ClassNotFoundException: class not found by name

A ClassNotFoundException in Java occurs when the system cannot locate a specific class that was previously referenced.

The error message might look like this:

  1. Exception in thread "main" java.lang.ClassNotFoundException: com.example.MyClass

Here, com.example.MyClass is the class name that couldn’t be found.

To fix this issue, you should:

  1. Check if the class file exists in the correct package directory.
  2. Make sure the class has been compiled properly (either using javac or through an IDE).
  3. Verify that the class name and package are spelled correctly.

If all of these steps are taken care of and the error persists, it could be a problem with the runtime environment or with the build process.
