An exception is an unwanted and unexpected error thrown in the program. Most of the time, an exception occurs when there is an error in our code but it can be handled. It disrupts the normal flow of the code. For example, the code throws an exception if the user has entered invalid information, if the code is unable to read the file located at the remote place, or if the network connection is lost in the middle of the communication. IllegalStateException is the sub-class of RuntimeException class, and therefore it is an unchecked exception. It is raised by the programmer or by the API developer explicitly. It is thrown when a method call illegal or a method is called at incorrect time. For example, once we start a thread, we cannot restart the same thread again; if we try to do that, it throws a runtime exception i. The exception may arise in the code usually when we are working with the Collections framework. The List, Queue, Maps, Tree are some of the collections. Out of these, List and Queues tend to throw the illegal state exception at the specific conditions. The following Java program depicts the situation where we try to call the start method when the run method is already executing. The following code depicts the situation where we call the start method on a thread when the execution of run method is over.

The "proper" use of the IllegalStateException class is somewhat subjective, since the official documentation simply states that such an exception "signals that a method has been invoked at an illegal or inappropriate time. In other words, the Java environment or Java application is not in an appropriate state for the requested operation. Throughout the rest of this article we'll explore the IllegalStateException in greater detail, starting with where it resides in the overall Java Exception Hierarchy. We'll also look at a couple functional code samples that illustrate how IllegalStateExceptions are used in built-in Java APIs, as well as how you might throw IllegalStateExceptions in your own code, so let's get started! All Java errors implement the java. Throwable interface, or are extended from another inherited class therein. The full exception hierarchy of this error is:. Below is the full code sample we'll be using in this article. It can be copied and pasted if you'd like to play with the code yourself and see how everything works.
