Check if account gets banned

[flickyUh]

How can I check if an account gets banned? So i can mark it as such in my database and create a new one to replace it.

Thanks

public void onResponseCode(int code) throws InterruptedException {
		log("Code: " + code);
		switch(code){
		case 4: 
			log("BANNED");
			sleep(3000);
			System.exit(0);
			
		}
	}
