This error message usually means that the compiler or interpreter cannot find the JFrame class. This can happen if you are using an older version of Java that does not include the JFrame class, or if you have not imported the javax.swing package, which contains the JFrame class.
To fix this error, make sure that you are using a version of Java that includes the JFrame class (Java 7 or later), and that you have imported the javax.swing package at the top of your Java file:
```
import javax.swing.JFrame;
```
If you are still experiencing this error, try checking your classpath to make sure that the required Java libraries are included.
