Loading Runtime Configurations:

You usually don't need to recompile if your program is configured to read the property file dynamically at runtime. As long as the program can detect or reload changes, many frameworks, including Java's Spring Boot, let modifications to property files without recompilation. Compilation-Time Property Embedding: You must recompile your project in order for changes to take effect if property file values are embedded within the compiled code (for example, by being turned into constants or included in the build artifacts). Frameworks for Development Tools: Changes may take effect automatically without the need for manual recompilation or restarting if you're using a framework or tool with hot-reloading capabilities, like webpack in a JavaScript project or devtools in a Spring Boot application.
