Question

I am completely stuck on this one. I know my code is correct. It is very simple. I have tried comparing what to null, using .equals, and now .length(), but it keeps catching this exception. Does anyone know what is going on?

public static void findLocations(String what, String near, String near2, String type) {
    StringBuilder responseBuilder = new StringBuilder();
    try {
        URL url;
        String tempURL = "http://.........";

        if (what.length() != 0) { // This line is catching UnsupportedEncodingException
            tempURL += "&category=" + URLEncoder.encode(what, "UTF-8");
        }

        if (near.length() != 0) {

public static String encode(String s,
String enc)
throws UnsupportedEncodingException

The methode “URLENCODER.encode(what, “UTF-8”) is the line, where you get the exception.
