In other words, the Java environment or Java application is not in an appropriate state for the requested operation. After evaluating the approaches for asserting exceptions described above, I would avoid both @Test with expected and @Rule with ExpectedException approaches, as they may lead to false positive results.. For Java 7, simply stick to the try-catch with fail() approach, even if the test look a bit clumsy.. An IllegalStateExceptionis an uncheckedexceptionin Java. IllegalArgumentException Whenever you pass inappropriate arguments to a method or constructor, an IllegalArgumentException is thrown. Generally, this method is used to indicate a method is called at an illegal or inappropriate time. The first example we'll go over uses our own Book class and explicitly throwing an IllegalStateException: The first critical method for this code example is the Book(String title, String author, Integer pageCount, Date publishedAt) constructor, which allows calling code to pass in a publication date: The other important method is publish(), which checks if a publication date already exists, in which case it throws a new IllegalStateException indicating that the book cannot be published a second time: This is simple logic, but it illustrates how you might go about using the IllegalStateException in your own code. So instead of creating a new try and catch block to handle this exception, we can just use the throws keyword to throw the possible exception that might occur. There are many collections like List, Queue, Tree,Mapout of which Listand Queues(Queue and Deque) to throw this IllegalStateExceptionat particular conditions. * * @throws IOException * @throws URISyntaxException */ private static void processResponse(final HttpURLConnection connection) throws IOException, URISyntaxException { try { logConnection(connection); } catch (ConnectException exception) { // Output expected ConnectException. agreement.
