It seems that there is an issue with running the Java application "jp.mynavi.api.DemoApplication". The error message "java.lang.ClassNotFoundException: jp.mynavi.api.DemoApplication" suggests that the class cannot be found.

There are a few possible reasons for this error:

1. The class "jp.mynavi.api.DemoApplication" does not exist or is not in the correct package. Double-check the package and class name to ensure they are correct.

2. The class file is not in the classpath. Make sure that the class file is compiled and located in the correct directory. You may need to specify the classpath explicitly when running the Java command.

3. There may be an issue with the Java installation or environment variables. Make sure that Java is properly installed and the JAVA_HOME environment variable is set correctly.

Try resolving these issues and running the application again. If the problem persists, provide more information about your project structure and how you are running the application for further assistance
