What are the advantages and disadvantages of using properties files for storing configuration data?

Properties files advantages:

• Simplicity: easy to read and edit manually.
• Lightweight: small size and simple format.
• Well integrated with Java (java.util.Properties class).
• Allows separating configuration from code, simplifying maintenance and changing settings without recompilation.

Disadvantages:

• Lack of support for complex data structures (e.g., nested objects).
• No built-in typing — all values are stored as strings, requiring additional conversion.
• Can be inconvenient for large and complex configurations.
• Limited formatting and comment support within values.

In summary, properties files are suitable for simple configurations, but for more complex cases, formats like YAML or JSON are preferable.
