PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the deterministic sample values used for pass method parameters in java.
- Apply Parameters and Arguments in the order shown by the program.
- Print the final result and compare it with the documented sample output.
This Java 17 example demonstrates Parameters and Arguments through a complete, executable program. The values are intentionally small so students can trace each statement, verify the output, and then modify the example safely in the online compiler.

DEBUGGING CHECKLIST
Common mistakes
Keep the class name Main and the entry method signature public static void main(String[] args) when using the online compiler.
Use Parameters with compatible Java types; Java checks types and method signatures at compile time.
Java is case-sensitive, and every statement that requires a semicolon must end with one.
