     Or, for even greater clarity:

	private boolean askYesNoquestion(String str) {
	    boolean yes;
	    boolean no;
	    if (str != null && str.equals("yes")) {
	        yes = true;
	        no = false;
	    } else if (str != null && str.equals("no")) {
	        no = true;
	        yes = false;
	    } else {
	        yes = no = false;
	    }
	    return (no != true && yes != false) == true;
	}

(If we put our minds to it, I bet we can turn the one-liner
into an entire class hierarchy with runtime-selected plug-in
provider implementations!)
