Which statement best describes String[] args?

• A. A string array containing all class names.
• B. The return type of the main method.
• C. The program's source file name.
• D. Command-line arguments passed to the program.

Answer: (D)

The statement is about how command-line inputs are given to a Java program when it starts. In Java, the main method typically looks like public static void main(String[] args). The args parameter is a String array that holds any tokens you supply after the class name when you run the program from the command line. If you don’t pass anything, this array is empty (length zero). For example, running java MyProgram hello world would place "hello" in args[0] and "world" in args[1]. This is why the correct description is that String[] args are the command-line arguments passed to the program. It’s not a list of class names, nor the program’s source file name, and it’s not the return type of main (which is void in Java).
