In the command line, you write: java ProgramName value1 value2 and then, when the program runs, the main method creates an array of Strings for you to use later iin your program. If you don't pass any parameter, the array will be empty. That's why you write: public static void main( String[] args )... example: if you run the program by typing: java NameList John Robert Donna args[0] = "John" args[1] = "Robert" args[2] = "Donna" keep in mind that you don't pass the parameters when you compile the program with javac command but only when you run it with java command. Hope I helped.

It's funny how the top answer doesn't have anything to do with the question and still it's the top answer...
