IOException cannot be resolved to a type

The "IOException cannot be resolved to a type" error is a common error in Java that occurs when the compiler is unable to recognize the IOException class.

Here are a few reasons why this error might occur:

1. The IOException class has not been imported: To use the IOException class in your code, you need to import it using the following line at the top of your file:

import java.io.IOException;

2. The Java I/O library is not included: The IOException class is part of the Java I/O library, so if you are using an IDE such as Eclipse or IntelliJ, make sure that the Java I/O library is included in the project build path.

3. The classpath is not set up correctly: If you are compiling your code from the command line, make sure that the classpath is set up correctly to include the Java I/O library.

By addressing these issues, you should be able to resolve the "IOException cannot be resolved to a type" error.
