String nextQuote = Integer.toString(nextQuoteInt);
                        quotes.add("Quotes", nextQuote, event.getMessage().split(" ")[2]);
                    }
                }
            }
        }

Also, the if that's failing is at line 14

EDIT: This question is different from this question because its im asking why it ISNT working, not how to compare strings
