what does "io unsupportedoperationexception not readable" mean?

When dealing with computer programming and software engineering, one might come across the term "IO (Input/Output) UnsupportedOperationException Not Readable". In this article, we'll discuss what this message means and why it may be encountered.

At its simplest definition, IO UnsupportedOperationException is a Java Exception that basically means that an operation was attempted which cannot be completed by the current platform or environment. This exception occurs when trying to access something that is not supported or not readable. It is thrown when a read-only resource or object does not allow for an operation or function to take place.

A few examples of when the exception could be thrown include attempting to modify the content of an unmodifiable file, an attempt to write to a resource without permission, and attempts to modify an input stream from a file that cannot be modified. This exception can occur in any of these scenarios, as these cases simply indicate that there is an attempt being made on an object which can't be done as it does not support the functionality being attempted.

The way you respond to this exception depends on what caused it in the first place and why this function is required in your program code. In most cases, reading up on ways to work around privacy issues and unmodifiable files should do the trick and you can learn how to bypass those restrictions in order to complete your tasks. Sometimes it's also possible to just ignore certain operations if they're deemed unnecessary for your program's function by discarding them as "unnecessary complexity".
