PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the deterministic sample values used for call an overridden parent method in java.
- Create the required object and apply super and Method overriding to its state or behavior.
- Print the final result and compare it with the documented sample output.
This Java 17 example demonstrates super and Method overriding 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.

Common mistakes
Keep the class name Main and the entry method signature public static void main(String[] args) when using the online compiler.
Create an object before accessing instance members; static members can be accessed through the class name.
Java is case-sensitive, and every statement that requires a semicolon must end with one.
