PROGRAM EXPLANATION

Algorithm and explanation

Initialize the deterministic sample values used for choose a value with the ternary operator in java.
Apply Ternary operator and Condition in the order shown by the program.
Print the final result and compare it with the documented sample output.

This Java 17 example demonstrates Ternary operator and Condition 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

Check this

Keep the class name Main and the entry method signature public static void main(String[] args) when using the online compiler.

Check this

Use Ternary operator with compatible Java types; Java checks types and method signatures at compile time.

Check this

Java is case-sensitive, and every statement that requires a semicolon must end with one.

Try it yourself

Practice: Run the program with the sample input, predict its output, and then test one boundary case of your own.
