No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

This error message means that the Java compiler (javac) is not available in the current environment. This can happen if you are running a Java program from a Java Runtime Environment (JRE) rather than a Java Development Kit (JDK).

The JRE is a package that contains the necessary runtime libraries and files to run Java programs, but it does not include the development tools (such as the compiler) that are necessary to create Java programs. The JDK, on the other hand, includes both the runtime environment and the development tools.

To fix this error, you will need to install the JDK and ensure that it is correctly configured on your system. Once the JDK is installed, you should be able to compile and run Java programs.

I hope this helps! Let me know if you have any other questions.
