Question

What’s a simple method of checking if a string contain error 404?
The string was built from HttpGet.

Any help is appreciated.

Answer 1

You should better check the status code, the result string of a HTTP request is not guaranteed to contain the error code, if the status is 404.

If it’s Apache HTTP client (which it looks like, because you mentioned HttpGet):

get = new HttpGet("http://www.google.com");
response = client.execute(get);
if (response.getStatusLine().getStatusCode() == 404) {
    System.out.println("404 - Not found!");
}
