majformedURLException

MalformedURLException is a Java exception that indicates a problem with a URL string. It is part of the java.net package. This exception is thrown when a URL string is not syntactically correct. This can happen for several reasons, such as invalid characters, incorrect protocol format, or missing components. For example, a URL like "http:/example.com" would be considered malformed because it is missing a slash after the protocol. Similarly, a URL containing spaces or other characters not permitted in a URL can also cause this exception.

When a MalformedURLException occurs, it typically means that the Java runtime could not interpret the provided string as a valid URL. This prevents operations that rely on the URL, such as attempting to connect to a web server or access a resource. Developers often encounter this exception when parsing user input or configuration files that contain URLs. It is important to validate URL strings before attempting to use them to avoid unexpected program termination.

To handle MalformedURLException, programmers typically use a try-catch block. Inside the try block, the code that creates or uses the URL is placed. If a MalformedURLException is thrown, the catch block can handle the error gracefully, perhaps by logging the invalid URL, displaying an error message to the user, or providing a default value. Proper error handling ensures that applications remain stable even when encountering malformed URL data.
