Solution
Command-line arguments in a Java program are passed to the main() method as arguments in the main(String[] args) method signature. Here's how it works:
-
When you launch a Java application from the command line, you actually use the Java interpreter, which is part of the Java Runtime Environment (JRE).
-
You type 'java' followed by the name of the class that contains the main() method. Any arguments that follow the class name are passed as command-line arguments.
-
These command-line arguments are received in the main() method as an array of String objects, through its argument - String[] args.
-
Inside the main() method, you can access these arguments by referring to the elements of this String array.
So, the correct answer to your question is D: "As arguments in the main(String[] args) method signature".
