Java provides a mechanism for handling errors and exceptional situations called exceptions. An exception is an object that describes an error or an abnormal condition that has occurred during program execution. Exceptions can occur for various reasons, such as incorrect input, network problems, or system errors. Java also provides a way to handle these exceptions … Read More “Java | Throwing and propagating exceptions” »
