import net.sourceforge.msscodefactory.cfsecurity.v2_6.cfsecurity.CFLib; import net.sourceforge.msscodefactory.cfsecurity.v2_6.cfsecurity.CFLibExceptionFactory; public class MyExceptionFactory { public static void main(String[] args) { // Get default exception factory CFLibExceptionFactory factory = CFLib.getDefaultExceptionFactory(); // Create custom exception message with error code Exception e = factory.getException("500", "Internal Server Error"); // Print exception message System.out.println(e.getMessage()); } }In this example, we import the necessary packages and use the getDefaultExceptionFactory method to get an instance of the CFLibExceptionFactory class. We then create a custom exception message with the error code "500" and message "Internal Server Error". Finally, we print the exception message. Based on the package name, this library appears to be related to security and provides tools for secure coding.
